To begin, we made another foldable titled "Zero Is A Hero: Division". One half of the paper focused on estimating quotients to division problems with one digit divisors. I made a video of this session and it is available on youtube at: Zero Is A Hero: Division (part 1).
The second portion of the foldable focused on estimating quotients with division problems with multiple digit divisors. This second video is also available on youtube at: Zero is a Hero: Division (part 2)
Compatible numbers are extremely helpful when we work with division using multiple digit divisors. It will help determine a reasonable starting place.
