Exploring Triangles

Display your geometry genius by creating a poster of popping triangles.

• 1.

  Find out about different kinds of triangles, including right, isosceles, scalene, and equilateral triangles. Identify characteristics of each triangle.

• 2.

  Use a ruler and Crayola® Colored Pencils to make samples of each kind of triangle. Decorate triangles with colorful patterns, then cut out with Crayola Scissors.

• 3.

  Cut and fold small strips of paper in fourths to make tabs to attach to the backs of each triangle. Glue one end to the other with a Crayola Glue Stick. Apply glue to the outward faces of the tabs to attach triangles on poster board.

• 4.

  Use colored pencils to label each triangle on the poster board. Add descriptive captions identifying characteristics of each triangle. Draw arrows pointing out particular angles typical of specific triangles. Design a title for your poster using block lettering and bold colors.

Benefits

• Children learn about the characteristics of various types of triangles.
• Students draw triangles.
• Students use appropriate vocabulary to describe characteristics of and identify the names of triangles.

Adaptations

• For each triangle, cut out a sample triangle template, then trace it to make a pattern picture, coloring in triangles with colored pencils. Try to make each traced triangle border on another triangle. Display in a gallery of triangles.
• Create colorful study cards. Make a bright triangle border around each index card. Write notes about the triangle's characteristics in the center of the card in colored pencil.
• Students and their parents search for samples of each of the different types of triangles at home and in their neighborhood. Make a chart showing the variety of triangles found.
• Younger students and those with special needs may need to trace templates of basic triangles. Provide assistance with scissors as needed.
