This is an enrichment that ties directly with another product of mine, "Which is the better buy." Both are both off images from a free app, Car Town Streets.
This enrichment can be used in Topic 5 of grade 5 EnVision Math or Topic 7 of Grade 4. However, it could also be used in any other lesson involving division.
In this enrichment, students need to determine what is the best option for making parts for a car. The catch is the result is not what most people think it is.
