* They illustrate the relationships between numbers as well as the inverse relationship between addition and subtraction.
* Students work with these 5" x 5" activity cards to build fluency, and gain number sense at the same time.
* Teachers can use the cards with groups, in pairs or with individuals.
* Answers are on the flip side of the card, so it's easy for students to check their own or each other's work.
