A new multiplication/division model is appearing on standarized assessments. It is a simple model - the same as the group model, for the most part. However, students still require a small amount of exposure prior to the annual assessment.
This is a page and a half pegagogy paper that rapidly accelerates a teacher - especially entry level and new teachers to a intermediate, elementary testing grade.
I know how much teachers and principals hate to read anything with such stressful days at school at this time of the year, so I made it as absolutely brief as I could.
Best to you and your students. Blaine Helwig
