Digging Into Number

These tasksĀ give you the chance to dig deeply into maths, particularly number and calculation. The way to a solution is not obvious, so you will need to be prepared to explore, to make use of your creativity, and to explain your ideas. The deeper understanding you gain will make it all worthwhile!

The last day for sending in solutions is Monday 11 October.
