This lesson involves substituting values for variables, and evaluating expressions. The emphasis is on helping students understand that an expression and an equation are two distinctly different mathematical objects. Students will slide a point attached to an arrow along a number line and be asked to observe the changes that take place in the expression as the value of the variable changes. As a result students will make conjectures about the connection between the values being substituted in the expression and the outcomes. The lesson could lead to solving a linear equation in one variable or be extended to generating a table of solutions for a linear equation in two variables. Products: TI-Nspire(TM) CAS, TI-Nspire(TM)
