Math Activity: Pattern Block Angles

Purpose: Explore lines of symmetry and rotational symmetry.

Materials: Pattern blocks or pattern block app, paper, color

  1. Math Learning Center Pattern Blocks Links to an external site., nice protractor, shareable
  2. Toy Theater Pattern Blocks Links to an external site., dragging feels real

Directions:

First, identify the symmetries of each pattern block, then use the pattern blocks to create various other symmetric figures.

Part 1: Identify the symmetries of each pattern block below. Draw sketches and/or write descriptions for each.

Block Lines of symmetry Rotational Symmetry
pattern block hexagon
pattern block trapezoid
pattern block rhombus blue
pattern block triangle
pattern block square
pattern block rhombus light

Part 2: Be more creative and create new figures from the pattern blocks.

Figure and name Lines of symmetry Rotational symmetry

Example: Equiangular hexagon

equiangular hexagon with 2 lines of symmetry and 180 rotational symmetry

 There are two lines of symmetry, vertically and horizontally cutting it in half. If you rotate the figure 180 degrees, then you get the same shape. That is the smallest angle for rotational symmetry.
