Geometry Library

Martha Todd
Santa Rosa District Schools


Students write and illustrate books to make a class library of math term books. This is an excellent review for the FCAT math test.


The student writes for a variety of occasions, audiences, and purposes (for example, letters to persuade or request, humorous or suspenseful stories to entertain, instructions to inform).

The student uses appropriate geometric vocabulary to describe properties and attributes of two- and three-dimensional figures (for example, obtuse and acute angles; radius; equilateral, scalene, and isosceles triangles.).


-Book-making materials (paper, cardstock, stapler, brads or binders, markers, colored pencils, or crayons)
-Math textbook
-Cards of geometric terms (see file)


1. Run copies of the geometric term cards (see file), one card per child. (Some terms may be used more than once)
2. Gather book-making materials


1. As an introduction to geometry, or as a culminating activity, give each student a card with a geometric term on it. (file 1)
2. Students use their math books to write 5 facts about the term on the back of the card.
3. Students practice drawing the term, making it into a character. For instance, an acute angle could be Mr. A. Cute and he could have legs and a face.
4. Students write a story about the character, making sure they clearly and accurately explain the geometric term.
5. After the story has been edited by the teacher, the student uses the book-making materials to make the story into a book for the class library.


Books should include an accurate description of the geometric term, using at least 4 properties or attributes. The story should suit the audience (class members) and accomplish the purpose of clearly describing the character and term.


Additional terms could be used as appropriate for your classroom.
