Product Description
These change unknown (missing addend) story problems were created to be used for differentiating with in kindergarten, first grade, and second grade classrooms (29 pages in all). I have made 2 or 3 copies of each problem to differentiate with a similar problem. (First problem includes the equation 4+?=13 and the following worksheets 11+?=34)


These could be used as a station in a math workshop, as work for guided groups, as homework, as assessments, or they could be used in a math journal.

There are also Spanish only and bilingual versions available.
