We finished this today and I have nothing but good things to say about it. I'm so thankful this resource is out, and that I can enjoy math again.

Since starting this book, I have seen my 7 yr old and 9 yr old gain confidence in their math skills. It has also helped me teach math consistently- I know what to say during the lesson and the lessons are short and engaging. It provides ample practice without being too repetitive and progresses nicely. It has instructions for the teacher on how to teach the material, a schedule in the front as well as a few short exams. The arithmetic concepts covered in this book are: Counting 1 through 100, Investigation and analysis of 1 through 100, Numerals 0 through 9, Symbols +, –, and =,
Place value through 100, Numeration and notation through 100, Money through $1 (penny, nickel, dime, quarter, dollar), Addition through double digits, Subtraction through double digits, Skip counting, Review and oral work, Mental math. It has been a blessing to use! Baburina's other book "Mathematics: An Instrument for Living Teaching" is also a wonderful resource which I read alongside teaching Arithmetic #1.

I really enjoyed this approach to math, which makes it a cozy conversation between parent and child. We spent so many hours delving into numbers and their behavior, grouping manipulatives or sliding beads across the abacus, wrestling with coinage, and trying to strategize the best approach to take in a word problem.

My pupil is not, I think, mathematically minded by nature. Much of this was a struggle for him. But that's precisely why I was so glad we could take the journey together: companionship takes the edge off difficulty. And it was a joy to see him learn to apply himself and master concepts that he found challenging. It took us a long time to work through especially the early part of this book—partly due to my own inconsistency—but I think we succeeded in building a solid foundation that will serve instead of aptitude as we progress in this discipline.

I can't wait to start Book 2!

I’ve worked through this book with two children (5-6yo and 7-8yo). They both really liked it and rarely complained when it was time to do math. The older child got through much more quickly. I was really impressed at their ability to do so much in their minds, and it improved my mental math as well.

Since there is no entry for Book 2, I’ll say here that I’m a little confused at how elementary it is. The kids end Book 1 doing calculations using high 2-digit numbers and then Book 2 seems to regress. The first third is very simple review (as in single-digits). They have gotten bored.

My goodness this math book was excellent. A bit of a learning experience at first since it’s so different than I was used to. I grew up on only worksheets and occasionally sprinkled in a word problem. This starts out doing word problems only. Full focus on the habit of attention. Parent-Teacher dictates the question, child remembers the numbers in the question, either uses manipulatives or mental math to solve the problem, then has to answer how she came to each conclusion.

Ex: Miles picked 51 pears. He gave 25 to his neighbors. How many had he left? He has 26 pears because 51-25=26 or however the problem was solved.

This book focuses on numbers 1-100, addition and subtraction. The answers are at the bottom of each section, so don’t hand your child the book for her to work on on her own.

Year one book was able to be completed without writing in it. I can use for multiple kids! Well worth the money.

Can’t wait to jump into year 2!

Lots of mental math which was even a challenge for me as I worked through this with my 1st Grader. I was really pleased with the learning that took place and could definitely see a lot of growth by the end. Excited to work through the next book in this series.
