These fun, hands-on and interactive activities will help your children and students master geometry terms and concepts. Students will have a blast with these geometry art projects, online geometry games and geometry books.
After students have gotten a grasp on different types of polygons, have them make some geometry people. All that is needed to do this activity is different colors of construction paper, scissors and markers or crayons. Give guidelines as to how many geometry shapes children should use. Thus, for young children, a good guideline might be five shapes and for older children say ten shapes. Encourage them to use more complex shapes like trapezoids, octagons, pentagons and parallelograms. Shapes can be turned in any way. The final direction is for children to write a simple definition on the back of the shape. This is one activity where it is good to show an example. An example of a geometry person may include a circle for a head, rectangle for a torso, octagons for hands, parallelograms for legs and trapezoids for feet. Ovals can be used for eyes and a triangle for a nose.
Try some of these online polygon sorting and matching games from Johnnie’s Math Page. In addition, there are four pages of online geometry games at gameaquarium.com. There is everything from simple polygon games to coordinate grids and area. Kids can do this during their computer rotations during math groups.
This is a good activity to do when studying the different types of triangles: equilateral, scalene and isosceles. Give each student a sheet of construction paper and other construction scraps to make the triangles. Using colored construction paper, students should cut out the different types of triangles. Each triangle should be given a name. Try things like mama isosceles, papa scalene and baby equilateral. Short definitions of each should be written under each triangle also. Try three equal sides for equilateral, two equal sides for isosceles and all sides different for scalene. Then, give kids yarn and fun things like googly eyes to personalize each triangle. Review the different types of triangles at mathisfun.com.
There are tons of fun picture books that explain geometry concepts. The Greedy Triangle, Sir Circumference and the First Round Table and Mummy Math: An Adventure in Geometry are all great books. The Greedy Triangle by Marilyn Burns features a triangle that wants to be more complex. Thus, it changes into different shapes. This book is geared towards primary elementary children and helps them learn their shapes. Sir Cumference and The First Round Table by Cindy Neuschwander exposes children to different geometry terms in a fun story about King Arthur and his knights deciding what shape for the table to be. This book is good for kids nine to twelve. Mummy Math: An Adventure in Geometry by Cindy Neuschwander teaches kids about geometric solids through an adventure in Egypt. All three of these books are available at amazon.com.
