Sorting shapes and making shapes from shapes

Sorting shapes in a Venn diagram

Building on from our work with triangles we have been thinking about quadrilaterals. Did you know that a quadrilateral is 'a polygon with four sides and four vertices or corners'. We had to think carefully about triangles and quadrilaterals when we were sorting their different properties. We are all able to remember the isosceles triangle, two equal sides and two equal angles, really well now after one of us called it an isausageles! We all laughed at that and it has helped us to remember it. It just sounds so tasty.

Combining triangles

We have also been using equilateral triangles, three equal sides with three equal angles of 60 degrees, to make a range of different shapes. It was quite a challenge and as Dr. Suess says, "We puzzled and puzzled until our puzzler was sore." Working with a partner helped us to solve the tricky problems we were given.

This one really got us thinking!
