Students practice finding the central angle in circles with this matching card set. Included are 20 pairs of matching cards. Half the cards have a circle, with central angle defined and the other half have an expression for the angle measure. Students will have to use their knowledge of angle relationships in a circle to set up an equations and solve.
You can use as a sorting activity with pairs or groups, as a warm-up, exit cards, or several other activities. I have my students work in pairs and make posters of the matching pairs with a writing activity in their notebook of their strategy in solving the problems.
