Corresponding Parts of Similar Triangles
Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

Similarity
Eighth graders understand that proportional enlargement of shapes doesn't change the angles of those shapes. For this similarity lesson, 8th graders complete exercises to create enlargements of shapes and understand similar shapes.

Dilation
Open up your pupils' eyes and minds on dilations. Scholars perform dilations on a trapezoid on the coordinate plane. They compare the image to the preimage and develop generalizations about dilations.

What Can Tree Rings Tell Us About Climate?
Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

Layering the Air
Students study the layer of the atmosphere. In this lesson on the atmosphere, students discuss the composition of the air around us and how the atmosphere was formed. Students create a scale model of the layers of the atmosphere.
