CGI- Strategy Practice for Addition

Created by

After teaching 2nd grade for several years, I observed that my students were confusing the following strategies: direct modeling, counting on, counting back, and using invented algorithms. Therefore, I created this resource to model the different strategies for students.

This product can be used for direct instruction, practice, and/or assessment.
