This set of task cards help students review the key concepts from Unit 1 of 4th Grade EDM. Two ways to use them:
1) Put one on each table face down - students try to beat the teacher solving each one as they walk around the room. They solve each one on a sheet of paper.
2) Make a set for each small group in the class - they take turns turning one over - solve it - and that person gets a point.
This is a great review activity once the concepts are covered and you want to do some review.
