Finally a set of flash cards that is pre-sorted. No more going through stacks of cards to find the combinations you need.
Sets included are:
Sums to 10
When printed double sided, the back of each set has a different background. Also, each card contains the name of the set in case printing both sides is not feasible.
I have included two versions. The first is the flashcards without the answers. The second is the flashcards with the answers on the back.
