These task cards can be used in many ways! I use them for centers, scoots, whole group, and addition and subtraction sorts. I created them for second grade covering the 2.OA.1 standard but could also be used in third or fourth grade for review.
There are 30 word cards that I use for a scoot. There is also an answer sheet and a modified answer where the student chooses the synonym or synonyms from a list of four rather than giving a synonym for the word on the card.
