Materials: Paper Plates, Pattern Blocks, worksheet

Goal: The angles of polygons complete 360 degrees to make a tessellation and tessellations have real world applications in flooring, quilts, etc.

Activity:

1. Have each person model angles with paper plates – acute angle, right angle, obtuse angle, straight angle.
2. Identify and name the 6 pattern blocks – green equilateral triangle, orange square, blue rhombus, tan rhombus, yellow hexagon, and red trapezoid and identify types of angles found in each.
3. Given the fact that a square has 4 right angles and an equilateral triangle has 3 - 60 degree angles, find the measures of all of the interior angles of all the pattern blocks and other shapes formed on the worksheet using the pattern blocks.
4. Find the pattern block that has twice the area as the tan rhombus. 
5. A hexagon can be made with 8 of the same pattern block. Which one?
