These task cards can be used as a review or for additional practice. You can use them in a math center as a station or you can use them as a whole class search the room activity. Each task card asks students to use one of the many strategies (number bond, tape diagram, number line, totals below, chip model, etc) from Eureka Module 4 (2nd grade) to solve the problem. Some task cards ask students to find the sum and others ask students to find the missing addend. An answer sheet is included.
