This activity focuses on the types of triangles- scalene, isosceles, equilateral, right, acute, and obtuse. There are a few questions that ask the student to measure a line segment on the triangle. This helps the student understand WHY the triangle is the type that it is. I used this in pairs, but it can be used in stations, learning centers, or even independently. Just copy the 2 pages of triangles and have the students cut them out, or you could cut them out and laminate them so that you can use them over and over. You could even have students write the types of triangles on each one and put into their interactive math notebook.
