If you are looking for some online math manipulatives, Mathigon is a game changer! My students love all the tools to represent and show your thinking. You can also save a template to get Ss …

Polypad provides a set of digital manipulatives that can be used instead of or alongside physical manipulatives to support students’ development of key mathematical concepts in shape, …

Even though these tools look very primitive, you can draw a great number of shapes with them. This became almost like a puzzle game for mathematicians: trying to find ways to “construct” …

In this and the following courses, you will learn about many different tools and techniques in geometry, that were discovered by mathematicians over the course of many centuries.

Introduction, Degrees and Radians, Tangents, Chords and Arcs, The Circle Theorems, Cyclic Polygons, Spheres, Cones and Cylinders, Conic Sections

Invite students to make some shapes of their own by joining together two different pentominoes (but they can use the same pentomino more than once in different pairs).

Challenge students to come up with a mathematical way, using their knowledge of interior angles, to convince you whether the shapes fit exactly or not. They could annotate the arrangements …

Automotive Design From the shape of the body to the engine, the materials to the colors, math touched nearly everything in car design.

The goal is to make objects out of one or more sheets of paper, without any additional tools like glue or scissors. You can create incredibly beautiful and impressive designs – all of these …

Geometric shapes are everywhere around us. In this course you will learn about angels, polygons, tessellations, polyhedra and nets.
