Maths Club
During the Spring Term, Year 4 and 5 pupils were part of a Maths Explorers Club; with the aim to help them solve problems, think logically and learn to test every possibility, not giving up if an answer is difficult to achieve.
Below are a few problems and games the children had to solve- can you solve them? Why not try playing a game against a friend (or your child!)

The coloured shapes stand for eleven of the numbers from 0 to 12. Each shape is a different number.
Can you work out what they are from the multiplications below?
Place each of the numbers 1 to 5 in the V shape below so that the two arms of the V have the same total.
How many different possibilities are there? What do you notice about all the solutions you find?
Can you explain what you see?
On a digital clock showing 24-hour time, over a whole day, how many times does a 5 appear? Is it the same number for a 12-hour clock over a whole day?
