Our solutions

Fractions in a box

 

This week's challenge required the children to use what they knew about fractions and square numbers to try and solve how many discs (of a certain colour) could be fitted into the box. Information was given but amounts were not. Here are our solutions. 

Fractions in a box

Make 37

This week's challenge had the children really puzzled, with questions such as 'How can I make an odd number answer out of 10 odd numbers?'

The children had a trial and error system of using exactly 10 numbers from the list 1,3,5 or 7 to make the total 37.

After many false claims of 'I've done it!' to be checked as 'your total is 38 or different , to you've used too many digits' we had a look online to see the solution. 

Here are our explanations of our workings out.

A Puzzling Cube

 

For this week's challenge the children had to work out the net of a cube with only certain views of its faces. 

Some children chose a hands on approach of sticking the faces on a cube and testing the positions. While other children were visualising the cube being folded and unfolded, as well as turning it to check the patterns matched the criteria.

An Egg problem

This week's task required the children to work systematically but also work backwards to find missing amounts.

Money Bags

This week's challenge was aimed at using logical reasoning to find the amount of coins put in each bag. The children had to prove that they could pay for any amount between 1p and 15p by just using a bag with a set amount of pennies in.

Follow the numbers

 

This week's challenge was to try and spot patterns in numbers after following a set rule of adding and multiplying. 

The children were then challenged to create their own set of rules and see if they could make a pattern emerge.

Trebling

This week's challenge required using times table facts and the knowledge of how to exchange when calculating to solve the coded question. 

Each letter represented a number and would only make the answer correct if all the above skills were used.
