Objectives

Students will be able to build their basic high school mathematics skills to help them graph and solve algebraic equations.

Subjects
Math

#### 1 Hook

Activity: Drawing

Plot points, create lines, find the slope of a line.

Then, students will manipulate the slope of the line to see how changing the points changes the slope of the line greatly.

#### 2 Direct Instruction

Activity: Drawing

Graph a line with intercepts, points, or naming a function.

It will also show a table and you can change the scales of the graphs.

#### 3 Guided Practice

Activity: Investigating

Students will be given 4 different graphs.  They have to figure out the story behind what the function represents.

#### 4 Independent Practice

Activity: Drawing — Draw a line with 2 points

Manipulate linear functions and slide the slope and intercepts to see how it changes a line.

#### 5 Wrap-up

Activity: Investigating — Give a line and guess an equation.

The app will give students a line.  They have to guess correct points and the equation of a line in a game format.
