Introduction
(3 minutes)- Pose a real-world problem with information gaps and have students Think-Pair-Share about what other information they need in order to solve it. (e.g., I have a birthday party to plan, and I want to make sure each kid gets two treats. The party starts at 4 p.m. How many treats do I need to make?)
- Instruct students to think about their plan for how to solve it or what additional information they need to solve the problem. Then, have them turn and talk to a partner about their thoughts. Invite the group to share out.
- Inform learners that you provided a problem, but you did not share all of the information. If you shared how many kids were coming to the party, you'd be able to find the answer.
