Ever tried an Arithmagon? On your left you will see an example of one. What you have to do is fill in the circles so that their sum is the number in the square. Therefore in the triangle you have 3 numbers and 3 sides, you must fill in the gaps so that the circles on each side combine to make the number in the square.
Now that you've seen an example, try this one on the left for yourself! Ask an adult to check your answers when you are finished to see how well you did. The great thing about arithmagons is that they help you improve your mental maths whilst also engaging the artistic and creative side of brain, plus they're fun, best of luck everyone! It took me a while to figure it out!
