8.EE.5 – Graphing and Unit Rates - Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
What we are covering in this unit is rates, unit rates and the graphing of unit rates. As the Common Core Standard state in 8.EE.5, which is our standard for this unit. Here's what we are trying to do in this unit:
Before we get started on the unit, let's see how much you already know. Take this pre-test to the left and see how much you already know about rates, unit rates and slope.
How to find the unit rate from a graph.
These is a VERY good Site to practice several parts of this unit
A great place to start and see what we are doing is to head to the KHAN ACADEMY video and see:
Here's another good, quick video to see how to make unit rates from a regular rate. Notice the denominator has a unit of 1.
We would have a chance to see more about slope and unit rates here. This interactive site allows you to see quite a bit about how rates and slopes work together.
