These resources are part of KET's Math Instructional Strategies: Geometry collection.
Teacher Interview: Students' Questions, Part 1 (Video)
While it is important that learners have guidance during their initial practice efforts with a new concept, sharing and evaluating others' solutions can also be instructive to both the teacher and the other learners. Often, an instructor can discover where a learner's thinking process has gone awry and ask the class for their thoughts on why this was an erroneous solution. Learners can observe that there are sometimes several ways to solve a problem that result in the correct answer. This can result in an appreciation of tolerance for others' opinions and judgment.
