This handout includes descriptions and examples of equilateral, isosceles, and scalene triangles, as well as right, acute, and obtuse triangles. The short description and example show students how to identify the different shapes.
After explaining the different triangles to the students, have them explore around the school looking for as many triangles as they can! In the boxes they should draw a picture of the triangles they see as well as classifying them with as many names as possible! (eg, acute isosceles).
Students will love this lesson because it gets them out of their seats and moving around the school! It also allows them to visualize geometrical shapes in everyday life, which they can take home with them!
