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...

As a reference sheet for types of triangles, this worksheet would be good for students to keep in their binder or to take notes about; however, it would need to accompany an existing lesson as there is no activity beyond basic...

In this classifying shapes using Venn diagrams worksheet, students draw examples of isosceles, right, and equilateral triangles in the proper sections of the first graphic organizer. They draw polygons, both regular and quadrilaterals,...

In this formulas worksheet, students write the area, perimeter, and volume formulas of 17 2D and 3D polygons.  Students list properties of various types of triangles and the metric conversions for metric units.

In this problem solving strategy worksheet, students complete a graphic organizer to help solve a problem. Students complete 4 sections: understand, plan, solve and look back. Houghton Mifflin text referenced.

In this math worksheet, students look for the properties related to each shape and then fill in the graphic organizer with the categories needed.
