Marshmallow maths

For Maths week we did lots of work on 2D and 3D shapes....
...with marshmallows and toothpicks.

We made triangles, squares,

pentagons,

hexagons,

We changed our hexagons into rectangles and squares.

We figured out how to make cubes. We found that these cubes were not very strong.

Here are the numbers of marshmallows and toothpicks you would need to make these shapes.

We made triangular prisms,

and pyramids (square pyramids and triangular pyramids).  These were much stronger than the cubes we made earlier.

We also had time to make our own structures (rockets, giant cubes, stars and other interesting shapes).
