Solutions to Week 6 – Counters

Hello everyone,

Thank you to everyone who had a go at last week’s maths challenges.

 

Here are some of the solutions:

First Challenge

This involved biscuits and decorations. Rory, in Year 1, used wooden blocks and Lego to solve this.

And here is another classmate using paper, sparkly pipe cleaners and REAL chocolate buttons to give us her solution. Yum Yum!

Arlo, Year 2, found the solution too. He knew there was only one biscuit with all three decorations on it.

But my question is WHY does biscuit 12 have all three decorations of icing, a cherry and a chocolate button?

Well it’s all to do with factors! Thank you Rory – you picked this up too.

There is one biscuit with all three decorations and that is because 12 is in the 2, 3 and 4 times table. Take a look:
