Preparation
Lesson Narrative
In this lesson, students continue to solve problems but encounter those that cannot be solved right away because of missing information. They learn the Information Gap routine, which prompts them to consider the information that is needed to solve a problem and ways to ask for it.
The first activity introduces students to the routine. In the second activity, students are given more time to solve two-step word problems as they engage in the routine.
- Representation
None
- Determine the information needed to solve one- and two-step word problems. Ask (orally and in writing) questions to elicit that information.
- Representemos y resolvamos más problemas.
Required Preparation
- Create a set of 4 cards from the blackline master for each group of 2 students.
- Keep the two problem/data pairs separate.

How did the Information Gap routine support students in making sense of two-step problems?
