Showing Results for triangles

Classifying figures by features is a fundamental geometry skill. Use this lesson plan to teach your students how to categorize triangles by internal angle types.

You'll see angles from every angle! Students will describe and compare different angles they see in everyday situations. Use this lesson on its own or use it as support to the lesson Classifying Triangles by Internal Angles.

Adding fractions with unlike denominators just doesn't work like it does when the denominators are the same. Let's make it work! Students will add fractions with unlike denominators with sums between one and two.
