These cards can be used in so many ways! They can be used as flashcards, task cards, or at math centers. They can even be sent home for kids to practice with parents. They cover all of the tens facts (0+10, 1+9, 2+8, etc.) with the missing addend in both places and missing sums. Each card includes a sentence starter, "The missing addend is ___" or "The sum is___" to provide scaffolded support for students to use math vocabulary/academic language. These can be printed on card stock and laminated to be more durable, and can be used as write and wipe cards if desired.
