This book/presentation is about triangles. Throughout the book the fact that all triangles have three sides, three angles, and three vertices is repeated. The book discusses sides, angles, and vertices. The book also talks about the special combinations of different angles and sides, and how the result is a different looking triangle with a special name. The contents also include 18 vocabulary words that revolve around the triangle theme and simple definitions geared to the elementary school student . Also a page that involves a hands on activity for the student is included.
I created this as an alternative to worksheets. There is a page to cut out and create manipulatives. You may choose to keep these in a folder/envelope and use for a while, or paste and label onto another sheet as a formative assessment.
