Composing Triangles

Activity Instructions

Have students toss a bean bag onto the mat. Have them identify the type of angle where the bean bag landed. Then, challenge them: Can you form a triangle using that type of angle? They can work with two partners (lying down together to form the three sides) or use their fingers to model it. If the angle cannot be used to form a triangle, discuss why — and explore what makes a triangle possible.
