Rectangles and Squares

Today we used pipe cleaners (30cm) to make rectangles with the same perimeter.  We made different rectangles and calculated the areas of each.  The biggest areas were found within the sauares.  The closer a rectangle gets to being a square, the bigger the area it contains.

We compared our results in small groups

And posted our work on the wall.

We extended the idea by trying different shapes with a 30 cm perimeter to try to find a shape that can hold more than a square.
