This is a fun matching activity for students to practice finding determinants of 3x3matrices.

Students evaluate the determinants of 12 matrices labeled (going) each with a mask. Then they look for their answers on a given picture with students鈥� faces and their names and find out who is hiding behind each mask.

(It could be presented as a story about students who had a masked ball in which the participants attended wearing animal masks. Students decided to reveal each other who had been hiding behind each mask during a special lesson in math on determinants of matrices).

The activity can be used individually, in pairs or in groups of 3 or 4.

Student recording sheet and answer keys are included.
