Digital Subtraction Flash Cards in Color (1-9 Shuffled Twice)

Digital Subtraction Flash Cards in Color (1-9 Shuffled Twice) (Memorize Arithmetic Facts Book 2)

This eBook includes 180 digital subtraction flash cards in color (where color is available). 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 eBook.

The 180 subtraction flash cards include two sets of 1-1 thru 18-9. All of the flash cards are shuffled.

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.

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 â€“ 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 eBook are designed to offer just such practice.

If your child has not yet tried to learn his or her addition facts, we recommend that you begin with addition, and use this subtraction book once your child has begun to master his or her addition facts.

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). Each subtraction fact appears twice. Both sets of subtraction flash cards are shuffled so that kids canâ€™t guess the answer based on a pattern. However, the shuffled cards will always appear in the same order.
