Decimal Subtraction Puzzle
Students must rearrange 9 puzzle pieces so that the subtraction problems match the solution on each side. Once finished, the puzzle will be a 3 x 3 grid which is easily checked by teacher using the "mystery word" that it spells (left to right, top to bottom).
This puzzle is intended for fifth grade use, but may be good practice for 4th or 6th. Subtraction problems include tenths, hundredths, and thousandths and do not always match up with the same (i.e. not only tenth + tenth, but tenth + hundredth) so students must know how to line up decimals. Also, some problems contain more places in the second number so that zeros must be inserted in the first number.
I have used a puzzle like this in my remediation class of 6 fifth grade boys who eagerly solved decimal addition problems in order to "beat" the other teams. This helps with fact fluency and is good practice.
