Friday Freebies! Comparing Linear/Quadratic/Exponential Functions

My students are testing today on the unit we introduced with Zombie Day


We used a "Fun with Functions" Cut and sort activity to practice identifying/classifying LQE functions.
 We spent plenty of time working with multiple representations of each, and how to write the equation for a function once you know what type it is.

Then we moved on to translating, with matchbook notes. 

And after seeing this blog post from Math=Love, we included a drawing of our calculator yesterday when talking about using the regression functions on our Ti-84s. 

And we practiced, and practiced, and practiced. 
We did a scavenger hunt.

We used LQE cards on the 2nd day of the unit for whole-class response practice. 

The following day, we increased the level of difficulty by using cards that said what type of L,Q, or E each example was. (The exponential card had decay on one side, growth on the other)

I wanted to do so much more with this unit, but there's only so many days left until testing season begins.
However, I do think that having a day of centers would have been better than only doing the practice in mostly whole-class settings. So I made a card sort for this unit (using this 12-block template) - we'll use it for EOC review. I wrote up the process for using a similar 9-block template in this previous post.

Here are some of the ways I'm thinking of using the LQE cards (it's a set of 48)
  • printed 2 to a page, into a column sort in their ISN
  • printed onto cardstock, used as Go-Fish or Memory (each exponential matches with any other exponential)
  • printed onto cardstock, used as a center matching activity (3-column sort as a group onto a posterboard or table marked with 3 sections)
  • center activity where students play Left-Center-Right, but to keep/receive a card, they say L/Q/E
Start the download for the card set by clicking here. It's a Word docx file, so feel free to edit it to suit your students' needs. 

Have a great weekend!

  1. These notebook pages are GORGEOUS! And, they make me super sad that we're done with notebooking and new curriculum for the school year... I guess I could start planning for next year...
