A Hidden Words puzzle aimed at 11- to 14- year olds, containing mathematical words that they should know
There are 32 hidden words hidden in this grid. They are all mathematical words that you should know for Key Stage 3 (UK). They appear horizontally - left or right, vertically - up or down, and diagonally - forwards or backwards. All words have four or more letters.
At the beginning you do not know which words to look
for! But if you want to make it easier, click the box next to "Words
