Today for math's we had to make 3D shapes out of skewers. I made a Square based Pyramid.
A Square Based Pyramid has 8 edges so you need 8 toothpicks.
It also has 5 vertices so you need 5 balls of blue tack.
First you need to get your biggest ball of blue tack and stick 4 toothpicks in strait across from each other.
Then you need to get your other 4 toothpicks and make a square using your blue tack to stick them together. Now connect the square and the first piece you made together and you have a square based pyramid.
These are other shapes I made.
Octahedron
Cube
Tetrahedron
