# Playing with Number

## Playing with Number

We know it's important for children to play around with numbers, big and small, as this exploration can lead to a deeper realisation of the way the world of numbers fits together.  We've chosen some tasks that are exploratory whilst supporting understanding of the four calculations.

### One Big Triangle

##### Stage: 1 Challenge Level:

Make one big triangle so the numbers that touch on the small triangles add to 10. You could use the interactivity to help you.

### Noah

##### Stage: 1 Challenge Level:

Noah saw 12 legs walk by into the Ark. How many creatures did he see?

##### Stage: 1 Challenge Level:

Ranging from kindergarten mathematics to the fringe of research this informal article paints the big picture of number in a non technical way suitable for primary teachers and older students.
