Challenge Level

Why do this problem?

This problem links English and mathematics, and will help children become familiar with numbers that are, and are not, factors of $12$. You can also focus on learners' justifications and explanations of why certain arrangements of letters work. You may find this sheet of 'blanks' useful.

Key questions

How many spaces for letters do you have?
Where do you find the first letter?
What could the next letter be? And the next?
When you're using your own word, what happens if you put the letters in every second space ... every third space ... every fourth space?
Can you explain why?

Possible extension

Learners can be encouraged to find all the possible ways of arranging one word. How do they know they have them all? They could also try using words with a different number of letters, and changing the number of sections in the circle. Can they move the letters by any number of spaces?

Possible support

Some children will find it helpful to start by writing the word continuously round the circle.
