A walk is made up of diagonal steps from left to right, starting at
the origin and ending on the x-axis. How many paths are there for 4
steps, for 6 steps, for 8 steps?

##### Age 14 to 16 Challenge Level:

How many ways can the terms in an ordered list be combined by
repeating a single binary operation. Show that for 4 terms there
are 5 cases and find the number of cases for 5 terms and 6 terms.

##### Age 14 to 16

The tangles created by the twists and turns of the Conway rope

##### Age 14 to 18

An introduction to the binomial coefficient, and exploration of some of the formulae it satisfies.
