Use the 16 activities in this interactive Microsoft Excel file to help students master the slope/y-intercept form of linear equations.
Part 1: Explore and Connect
Use Excel to randomly generate examples of linear equations. Teachers can elect to generate examples with or without fractions.
For each graph, Excel will display:
1. The equation in slope/y-intercept form.
2. The graph of the equation.
3. The table of values from -5 through 5.
All three components are displayed ON ONE PAGE allowing teachers to easily demonstrate the relationship between each component without toggling between screens.
There are 5 different linear equation pages for students to explore and master:
1. Positive slopes with whole numbers.
2. Positive slopes including whole numbers and fractions.
3. Negative slopes with whole numbers.
4. Negative slopes including whole numbers and fractions.
5. Zero slopes.
Students can also master their graphing calculator’s functions by:
1. Entering the same equation shown.
2. Viewing the graph.
3. Going to the table view.
Part 2: Matching Practice
“Matching Practice” presents students with the challenge of entering the slope and y-intercept for one equation (shown as a blue line on a graph) until it matches a second equation (shown as a red line on the same graph). There are 10 “Matching Practice” graphs. Perfect for warm ups, classroom discussion, or independent review.
