Made4Math - Function Operations

It feels like it's been forever since I blogged! One of my New Year Resolutions was to find more balance in my life and while I'm happy to report that it is going well, it has meant a decrease in things like blogs and twitter. I've not had an extremely creative semester, so far, but here's some goodies from this past week :)

Function Operations
Last week, one of our lessons was on function operations... you know, (f+g), (f-g), f(g(x)), etc and honestly I thought it would go very smoothly since we had already done polynomials. Oh my goodness... it was a diaster! I did a self-guided worksheet (you can see it HERE), and thought the kids would zoom through it, but no... it took us TWO DAYS! I was at my wit's end and so frustrated because it was issues that I did not even anticipate!

Anyway, to make a long story short, we needed practice... and LOTS of it! So I grabbed my handy flash cards, a marker, and one of my big dice and here we went...

We picked an f(x) and a g(x), then rolled the dice to tell us what to do. It was definitely good practice! Crisis averted!

Inverses Foldable
So the next day, our lesson was on function inverses. It had been a while since we had done a foldable, so we did a foldable for our notes.

Let's just say that after a stressful week, I enjoyed coloring the foldable! :)

Don't Forget!!!!
The rest of this week's posts are now archived at - Head over there to see the rest of the goodies this week! :)

I thought my students would do well with function operations, too. But, they really struggled and are still struggling with them when they come up as review problems. I think I may use this activity as a refresher in the next few weeks. I love the dice-rolling aspect!

Hi. I have to admit I do like the colors on your photo on functions. This is a surprise to me because I am color-challenged and don't see all the colors most people see. So just a word to the wise - some of us are color-challenged, with particular problems with red and green, and colors that contain some red or green. But your colors were fine with me.
