Identifying and Classifying Solid Figures
Learners identify and classify solid geometric figures. In this geometry lesson, students bring in objects that look like solid shapes and identify their attributes. Learners identify the number of surfaces and faces on each figure.

Examples of Dilations
Does it matter how many points to dilate? The resource presents problems of dilating curved figures. Class members find out that not only do they need to dilate several points but the points need to be distributed about the entire curve...
