This activity gets kids up and moving. I have all students stand up and move towards the middle of the room. I put the signs up around the walls of my classroom for isosceles triangles, equilateral triangles, scalene triangles, obtuse triangles, right triangles and acute triangles. I read the information for a triangle. The information about the triangles focuses on the side length or angle measurements. Without talking, the students move to the area where the answer is posted on the wall. Then I pick a student to explain why they are standing there. Then students can discuss or defend their location. This activity also allows teachers to have conversations about acute triangles and equilaterals triangles. I put the correct answer based on the information given about the side lengths or angles. As a teacher we still talk about how equilateral triangles are also acute triangles because they could never be obtuse or right. This conversation is usually started by the students.
