They can be completed individually or in pairs / groups. These puzzles are similar to codebreaker puzzles, with a math-related word to be revealed after completing the calculations. Each puzzle contains a grid. Within each box is a decimals calculation and a letter. Students circle any boxes containing errors. Then they put together the letters from the remaining boxes to reveal a math word. On some puzzles there is a further challenge question / task at the bottom of the page linked to the hidden word.
Students often forget or avoid checking their own work for errors so it’s great to get them carefully checking the calculations in these puzzles. Spotting common errors may help them remember to check their own work and help them avoid common errors themselves.
The range of puzzles in this packet is ideal for differentiation, revision, and / or to cater for a range of groups and classes.
