After checking our measurement homework - which had been done very well by all those who listened carefully - we moved on to look at the
perimeter of flat shapes. The perimeter means the distance all the way round the outside of the shape. If we were a tiny ant, we could start at one corner and crawl all the way along each side, back to the corner where we started. The distance we have crawled is the perimeter.
Finally we drew rectangles that had a perimeter of 20cm. We found five ways to do it using whole centimetres. Have fun explaining to your family why the green one is still a rectangle, even though it is also a square!
