Notebook:
A unit rate is a rate that has 1 as a denominator (bottom number).
Whose heart beats faster?
Let's create two ratio tables and compare the unit rates.
Let's create two ratio tables and compare the unit rates.
Since 60 seconds equals 1 minute, we can say that Julia's heartbeat is 72 beats per 1 minute
and Bobby's heartbeat is 75 beats per 1 minute (bpm).
We can multiply the rate by a Useful One:
Make a ratio table.
Find the unit rate (in feet per second) of both 6th graders.

Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger."1
CCSS.Math.Content.6.RP.A.3.b
Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?
