7.RP.1

7.RP.1. Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units

- Activity to introduce or review methods for extending ratio tables (or alternative proportional relationships)

This lesson about [|Nana's Chocolate milk] from Dan Meyer is actually coded 6.RP.3, but I thought it would be a nice introduction to 7.RP.1. Connects nicely to tasks from illustrative math: [|Cooking with the Whole Cup]

- This powerpoint worked well with students working on their dry erase boards and lots of discussion about whether the ratios had the same unit rate. - This is a method I learned about from Fawn Nyugen. (see her original blog post on it here.) I started my handout with unit rates with whole numbers and then progressed to fractions. I used this graph paper method for dividing fractions and really liked the different ways it made my students think about dividing fractions. - I wanted students to be able to practice the visual method and also learn the standard algorithm for dividing fractions...these problems connected to students being able to see that dividing by a number is the same as multiplying by its reciprocal.

- Exit ticket for dividing fractions and comparing unit rates

Turbo Lesson- Lesson idea from @jreulbach - Use a clip from Turbo to have students figure out the unit rate of Turbo and possibly compare to a real snail. Tie back in at 7.RP.A.2 for tables/graphs and @7.RP.3 for percent increase and ? Added idea from @absvalteaching...start with 1/2 mile in 1/2 hour...how to change to unit rate. > - idea from @nathankraft1: a snail travels at .0022 mph...give students the speed and the distance, but not time. Instead of showing entire video, pause and have students predict time to go the 36 inches.
