5th Grade Order of Operations Error Detective worksheets

About this worksheet

The order of operations says to work inside parentheses first, then multiply and divide, then add and subtract. A common mistake is to work from left to right and do the addition before the multiplication. On this fifth grade sheet each of ten problems shows an expression and the answer a student got by mistake, and the child works the expression in the correct order and writes the right answer on the line.

Each version has different problems, and the answer key gives every correct answer.
