Wednesday - Maths 

Today you have a pattern problem - can you find all the combinations? 


Ukaliq was making necklaces to sell at the school fair.

She decided to make them very mathematical.

Each necklace was to have eight beads, four of one colour and four of another.

And each had to be symmetrical, like this.


How many different necklaces could she make? 

Can you find them all?

How do you know there aren't any others?

What if she had 9 beads, five of one colour and four of another?

What if she had 10 beads, five of each?

What if she had 12 beads, using 3 different colours?
