Triangle Edges
Old Notes
This problem lends itself very well to practical exploration using
sticks or cuisenaire rods. Having this "hands-on" experience will
help children to realise the need to be systematic and develop
their own recording system.
Possible triangles:
3, 3, 3
4, 4, 4
5, 5, 5
3, 3, 4
3, 3, 5
4, 4, 3
4, 4, 5
5, 5, 3
5, 5, 4
3, 4, 5
Total = 10
