Day 63 – Least Common Multiple

Math 8 – Today was a pretty quiet day. The kids did some practice questions, and we spent some time going through what is a Least Common Multiple. First I had to find out if the students actually knew what an LCM is, which was a harder job than what you’d imagine.

We finished with voting on finding which ratio is bigger. This led to a good discussion on comparing ratios, equivalent ratios, and problem solving. Which is bigger, 17/32 or 17/33? This can be confusing, but students know that 17/2 is bigger than 17/33. Therefore 17/32 has to be bigger than 17/33.
