This morning we were exploring regular and irregular polygons.  Firstly we had to recall what a polygon was (a closed 2d shape with straight lines) and then discover what made a polygon regular (all sides the same length and all internal angles the same size).  Armed with that knowledge we tried making different shapes using equilateral triangles and then labelling the properties we could identify.

Today we were developing our problem solving skills by exploring different activities relating to area.

First we had to investigate what happened when a shape was doubled in size.  We could see that when it was a square, the larger shape was then made up of 4 of the original squares.  Was this true for other shapes? 
 

Secondly we were challenged to cut out 9 different sized squares, with sides ranging from 1cm to 18cm, and see if we could fit them all together into one rectangle!

We have been learning how to calculate the area and perimeter of different shapes.  Today we explored how to estimate the area of some tricky shapes, including our own hands!
