OGAP Evidence Collection Sheets can be a useful tool for recording the results of student work on OGAP items that can be sorted by strategy. These forms were given out in training and can be found on our website under Record Keeping Forms (the password is evidence) for Additive (K-2), Multiplicative (3-5) and Proportional (6-8) Reasoning. Notice that the columns on the form parallel the levels on the corresponding OGAP Progression. These forms can be used to keep track of evidence related to 1) the level on the progression of student strategies; 2) errors or underlying issues; and 3) accuracy of solutions.

 

In the sample shown below, the teacher has recorded a student work sort on the Multiplicative Reasoning Evidence Collection Sheet.  Student names are listed under the strategy level evidenced, substrategies are noted, and student names are listed under specific issues and errors when evidenced. In addition, incorrect solutions are highlighted.
