Supporting Dialogue

When engaging in the tasks in class, invite your students to attend the quantities in a problem by asking them:

1. In this problem, 4 is a number that enumerates a quantity, the time it takes for the blue car to finish a 10-mile journey. Work with your neighbor to make a list of all the different quantities in this problem.

2. Ask students to share a quantity that they noticed. Ask who else has this quantity on their list. Ask if a student has another different quantity to add to the class list. Continue this process until there are no more new student contributions.
