Are you still keen to solve Digit Dog’s challenges? Before clicking on the snowmen, have a look at them and think:
What do you notice?
What is the same about the snowmen?
What is different about them?

You will need Santa’s sleighs (download and print) and a set of Numicon® shapes. Match the shapes to the spaces on the sleigh.
How many shapes do you need?
Which shape will fit here…..?
Is the shape that goes here big or small? Bigger / smaller than a red one?
Can you take away one shape and put two in its place?
Which shapes are easy to find?
5. Start with the blank sleigh and ask learners to use the Numicon shapes to cover it in any way they can.
How many different ways can you do it? Compare your sleigh with your friend’s. What’s the same and what’s different?
You weren’t allowed to use the same shape more than once? How many ways can you do it? Is this more difficult? What are you thinking?
Can you use one shape repeatedly to cover the sleigh? Which shapes will work? Which won’t? Why?
What is the fewest number of shapes you can use? The most?
You use only odd shapes? Only even?
