Here is a foldable I created for my students on operations with functions. It's my favorite lazy type of foldable. I say foldable, but it's really just a sheet of paper folded in half with practice problems inside. We like to call these "books" in my classroom. Of course, this gets confusing because we call poof books the same thing...

Inside:

I wanted a way to make practicing this a little more fun because I have to be honest: this isn't the most exhilarating Algebra 2 topic to teach.

I spotted some foam dice in my room and ended up coming up with this:

I wrote up a list of functions that I thought would operate well with one another.

I think I had to end up adding a few more random ones to have enough for all of the students in my class. These ended up being written on colored index cards.

Each pair had to decide which function to make f(x) and which function to make g(x). Then, they rolled the foam die to determine which function operation they would have to complete. Let's just say they got very, very aggravated when they rolled a six!

The blank box to the right of f(x) and g(x) was meant to write the operation they were completing. The large box was meant to show their work. And the small, skinny box was meant to record the final answer.

As students finished a problem, they raised their hands and had them checked/stamped. Once their work was checked, the students traded index cards and found a new partner. For the record, high school students get super excited about stamps!

If I were to do this again, I would give them more problems to do because some students ended up avoiding multiplication or division.

I would also have them roll a die and evaluate the final function at that value.

Files for this lesson can be found here.

What a great way to make learning functions more fun! Thanks for the fun idea!

You're welcome!

DeleteI like this set-up for the way it gets students working with a variety of partners, moving around the room, and practicing without it feeling too much like a worksheet. Thanks!

ReplyDeleteMy kids definitely complain less about practicing when it doesn't look like a worksheet!

DeleteWhat a fantastic activity! You are so creative. Thank you so much for sharing. I really appreciate the inspiration.

ReplyDeleteThanks for the sweet comment, Jennifer!

DeleteOne question I have after looking at your foldable. Don't you have your students put restrictions on the denominators so they don't become undefined?

ReplyDeleteOklahoma doesn't test on domain restrictions, so I haven't taught it in the past. I probably should, though.
