The Angles of a Triangle

Why tell a kid the rules of a triangle when they can discover them!?

This activity contains 5 student videos and 3 printable worksheets that you can share directly with your students.

Less overwhelm for teachers. More delightful thinking for students.

Each lesson includes videos, worksheets, and a teacher guide. Your teachers press play. Students do the thinking. No training needed.

It’s like having a second teacher in my classroom.
