Cutting shapes.

Figure out different ways to cut out shapes from a quadrilateral.


Supplies: paper, pencil, scissors and a straight thin object (pencil or ruler). 

What to do: 
We start with a non-convex quadrilateral like in the picture. With a single straight line cut (your child can place the straight rod on the paper instead of cutting), can you get
(a) two triangles (3 ways)
(b) three triangles (1 way)
(c) a triangle and a quadrilateral (6 ways)
(d) a triangle and a pentagon (3 ways)
(e) two quadrilaterals (2 ways)
