With the last few days before Christmas break being here, as well as the end of the semester, it gets difficult to keep students focused and engaged. Using a group matching activity keeps students a bit more attentive.

These types of activities were definitely reinforcing communication among students, as well as helping to see who understood how to change equations from one form to another. Those who still weren’t sure about the different forms were struggling. It also allowed students to move around and have some fun with their friends, all while working on a skill that is often difficult for many students.

This activity is a new one this year. I have had had students match linear equations and graphs before, but not different forms of equations and the graphs. This one uses standard form, slope intercept form and graphs. In addition, students had to make note of the slope and the x and y intercepts.

By working in small groups, students were able to discuss possible matches. Waling around the room, I was able to observe different strategies. Some groups started with the graph and tried to make matches from there. Others started with one form of the equation and tried to make matches. Some filled in all of one form of the equation before starting. Others chose to work with one equation and get all the blanks filled in before moving on. I purposely let students decide the strategy that worked best for them.

Usually, I have students work in their set groups, but, I decided to let them choose groups. My one word of caution, when they choose groups, is “Choose wisely.” Just because you have the opportunity to work with your best friend does not always mean that is a good person to work with! Most students actually followed this advice, although a few still worked with their friends, with varying degrees of success.

It was interesting to note how all students came up with some systematic approach t to completing this task. They are beginning to make connections among the different forms of linear equations. When I do this in the future, I may add another set of cards that have the equation in point slope form, which only one of my students likes. This could add another level of discussion to the class, and make for some interesting discoveries.

Here is the link to the actual document used. I can’t take credit for this, as I found this somewhere, and then modified it to fit the needs of my students.
