Find my complement, Find my supplement
In-class activity that works well when the terms complementary and supplementary are introduced. Teacher hands out a small card to each student and then teacher instructs students to get up and find their complement in the room. Also a good way to partner students up for other activities. This activity involves basic Algebra as well. For example, one student may have a card that says 4x + 70 and they would have to find 20 - 4x. There is a set of cards for complemenary and supplementary.

Set Complement Scavenger Hunt
Scavenger hunt testing students' abilities in set complements and set cardinalities. Students will be able to start at any of the sets #1-#10. They will progress to their next set by answering what the previous set cardinality was. This will tell them which set will be their next destination. This allows different groups of students to start at different points and ensure that they all see each of the sets included.

Fast Facts Review: +0, +1, +2, +10, Doubles, and Complements of 10
In order to increase students' confidence in addition facts, I always started by teaching one trick at a time. I began with +0, then +1, then +2, then doubles, and then complements of 10. Once students know those tricks, they can simply memorize the other facts. Here is an easy sheet to review JUST these fast facts.
