Teachers, save “LEGO Perimeter and Area of Irregular Shapes” to assign it to your class.

Use LEGO to create a shape. Take a photo of your shape. Add a label for the heading ‘Perimeter and Area’ Use the drawing tool to write the measurements for each edge of your shape by counting the number of dots on the LEGO pieces. Add a label to write the formula for working out the perimeter (adding each side together) and work out the answer. Use the drawing tool to break your shape up into regular shapes (squares or rectangles). Write the formula for working out the area inside each regular shape (length x width). Add a label to write the formula for working out the area (length x width for each shape and add the area of each shape together), and he answer.
