In this video segment from Cyberchase, Delete creates three clones of himself every time he sneezes. The CyberSquad tries to keep track of how many clones there are as they attempt to round them all up.
In the lesson, Multiplication as Replication, students build tables and use patterns as an introduction to multiplication. They are encouraged to use multiplication by 10 or 100 for larger values as the beginnings of commutativity and distribution are introduced.
Frame: Let’s say there is a certain flower that always has five petals. How many petals would there be in total if there were six of these flowers? How about if there were 26 flowers? How do you know? How can you keep track without counting each petal?
Focus: In this segment, Delete's sneezes create clones of himself. Watch to see how Inez tries to keep track of how many clones there are even though she can’t see them all. How does she do it?
Follow Up: Inez says that multiplication is just repeated addition. What does she mean? If Delete sneezed 100 times, how many clones would he create? If every time Delete sneezed, he created 6 clones, how many clones would there be if he sneezed 18 times?
