Cluster: Understand ratio concepts and use ratio reasoning to solve problems

Standard: Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”

## CCSS.Math.Content.6.RP.A.3: Limited (1)

We noticed there were some typos in the lesson. For example, the number of the items are out of order. Also are the ratios in the table for item 5 intentionally incorrect? We felt this was not clear. Is there a line of reasoning which is missing?

Multiplicative reasoning is stated, but not really dealt with in a way where students work on developing their understanding of it, unless the teacher knows to do it on his/her own, through questioning. Perhaps more teacher notes are needed?

The activity is good, but there seems to be errors in #5, which affected my rating.

Although there is an explanation, there isn't enough depth.
