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 pairs: 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.
