In case you are trying the MARS MAP Classroom Challenges for the first time, it is recommended that you read the Brief Guide for teachers and administrators before you get started.
This lesson is designed to enable students to develop strategies for describing relationships between right triangles and the radii of their inscribed and circumscribed circles.
Before the lesson students attempt the problem individually. You review their work and formulate questions for students to answer in order to improve their solutions.
At the start of the lesson students work alone answering your questions.
Students then work in groups in a collaborative discussion of the same task. In the same small groups, students are given some sample solutions to evaluate and comment on.
In a whole class discussion, students explain and compare the alternative solution strategies they have seen and used.
To help you assess how well students are able to use geometric properties to solve problems.
Tt will help you identify and help students who have difficulty decomposing complex shapes into simpler ones in order to solve a problem.
Tt will help you identify and help students who have difficulty bringing together several geometric concepts to solve a problem.
Tt will help you identify and help students who have difficulty finding the relationship between radii of inscribed and circumscribed circles of right triangles.
