This was quite a challenge. Keep trying and see if you can figure out how the pieces fit together. Today, a Year 2 pupil at Coton C. of E. Primary School completed the problem in a very short time.

We have a clue here from one reader, "" First of all we started at the top and worked our way down the sides, but near the bottom we needed an eight and we didn't have one, so we started again.

We kept on trying again and again we finally finished and got all of the sides right."

The clue is to keep trying and if your not successful, take a break and try again.

Looking at it through eyes that have had a rest really helps!
