This is a great worksheet (even if I do say so myself)
. It is based on a word search grid. The only difference is, to find which words are in the grid, students must do a math operation.
Worksheets have to be purposeful. Not only that, they have to be economical on your time. CLICK HERE if you want to download this file.
Let me know if you like this one and I will knock up a couple more.
