Investigation 3 - Solving Equations

In this Investigation the students are looking at working with and solving linear equations.

Essential Questions:
1. How are the coordinates of a point on a line or table related to the equation of a line?
2. What does equality mean?
3. How can the properties of equality be used to solve linear equations?

Here are the notes from Inv 3.2 showing the exploration of equalities.  In the notes we show two methods to solve for an unknown variable (visual and mathematical).

Inv 1.3 and 1.4 Class notes

New Unit - Moving Straight Ahead

The primary goal of this Unit is for students to develop an understanding of linear relationships. Students recognize linear relationships by the constant rate of change between two variables in a contextual situation, a table, a graph, or an equation.
