Digital Arithmetic Flash Cards (Boxed Set: 4 Books in 1): Addition, Subtraction, Multiplication, and Division

by Chris McMullen, Carolyn Kivett

Arithmetic Flash Cards Boxed Set 4 Books in 1 This boxed set includes 4 flash cards Digital Addition Flash Cards in Color (Ordered and Shuffled 1-9)Digital Subtraction Flash Cards in Color (1-9 Shuffled Twice)Digital Multiplication Flash Cards in Color (Ordered and Shuffled 1-9)Digital Division Flash Cards in Color (1-9 Shuffled Twice) Each book includes 162 digital arithmetic flash cards in color (where color is available). There are 628 flash cards all together. Each flash card is decorated with smiley faces and looks just like the flash cards depicted on the thumbnail image for the cover of this book. For the addition and multiplication books, the first set of 81 flash cards has the problems in order from 1+1 thru 9+9 or 1x1 thru 9x9. The first half of these books is designed for kids who are still memorizing their tables. The second set of 81 flash cards has the problems shuffled. The second half of these books is designed for kids who have tried to memorize their tables, and who need to test their mastery of it. In the subtraction and division books, the problems are shuffled in twice. The reason that all of the flash cards are shuffled (unlike our matching addition flash cards book, where the first set is in order and the second set is shuffled) is that kids who have already tried to memorize their addition facts should be able to learn the subtraction facts by understanding how subtraction relates to addition. For example, if you know that 6 plus 5 equals 11, by understanding what subtraction means, you can deduce that 11 minus 5 equals 6. Therefore, instead of putting the first set of subtraction flash cards in order, we thought that it would offer better practice for both sets to be shuffled. There is a similar relationship between division and multiplication. If your child is just learning the subtraction facts, but has already tried to learn his or her addition facts, we suggest that you try to explain that subtraction is very much like addition, but rearranged. If you add 3 to 6, you get 9. If you take 3 from 9, you get 6. 3 + 6 = 9. 9 – 3 = 6. A child who can make this connection only has to memorize one set of facts instead of two. Once your child understands that subtraction facts can be answered by rearranging addition facts, he or she will need practice in order to apply this concept successfully. The two shuffled sets of subtraction flash cards included in this book are designed to offer just such practice. Again, the relationship with multiplication and division is similar. Each flash card appears as its own picture on its own page. All of the flash cards come in First comes the problem flash card, followed by the corresponding answer flash card. The answer flash card reminds you what the problem was. So first you see the problem, and then you check your answer immediately. This eBook reads like a book. It is not a program or a game. It does not use a random number generator. The flash cards do look like ordinary flashcards (and they are in color and are decorated with smiley faces). The first half of this eBook has the flash cards in order to help memorize the times tables. The second half are shuffled to help test how well the times tables have been memorized. The shuffled cards will always appear in the same order.

About the author

Dr. Chris McMullen has over 20 years of experience teaching university physics in California, Oklahoma, Pennsylvania, and Louisiana. Dr. McMullen is also an author of math and science books. Whether in the classroom or as a writer, Dr. McMullen loves sharing knowledge and the art of motivating and engaging students.

Chris McMullen earned his Ph.D. in phenomenological high-energy physics (particle physics) from Oklahoma State University in 2002. Originally from California, Dr. McMullen earned his Master's degree from California State University, Northridge, where his thesis was in the field of electron spin resonance.

Dr. McMullen is well-known for:
• engaging students in challenging ideas through creativity
• breaking difficult problems down into manageable steps
• providing clear and convincing explanations to subtle issues
• his mastery of physics and strong background in mathematics
• helping students become more fluent in practical math skills

As a physics teacher, Dr. McMullen observed that many students lack fluency in fundamental math skills. In an effort to help students of all ages and levels master basic math skills, he published a series of math workbooks on arithmetic, fractions, algebra, geometry, trigonometry, and calculus called the Improve Your Math Fluency Series. Dr. McMullen has also published a variety of science books, including introductions to basic astronomy and chemistry concepts in addition to physics workbooks.

Dr. McMullen is very passionate about teaching. Many students and observers have been impressed with the transformation that occurs when he walks into the classroom, and the interactive engaged discussions that he leads during class time. Dr. McMullen is well-known for drawing monkeys and using them in his physics examples and problems, using his creativity to inspire students. A stressed-out student is likely to be told to throw some bananas at monkeys, smile, and think happy physics thoughts.

Dr. McMullen first published The Visual Guide to Extra Dimensions, Volumes 1 and 2, to share his passion for the geometry and physics of the fourth dimension. Dr. McMullen has coauthored a half-dozen articles on current and future collider searches for large extra dimensions.

In addition to writing and teaching, Dr. McMullen enjoys Scrabble, golf, and chess.
