Classifying Triangles (GRADE 4 and GRADE 5)

In this video, I will teach students how to classify triangles. There are two ways we classify triangles! One way is by the length of their sides, and the other is the measurement of their angles. I will go over the vocabulary sides, angles, vertices, scalene, isosceles, equilateral, right angle, acute angle, and obtuse angle. Triangle classification is taught in fourth grade in MA and reviewed and refined in fifth grade in MA.
