In this activity students will practice graphing equations by using a table
Students will work in groups and graph different types of equations with a table. These equations include exponents, radicals, absolute value, rational expressions, and a mixture of each. Students will learn that they can graph any equation by using a table. Each equation they graph will lead them to another until they have completed them all.
This activity can be used as a race between the groups or you can allot certain time to finish each graph.
Divide students into groups of two or three, assign them a group number, and give each student a recording sheet where they will work out their problems and record their answers. Every student should create their own table with different points, but you can allow each group to just do a single graph. Display the beginning problems so that each group knows where to start.
When a group thinks they have correctly graphed an equation, they bring it to the teacher’s table to check and match it with one of the graphs located there. If they are correct, the back of the graph cards will give them the next problem they should work on. If they are incorrect, I have them return to their desk and check their work. I have students spend at least three minutes in the checking phase so that they do not just come up immediately after and offer another “guess.” This is also essential if you are letting the groups race against each other.
Each group will be finished as they complete their tenth problem which should carry them back to the problem they started on. You might want to begin by telling everyone some rules concerning running or fair play. It’s fun to have groups a treat as they finish the hunt. I like to allow the teams to pick their treats in the order in which they complete the activity.
