Building Shapes

SQUARE TO CUBE:

• Start of with something simple – like a square.
• Take four short drinking straws and four marshmallows. If you can’t find short drinking straws just cut the big ones in half.
• Next stick one straw into each marsh mallow. Now place them on a flat surface in a square and when you’re happy they’re positioned correctly, stick the other ends of the straws into the marshmallows.
• Do you have a square?
• Good, now make another one and join them together with another four short straws to make a cube!

TRIANGLE TO PYRAMID:

• Take three marshmallows and stick a short straws into each.
• Lay them on a flat surface to make a triangle.
• When you’re happy they’re in the right places, stick the other ends of the straws into the marshmallows. Presto! You have a triangle.
• Now make a second triangle using the top marshmallow of the first, so that you have two triangles joined at the top.
• Now, join the bases of the triangles with another two short straws and you should have a nice marshmallow pyramid!
