Math Mammoth Geometry 1 covers all the typical geometry topics for grades 4-5: angles, triangles, quadrilaterals, other polygons,area, perimeter and volume.

The PDF version of this book is enabled for annotation. This means that if you prefer, your student can fill it in on the computer, using the typewriter and drawing tools in Adobe Reader version 9 or greater.

The problems in this book involve lots of drawing. Geometry is a hands-on subject, and many children like that. Moreover, drawing is an excellent means of achieving the conceptual understanding that geometry requires. Exercises marked with the notebook symbol are meant to be done in the student's notebook or on blank paper.

The study of geometry is also full of new vocabulary. I encourage the usage of a geometry notebook, where students will write every new concept or term, and draw a picture or pictures and text to explain the term. That will help them to remember the terms better, and most children will like creating a book of their own. The students can also do the drawing exercises in this book.

### The lessons in the book

First we review the area and perimeter of rectangles (as taught in third grade). Then the students are introduced to angles, and learn about acute, right, obtuse, and straight angles. Students learn how to measure angles with a protractor, draw angles, and estimate some common angles.

After angles, we study parallelograms and different kinds of triangles (acute, obtuse, right). We also review polygons and then go on to a lesson about circles. Students learn the terms circle, radius, and diameter, and learn to draw circles and circle designs using a compass.

Then we go on to classify quadrilaterals and triangles. There are seven types of quadrilaterals to learn about, and now students classify triangles both by sides and by angles.

The last section of the book deals with area and perimeter of rectangular shapes, and volume of rectangular prisms. I have also included a lesson for problem solving, and two review lessons.

You can use most of the geometry videos on this page in conjunction with Math Mammoth Geometry 1.

### Area versus Perimeter

We take a look at geometry problems that involve both area and perimeter of rectangles. For example, the area of a square is given, and perimeter is asked. Or, vice versa: the perimeter of a square is given and the area is asked. Then I solve two problems where some side lengths and other info is given, and either perimeter or area is asked. Lastly we look at this open-ended problem: If the area of a rectangle is 18 square centimeters, what can its perimeter be?

## Feedback/ reviews

I teach special education in the public school system, and just recently downloaded and have taught from Geometry 1. My middle school students love the hands-on approach and have really begun to explore the meaning of geometric terms and measurements through the use of this book. We have expanded it to include a project whereby they create designs using angles, arcs, and circles. We will be using these colorful designs to learn even more about measurements and geometric figures in conjunction with some of the lessons from the book. Thanks so much for opening up this opportunity to make math useful and fun for these students who often view math as a painful process they have to endure! Their attention to their drawings is truly amazing! We have all enjoyed the process!

From a tutor who has used Geometry 1 with 3rd and 4th graders:

I used, and continue to use your Geometry 1 workbook as my main geometry curriculum. I use Math Advantage as a basis for my math lessons but skip around and supplement it greatly.

My son enjoys the Geometry workbook. I appreciate that you have included area, perimeter and volume in the book. Many books categorize those topics as measurement, but I've found that it is easier to teach them with geometry. The curriculum is more in depth than most for the recommended grade level.

From a parent who has used Geometry 1 with a 4th grader:

This book is quite good for building fundamental knowledge for children who are learning geometry. This is more than enough, comparing mine when in same grade 30 years ago.

From a teacher who used Geometry 1 with 7th graders:

My students enjoyed the review!
