Playground Arithmetic

Today, my group had fun writing arithmetic questions for the rest of school to solve.

4s

In Maths today, Mr Raine’s, Mrs Marshall’s and my group took part in an exciting investigation called 4s. We had to use only the number 4 to make the numbers 1-20, e.g. to find 16, you could calculate 4 + 4 + 4 + 4.  or 4 x 4.

If you would like a go, you could try a simpler version where you can use as many 4s as you need. However, a real challenge is to have to use four 4s in each calculation, e.g. to make 8 you might have to use: 4 + 4 + 4 – 4. Let me know if you have a go!
