In this Lesson plan students use matrices to construct visual representations of possible combinations. The lesson plan follows the Cyberchase kids through 3 short video clips in which they use logic grids to display data combinations to solve problems. Then what is learned from each clue can be identified in the matrix and other possibilities can be eliminated. The lesson plan includes 3 short video clips, 3 documents for student work, 2 assessment options, and an answer key.
