This is a Mathematical Thinking I am very happy with. It is designed to be used in the first 10 minutes of class to engage students in the topic.
For EnVision Math this is meant to go with Grade 5 topic 5 lesson 6. However, this would work with any lesson that involves division.
This "thinker" uses images from an app, Car Town Streets, and compares how many coins each car earns the player. The interesting part is each car gives different amounts of coins on a different amount of time. Some are a minute, 2 minutes, 4 minutes, an hour, 4 hours, a day. Students use of conversions will be very important.
