Position

One of the key ideas associated with place value is that the position of a digit affects its value. These activities support children in understanding this idea and form part of our Number Sense and Place Value Feature.

Two-digit Targets

Age 5 to 7
Challenge Level Yellow star

You have a set of the digits from 0 to 9. Can you arrange these in the five boxes to make two-digit numbers as close to the targets as possible?

Five Steps to 50

Age 5 to 7
Challenge Level Yellow star

Use five steps to count forwards or backwards in 1s or 10s to get to 50. What strategies did you use?

6 Beads

Age 5 to 7
Challenge Level Yellow starYellow star

If you put three beads onto a tens/ones abacus you can make the numbers 3, 30, 12 or 21. What numbers can be made with six beads?

Largest EvenLive

Age 5 to 11
Challenge Level Yellow star

How would you create the largest possible two-digit even number from the digit I've given you and one of your choice?

Which Scripts?

Age 7 to 11
Challenge Level Yellow star

There are six numbers written in five different scripts. Can you sort out which is which?

Nice or Nasty

Age 7 to 14
Challenge Level Yellow star

There are nasty versions of this dice game but we'll start with the nice ones...
