Need a simple way to differentiate? Want to incorporate writing into math? Enjoy using graphic organizers? Want your students to write a nonfiction book using all book parts in math? Then, you should use this product to assess students on what they know about geometry. Three formal graphic organizers are included. The book covers plane figures, solid figures, and angles. The book is 15 pages. I have also include a rubric to assess the book. I have created and used this resource, and students truly enjoy it. I start off my unit sharing THE GREEDY TRIANGLE. Then, I explain that we will write a book similar to the one written by Burns; however, I require it to be non-fiction.
