March Challenge - Years 5 & 6

Imagine you have 25 beads.

You have to make a three-digit number on an abacus.

You must use all 25 beads for each number you make.

How many different three-digit numbers can you make?

Write them in order.

Here are some examples of how a place value abacus works.  These are not possible solutions to the problem though, as the first example only uses 8 beads and the second only uses 17 beads.

           

 Solutions are to be completed by Wednesday 30^th March.  Please post them into the Maths Challenge Box in the picture book library.
