Investigate and use rate in real-world situations.
The core standards covered in this lesson
6.RP.A.3 — Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
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?

Chichén Itzá was a Mayan city in what is now Mexico. The picture below shows El Castillo, also known as the pyramid of Kukulcán, which is a pyramid located in the ruins of Chichén Itzá.
The temple at the top of the pyramid is approximately 24 meters above the ground, and there are 91 steps leading up to the temple.
How high above the ground would you be if you were standing on the 50th step? The 33rd step? The 80th step?

On your way home from school, you stop at the corner store and pick up some eggs and apple juice. However, you don’t need as many eggs or juice cans as come in the package. The cashier lets you buy only part of the package and pay only for what you buy. About how much is your total bill? (Note, the prices shown are for a 6-pack of juice and a dozen eggs, respectively.)
