Big Ideas: Scalars increase or decrease the value of coefficients without affecting the meaning of the equation. Students will look at how a scalar effects an equation in a form they may have seen before. Then they will look at a system of equations and predict whether a scalar helps compare the two equations more easily. Vocabulary: scalar (scale factor), coefficient Special Materials: none
