These cards can be used as a whole group, small group, or math center activity. It is just like the game memory, only with math vocabulary. Words have been broken down into separate units, mostly to meet separate CCSS needs.
There is a blank recording chart at the end of the document for students to record the definitions of each vocabulary word. There is also an answer sheet included.
These cards can be used with any EngageNY unit, as well as any unit where you are covering multi-digit whole number and decimal fraction operations.
