Young scholars investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

Pack the instructional activity into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and...

Students hunt for hidden geometric shapes and compare the properties of various shapes. In this geometry lesson, students play a game of finding squares, circles, rectangles, and ovals that have been hidden around the classroom. Students...
