I love the illustrations and the idea behind the story. It tries to educate kids about a chinese food item called dim sum and incorporate the idea of the Chinese Zodiac as well.

However, I feel it will be a bit much for the kids to actually take in the concept when it's a bit rushed and not explained well through the pictures and their description.

A fun, family read still.

Thank you, author and the publisher, for the copy.

I found this picture book by Natasha Yim to be absolutely delightful. The illustrations by Violet Kim capture the cultural diversity portrayed, plus the dumplings do look good enough to eat--and to fight over how to divide them so that each child gets an equal share.

A family goes out for Dim Sum on Luna's birthday. She has an older brother and a younger brother. Six dumplings are brought so that each child may have two. Luna is so excited, she accidently drops one of her dumplings; thus causing much discussion on who should get the remaining five dumplings. Three children and five dumplings.

The book teaches children the concepts of division and fractions and sharing. It also introduces the Chinese zodiac and dim sum. There are even suggestions for parents to help their children explore math concepts.

Luna’s Yum Yum Dim Sum is a clever picture book about food, culture, sibling dynamics, and of course, math! When a dinner outing takes a sad turn, Luna and her brothers have to engage their math and negotiation skills so that they can all get two pork buns each. If you enjoy funny picture books that provide ample opportunity to learn about culture, do some counting, simple addition, subtraction and division, this is an excellent choice!

I received this book from the publisher/Netgalley in exchange of an honest review.


When I saw this book I was at first a bit hesitant. I am not a fan of maths. Not ever. I hated it. And I also honestly forgot most of my high school (we don’t have middle school here) maths and such. Basic stuff is still in my head easily, but don’t ask me anything like Pythagoras or how those things with x and ys work. 😛 But the rest sounded very cute and I loved the cover. Plus, hello, food? Sign me up!

Happy birthday to Luna, it is her big day and she is going to a dim sum restaurant with her family. Food, more food, and family, what more could one wish on a birthday (presents… all the presents).

The food arrives but an accident happens! One of the 6 buns (which are apparently for the kids why aren’t the parents getting anything) one falls! Oh no! Now there are two buns left! I did find it weird that they just went in a discussion on who gets what and why, when here in my country it is just OK to ask the waitress/waiter/someone else in charge, to ask for a new item if you drop it. No problem. You just get a new one. But I guess that is either different where Luna lives or they just needed to have a set-up for the fractions/maths part. I also found it weird that neither dad nor mom came between. Plus again, they didn’t seem to eat anything??? What is this?
But I did like the arguments each kid has and that they were working out on how to share evenly.

Though then there is the ending and whut? I guess it is cute, but did they forget the parents? Also, Luna is the birthday girl, why aren’t her brothers a bit more kinder and just giving it to her? Also why are the parents not eating? All in all, a book that could have been better. The set-up could have been worked out better. Now it just felt silly because as I said, it is Luna’s birthday and also why is no one asking the waiter/waitress for help on getting a new bun?
Cute idea, fun art, but yeah.. I am sadly not rating this one very highly because of everything.

There is so much to love about this book! I love that Luna’s family Is biracial. I love that there is diversity in the Dim Sum restaurant they go to. I absolutely love that the children use math to share their food equally, and that they share with another child as well. The illustrations are so fun, colorful, and detailed. The author included some Chinese zodiac signs which made this even more fun. All around a wonderful book that I would purchase for sure. So cute!!!!
Thank you NetGalley for allowing me to read this book in exchange for my honest opinion

My favorite yet in the Storytelling Math series. That could just be because I love dim sum, and it made me hungry. :) But I like these sibling sharing stories that highlight various global cultures.

This book is about a young girl named Luna and how she shares her Dim Sum with her family. She learns about being fair when dividing their food. This story highlights Chinese cuisine and their close knit family culture. This book would be great in my classroom because it opens up a wide variety of discussions such as math when speaking about sharing, family culture, and traditions as well. The extended audience for this story would be PreK-2nd Grade.

I was really curious about this new series Storytelling Math because it sounded promising, but sometimes these types of books can be heavy-handed with the lesson and not tell an enjoyable story. Instead, we had a lovely story about Luna and her family going out for dim sum on her birthday and figuring out how to split up pork buns among themselves. They discuss different ways to decide (some sillier than others) and model how to think about the concept underlying fractions/division without explicitly talking about "math".

Luna's Yum Yum Dim Sum is so cute and fun! I absolutely adore the illustrations, and it made me hungry for some pork buns! Yim finds a way to get ids involved in the math that is involved in sharing food, and I loved the probing questions around who should get more (and why) that are at the heart of distinguishing between equity and equality. There's an excellent short discussion guide at the end, and I know that my niece (age 5) would love to read this with me and talk about it!

This Book is about a little girl named Luna who is going out to lunch for her birthday with her parents and two brothers. At the restaurant they order two baskets of dim sum buns and each basket has three buns. This briefly shows a multiplication problem. While grabbing a bun Luna accidentally drops hers and it splats on the floor. Luna and her brothers then have to find out how to evenly divide the buns among themselves.
This book addresses the equal groups with group size unknown division because they know that there are 5 buns and they know that they have 3 people but they don’t know how many buns each person gets. Throughout the story, you see the numbers represented visually in picture form and written out. An example of this is when the dad holds up two fingers while ordering two baskets of dim sum. Another example would be when they say they can split both of the dumplings in half and it shows the four halves of dim sum on the page. This scaffolding supports students' learning because they are able to visualize what the words of the fractions represent. This book as a whole acts as scaffolding for division because it gives students a real-world example and visual to tie the ideas to to build understanding.
This book is also a good representation of problem-solving for students because in the story Luna and her brothers have to come up with several different ideas of how to divide up the food and they don’t give up after their first attempt.
Chapter 8 also introduces the topic of partitioning and this book is a great resource for introducing students to the concept of partitioning. They don’t waste the other two buns and label them as remainders and with Luna being insistent that she gets more than one bun since it's her birthday they also don't leave Luna's portion as an incomplete set.
In a classroom, I would use this book to introduce students to division that doesn’t work out evenly. I think that this is a great way to teach students about partitioning because it makes sense that they would partition the dim sum buns in this book. I would use this book with an activity where students could pick their favorite food and have them figure out how to divide one less than double the amount of that food item among all of the people in their immediate family. I think that this would be a rich learning activity because it would be a multistep equation and it would stretch them as learners. If some students need an easier problem you could do the first two steps for them and just have them do the last division problem rather than the multiplication, subtraction, and then division.
This would be a good activity because it would tie in the concept of “Number Sense in Their World” from Chapter 7 in our textbooks because they can then relate division to a possible dinner table situation and they can begin to see division as an everyday occurrence (Van D Walle).

Luna and her two brothers order two baskets of char siu bao, each of which has three buns, so they know they'll each get two (small bit of multiplication/division, or at least commuting multiplication). But Luna drops one, so now there are five! They can each have one, but what to do with the two leftover? Each sibling makes arguments for why they should get one before they decide to split them, cutting each in half. They each get a half, and then there's one more half left over. After more discussion, they realize splitting in half again will get them back to the original problem. And they could split in three, but those would be very small pieces. So they give the extra half to a friend.

While they settle for fair division, the discussions could bring up questions of "unfair" division sometimes being fair, and the questions in the backmatter reinforce this.

Of the picture books in this series so far, this feels like the most typical math picture book story. Division of things fairly is a relatively common story. This also builds the most directly in mathematical ideas on the board book in this series, The Last Marshmallow.

I like the kids figuring out how to split things, but where are the adults? Do they not want char siu bao?

Reviewed from a PDF copy.

A fine addition to a new series of picture books that weaves math into a fictional story, similar to Stuart Murphy's MathStart series. There are three others in this series.

Luna's family are going out to eat dinner at their favorite dim sum restaurant in order to celebrate her birthday. When their dim sum arrives, they do the math (2 buns for each child), until she drops one of hers. This sets up the dilemma: who will be short a bun? Luna comes up with the perfect answer that is full of kindness.

Simple, yet predictable, this story sets up a perfect application of division in action. The pacing is good for beginning readers and younger listeners. Also, Yim weaves in a mention of the Chinese Zodiac (shengxiao) in the text to add another detail of culture to the story. Violet Kim's colorful digital (?) images are full of fun detail and family. Unfortunately all characters have dots for eyes, so it is difficult to differentiate Europeans from Asians in the restaurant or to know if this is a biracial family. (There is a difference of shades for skin to separate Black families.)

Pair this with Pat Hutchins' The Doorbell Rang (Greenwillow Books, 1989) for a yummy storytime fit to eat!

Recommended for PreSchool-grade 3.

First sentence: It's Luna's birthday! Ma Ma and Ba Ba are taking Luna and her brothers to a dim sum restaurant for a special birthday lunch.

Premise/plot: Luna's Yum Yum Dim Sum is a math problem in disguise--not really, it says right on the cover. Luna, the birthday girl, gets into a dilemma with her two brothers Kai and Benji. There are six pork buns (char siu bao) to divide between the three of them. (I'm guessing the parents ordered something different. Honestly the parents might as well not be in this one). So what will happen when ONE of the six falls on the floor? How will the three kids divide five between the three of them? Can they agree on what's fair?

My thoughts: I may not love, love, love math, but I do love to eat! I enjoyed this one. The children solve how to share/divide the food between themselves without any interference or input from the parents. (We never do learn what the parents ordered. I was curious.) Is that wishful thinking? Maybe. Maybe not depending not only on the kids' ages but on the kids' personalities as well!

Luna's Yum Yum Dim Sum by Natasha Yim is a fantastic book. Luna celebrates her birthday at a special restaurant to eat dim sum.

The illustrations bring to life unfamiliar foods and the vibrant characters at the restaurant leap off the page. Luna and her brothers are trying to find a way to share pork buns, so math is introduced in a relatable way for young children.

The themes of fairness, creativity, collaboration, and cooperation are introduced. Luna and her brothers find an out-of-the-box solution to resolve their conflict. An excellent Introduction to other cultures and traditions was also provided.

The book will keep little ones engaged with the colorful illustrations and short text on each page. My almost four year old was a big fan! He was interested in trying some new foods also thanks to this book!

I was provided a free advance reader copy from Charlesbridge n exchange for my honest review on Net Galley. The opinions shared in this review are my own.

This was a lovely illustrated book and I love that the book focuses on Chinese culture in a way that can allow children to learn more about it. I could see it being great for Chinese New Year in schools to prompt discussion and learning. The book also has scope for a lot of discussion and maths related discussion on sharing, fractions, counting, times tables and arrays. I think if used in conjunction with discussion in class it could be a great topic book for the week. I think if you are reading the story for itself rather than as a talking point then you won’t get as much from the book. Clever idea, my only thing is I felt like some areas needed to be more developed for the maths, but if only using as a starting point it offers a lot of scope for engagement and learning.

They order 2 baskets of 3 buns, so they know that's 2 buns for each of the 3 of them. Love the way they know that 2x3 = 3x2.

When one bun is dropped, they think of several ways to split 5 buns among 3 children. They end up with one each and then cutting the last 2 in half and they each take 1 half. There's a half left and the arguments start again on who should get the last half. They DO mention they could cut it in 3 pieces, but they end up giving it away.

Read with One, Two, Three Dim Sum: A Mandarin-English Counting Book for a bilingual (Mandarin-English) counting book that features dim sum foods.

Luna's family is going out to celebrate her birthday at a delicious dim sum restaurant. The three siblings are meant to share six pork buns, but when Luna accidentally drops one, suddenly there are only five left. Obviously the older brother deserves more--because he is the oldest! Though maybe the younger brother deserves more--because he is the smallest. But it IS Luna's birthday, so surely she deserves more? Discover how the siblings figure out how to divide the remaining buns equally among themselves.

This was so cute! I like that Luna's family is biracial, and, of course, pork buns = yum! The simple math and diversity of this new book series (story telling math) is much appreciated too.

It's Luna's birthday. She and her family go to the dim sum restaurant to celebrate. The three siblings are very excited to eat pork buns, but when 1 bun falls on the floor and they are left with 5 buns to divide amongst 3 siblings, they have to brainstorm how to make it fair. Should the eldest get more or the birthday girl, or should they go by their Chinese zodiac animals, or maybe could they figure out how to divide them evenly?

Problem solving with your siblings about how to make things fair can be a huge challenge. I like the unique things that this biracial Chinese American family pull into the mix. There's a nice element of kindness that helps resolve the story, but there's also some fraction math involved too.

I really like this book as an adult – and the illustrations were lovely!

The book uses food to work out some maths problems and that is something that will really help kids – maths is not the greatest for a lot of children – it certainly wasn’t my strongest area, so any book that uses a different way or a fun story to try and help is good with me.

The story is easy to follow and understand and it is probably one for slightly older children that have already been at school for a couple of years as opposed to a book for younger kids.

It is 4 stars from me for this one – a great idea that was well developed – highly recommended!

I received an electronic ARC from Charlesbridge through SLJ Day of Dialogue.
Part of the Storytime Math series.
To celebrate Luna's birthday, her family goes to a Dim Sum restaurant. When Luna drops her pork roll, the three kids have to work through fractions to make sure everyone gets a fair amount. Charming ending when Luna shares the leftover half with the little boy at the table behind them.
The realistic drawings bring the culture and the needed math to life.
Informative text at the end of the book.

I voluntarily read and reviewed a advanced copy of this book. This book is well written and the character's are described well. This is such a cute little book. I would definitely read this to my niece when she gets older. The writing style is good for little kids to enjoy this story about family and dim sum pork buns. The illustrations are gorgeous. This book is in stores now for $14.99 (USD). I can not wait to read more books by this author in the near future. I highly recommend it to anyone and everyone.

When Luna's family goes out to eat for her birthday celebration, the three siblings are faced with having to equitably split five dim sum. Each sibling offers reasons why they should receive two (including priority based on the Chinese lunar calendar), but they start dividing based on mathematical principles and, in the end, they are saved from dealing with a small 1/6th size piece when a young boy at the adjoining table shares one dim sum with Luna. Back matter includes information about dim sum, the Chinese zodiac, and other ideas for dividing food.

This was a fun story about a little girl celebrating her birthday and eating dim sum with her family. What happens when she drops one and now they have to decide how to divide five buns up between three people. A fun story with a little touch of math! The artwork is really cute and I definitely think this will make a great read for kids!

Reading this in a CV-19 time makes me realize the way of dim sum houses may well be extinct in my local Chinatown. Therefore, I see great cultural value in the end pages where the creators help explain dim sum/yum cha.

While I definitely enjoyed every page where Luna breaks into a Birthday Crown fantasy, I was disappointed the siblings never thought to share with their parents. I felt that would be more "true" to the story than passing a small piece to a stranger.

I appreciate the lessons in math and kindness, but how often do we tell kids to not accept food from strangers?

This book had plain yet clear and very good illustrations. I really appreciated the character diversity and the book had multiple pages that younger students would be able to use for math problems. A strategy for this book would be asking the students about these problems while they are listening. Alongside the math problems, the book also had parts where students could make decisions and potentially relate to sharing food with their siblings.

Luna and her family go out to celebrate her birthday at a dim sum restaurant. Her and her siblings have to problem solve on how to equally share the food. I really enjoyed the elements of Chinese culture that were portrayed: food, vocabulary, respect for elders, and even reference to the Chinese zodiac! The siblings have to put some math and problem skills to the test to fairly divide up the food. There is a kind hearted twist at the end as they discover a solution. Now I want to eat dim sum.

I like how this book gently introduces the concept of division and fractions for older preschoolers and young elementary students through sharing.
Luna is a cute character, and it's her birthday, so she's hoping for some yummy dim sum. Her older brother and younger brother are also big fans of dim sum. The three kid characters are all familiar with some math concepts and their numbers already...so this book is not for the very young who don't know their numbers yet.

This book will hold great appeal for kids and adults familiar with dim sum or who've experienced the drama of trying to share delicious treats with siblings. During Luna's birthday lunch her and her brothers have to figure out how to share an odd number of steamed buns. They try to do so fairly and also try to justify why each of them should be the one to receive more than the others.
