This lesson explores the perimeter of shapes made from pentominoes, and offers students opportunities to work systematically and construct reasoned arguments.
In this lesson, we explore the internal angles of regular polygons, and how they decide whether polygons can me joined together without any gaps.
This task uses tetrominoes as a context for exploring enlargements (dilations) and scale factors. Which “rep-tiles” can your students create?
