The second instructional activity on finding inverse matrices asks class members to look for a pattern in the inverse matrix and test it to see if it works for all matrices. The teacher leads a discussion to refine the process in finding inverses, then individuals use the refined process to determine when a matrix does not have an inverse.

Instructional Ideas
- Conduct a discussion about what types of functions did not have an inverse and make the connection to matrices that do not have inverses
Classroom Considerations
- The class should know how to determine the inverse of a matrix with determinant of one
- Pupils need to know how to fluently calculate the determinant of a 2 X 2 matrix
- 30th segment in a series of 32
Pros
- The teacher resource contains expected responses to teacher questions
- The scaffolding includes suggestions on possible grouping strategies
Cons
- None
