Use the body... ask the children to demo the various angles and shapes using their body. they can be solo or have 2 to 3 members in the group. you can also play dumb charades through this - ask group 1 to give group 2 a shape to display and group 3 has to figure out what it is..
- Everyone participates
- It is a lot of fun as they grapple!
- Build the team feel
- They understand the properties 'kinaesthetically', an area sometimes difficult to bring in the math class
- Watch with hilarity as the ones not so flexible try to twist to show angle 90 degrees or bisector!
