This is a missing addend scoot. Students will read the problems on the task cards and find the missing addend for each problem. Teachers will place the cards, in order, around the room. Students will then rotate through the cards, writing the answers on the response sheet. I have provided two types of response sheets. One response sheet has the problems listed with a space provided for the students to write the missing addend. The other response sheet is blank and students will have to write the problem, filling in the missing addend.Teachers should choose which response sheet students use. An answer key has also been provided.
