Guided Notes
Key concepts students will learn:
- •
A double number line shows how two quantities change together, such as the relationship between pounds of avocados and their cost.
- •
If 5 pounds of avocados cost $9, the cost for one pound can be found by dividing $9 by 5, which equals $1.80.
- •
When using double number lines, the ratio of weeks to trains was 1:9, meaning for every week, Irene can build 9 trains.
