It makes sense to only offer addition flash cards 0 to 9 (most sets go to 12). But subtraction flash cards really need to be 0 to 18. Trend recognizes this, but you have to purchase the 0 to 18 flash cards in two sets. This set covers 0 to 12. You can do a search: "Trend subtraction flash cards" to find the 13-18 set.

What I like about these flash cards is they are plain-vanilla. No frills, no color, one problem with the solution on the other side.

Every combination of problem is offered. While learning, I generally "group" my math facts by families....i.e. 9-7 on one card, and then 9-2 on the next. If my son or daughter gets stuck, I give them a hint by showing the next card. It works quite well to jog memory, and to assimilate family facts. Then, after a set of fact families are learned, I mix them up completely.

I bought Trend's addition and subtraction flash card sets. The addition ones are very straightforward you get every addition combination involving 0-12, from 0+0=0 to 12+12=24. Saying that subtraction cards include "0-12" is a lot less clear, so let me help you understand what's included here. You get a set of subtraction cards that follow these rules:

The minuend (first number) ranges from 0-24.

The subtrahend (second number) will not exceed 12.

The difference (answer) will not exceed 12.

Problems that would result in negative answers are not included, so the card set forms a sort of triangle/pyramid where you start with a single card (0-0), go up to a 13-card series (12 minus 0-12), then shrink back down until you are back to a single card (24-12). Here's an example, of course a bunch of stuff is omitted but hopefully you get the idea.

0-0=0

1-0=1,1-1=0

2-0=2,2-1=1,2-2=0

...

12-0=12,12-1=11,...,12-11=1,12-12=0

...

22-10=12,22-11=11,22-12=10

23-11=12,23-12=11

24-12=12
