Shapes

In Maths, we have been focusing on 2D & 3D shapes. We have also looked at symmetrical patterns and cross sections.

We created our own symmetrical pictures using pattern blocks. We placed a ruler on the floor as a line of symmetry and it really helped us learn about symmetry of 2D shapes.

 

Can you find any symmetrical items in your home? How do you know they are symmetrical?
