Exponential Equation Matching

on February 9, 2013

One of my goals for my 9th graders is that when I give them an equation, a context (story), a table, or a graph for an exponential equation, they can create the other three things I didn’t give them.

They could do the equation, table, and graph parts pretty well, but struggled with coming up with a context to match it.

We kept doing examples in class, but they just weren’t getting it yet.  When we did examples I had them come up with a context then check to see if it matched the table when they plugged in the x values.

A few of them told me they wanted to just see a whole bunch of examples to compare.  So my solution was a matching game with 4 parts to match up.  I forgot to take a picture of the cards!  Maybe I’ll remember to add those later…

Here are the links to the cards:

Context (Stories)

I have several sets of cards printed on different colored cardstock and had the students work in groups of 2-3 to match the sets.  It helped things start to make more sense and most of them can create a context now

  1. […] can find my links to the matching game for exponential equations here.  These ones I like better than the linear!  I started with context first, then made the table, […]

  2. […] math lab class. Things like scrabble with math, tarsia sets, math dominoes, math go fish or memory, card matches, etc.  That might happen over spring […]

    Hi Misty,
    Thanks for sharing your positive approach to help kids learn math. I’m a high school teacher at a vocational technical school in Massachusetts and I love math and my students. I love your exponential function matching game! However the links to equations and context both bring me to the equations. I’m wondering if you could post the contexts as well. Thank you very much for the idea and the cards either way.

    Any luck on getting the correct link for the stories? It looks like I’m having the same issue as Tricia…

    Thank you so much for this lesson. The context link and the equation link are the same. If would enjoy the context (stories), if available

    Hi Thank you for this terrific resource! I was looking for the link to the context but am only seeing the equation document linked twice. Am I missing it?

    Hi Misty, I know its quite a bit of time since you posted this. But I LOVE this activity!! I have done this in the past with Linear models and was hoping I could find someone generous like you to share their game for exponential models.

    I am not sure if you still check this site or even have this activity handy, but the link for context and stories leads to the same equations file you have linked/saved. This is part that required the most creativity and I was hoping there were different scenarios out there where exponential models are used. I was hoping i could share the different situations/context with my students to make them better see the real-life connections. If you do, would you mind posting the link or send it to me. I greatly appreciate it.


  8. I found the same thing as Trish. Both links go to equations. I would like to see the stories, or I suppose I could make them up. Thanks.

    The link for the story problems actually goes to the same document as the equations. Do you have the .pdf link for those? I’d love to use this with my students.
