Estimate the area of shapes a-d. Don't forget to include the label "unit squares" to your guesses! What is challenging about these areas? How can you find the area of a shape with a diagonal in it? Then find the actual area using the unit squares. Right click and turn on the grid tool to help you.[br][br]When you finish, use the bottom three rectangles to find three DIFFERENT shapes with an area of 8 unit squares that also include AT LEAST ONE DIAGONAL. Try to find a strategy for creating the different areas.
