This activity provides participants with an opportunity to explore their comfort level and fears around teaching geometry and spatial relations.
Activity for Teacher Educators
This activity begins with participants reading The Mathematics of Geometry and Spatial Relations handout and the "When is a Triangle a Triangle?" Vignette. This can be assigned as homework prior to the session, or during the session before starting the activity. The accompanying worksheet and PowerPoint slide have a set of questions that participants should reflect upon prior to group discussion.
Ask the participants to spend some time thinking about their answers to these questions (if using the worksheet, they can jot down their thoughts) prior to discussing the questions in their group.
Call on groups to share their answers with the class. Participants may share differing levels of knowledge and comfort with geometry and spatial relations. Encourage participants to share both challenges and successes in the classroom and in their own learning.
