This goes over factors with lining up. I have included number lines to help the strugglers for the half way point. As a teacher, I realized some students struggled with things like let's say 2x55=110. The visual helps those see the connections to their factors. It's enough that they know the 2 part, but the rest can be deal breakers. I also added a number line for fourths. This relates to fractions, which gives a snapshot with understanding number lines. Overall, there is tons of practice for factors and multiples! I have included an assessment on the last couple of pages.
