Students explore the origin of tangram. In this algebra lesson, students form different shapes and figures using tangram. They solve for the area of different shapes without using any geometric formulas, but the idea of tangram being put...

In this shape lesson, learners cut out tangram shapes and create different pictures with them. They look at 3-D shapes as well. There is a nice, hands-on component built into this lesson.

Students perform transformations and translation on a coordinate plane. In this geometry lesson, students move shapes around on a graph identifying translation, image, and transformation. This lesson has an interactive part online that...
