Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...

This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...

The problems on this quiz give descriptions and properties of specific triangles. Students are expected to read the information and identify the triangle that is being described.

In this exercise, students practice recognizing triangle types. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.
