I made this organizer to help students multiply by partitioning the larger number, then multiplying by the single digit, and adding the parts back together. It is simpler than other ways that I have seen. I will be using this in my class next week. I will have my students put the finished organizer in their math notebooks as notes to study by.
It would be a good idea to use the base ten blocks as a hands-on activity before having them complete this organizer. I always do several with my students to make sure they understand how to use the organizer correctly.
