This week we actually have only three days of math instruction. We will be taking the MAP Mathematics test on Wednesday and Thursday.
So for the short week, we will begin our new unit by reintroducing unit rates (from 6th grade) and move on to complex unit rates. Before this unit, students worked with ratios of whole numbers and with whole number percentages. Now they start to work with ratios of fractions and fractional percentages. This week they encounter situations where a ratio of fractions arises naturally. They consider a situation involving a ratio where the second number is 100, in order to prepare for thinking about a percentage as a particular type of rate, and they compare rates associated with different ratios. The representations they use are the same as they have used previously, but in the context of more complicated ratios. Comments are closed.
