Area Model and Factoring #2

published by David Wees on Sun, 2018-02-04 10:35
Preview: 

This task helps students build an area model of quadratic expressions for both unfactored and factored forms of a quadratic expression. This version includes negative coefficients in the factoring and uses color to distinguish between positive and negative terms.

One potential modification for this task is to remove the unsimplified in-between step between the factored and unfactored forms and let students determine what those forms should be during the exploration phase.
