This was a fun center idea for students to determine Obtuse, Acute, and Right Angles. The kids taped up some old tables outside in the common space to create intersections of different sized angles. Next, in small groups the class took turns labeling each angle with it’s corresponding name based on it’s size.

A few days later, once we introduced angle degrees and measurement using protractors, the kids were again able to use these tables in small groups, this time to measure how big each angle was. The tape provided an extra challenge, as the kids figured out they needed to measure from the inner tape line in order to get an accurate measurement.
