This is a set of 20 task cards designed to give students practice with complementary and supplementary angles. Students do not need to be able to use protractors in order to use these cards, instead they must use reasoning (or addition) to find the angle pairs or the measurement of missing angles. All necessary angles are labeled with their measurements.
I made these to use with above level fifth grade math students. For some reason, this skill seems to cause kids trouble and I've been trying various approaches to get them to be able to "see" complementary and supplementary angles. I typically run off several sets of these cards and have kids work in pairs to solve the problems while I'm working with another group. They would also work well for a math center. The answer key is included.
This is a 7-page PDF file that includes 5 pages of various task cards (4 per page), a 1 page recording sheet for students, and a 1 page answer key.
