Students often struggle to transcribe appropriate expressions to represent word problems in general, especially involving integers. This worksheet starts with what students know--the answers. Students often solve incorrect expressions without ever giving thought to the reasonableness of their answers. Therefore, if we start with what students can reason to be the answer to a word problem, students may then realize an addition or subtraction expression that they have written is incorrect because it does not result in the answer that they know to be correct.
Once students have had practice with writing the expressions, the worksheet progresses so that students first write the addition and subtraction expressions and challenges them to assess the reasonableness of their resulting answer.
Finally, students are given an expression and must determine which word problem matches the expression; students are also challenged to write a word problem given an expression.
