Review decimals operations (mental addition and subtraction of decimals, multiplication and division of decimals by 10, 100 and 1000 and multiples thereof), and ordering decimals to the hundredth and thousandth, with no prep printable math center activities. Originally designed for 4th, 5th, and 6th Grade, these 7 Hidden Word / Spot the Mistakes puzzles are an engaging alternative to standard worksheets for your decimals unit, and make great bell ringers / starters, early finishers challenges, and homework tasks too. They can be completed by individual students, pairs, or small groups, and they may not realize they are learning, which is always fun to see! You can purchase this packet in great value BUNDLES, either alongside other review puzzles packets or with a decimals game packet. Please click through on the links for details.
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.
