This was the first time I have taught conics in my Algebra 2 class. I loved creating a new unit, finding all the good stuff on the internet and putting it together. Now, I will need to do the same for all the trig stuff.
Anyways, I almost had too much for conics, but here are a few fun things we did with conics:
When we did parabolas, the idea of focus and directrix was new, so we used waxed paper to create our own parabolas. A quick and easy, yet powerful activity:
When we learned ellipses - why do they have two foci? This drawing activity helped them grasp it. I love setting up activities like this that will last over the years. I took graph paper and laminated it. I collected the box tops to our copy paper to use as little tables. We put the graph paper on top and put 2 push pins in for the foci. I used wet erase markers. I was going to use string but couldn't find it at Lowe's. I found something else but it didn't work so a colleague recommended floss - perfect. I cut them out and tied them ahead of time. Don't make them too big or it will go off the box top. I had my spray bottles to clean them. Here is my box of supplies and a finished result.
I mentioned conic cards from Cindy Johnson. We sorted a different conic each day. This picture shows the kids doing all 4 conics in groups of four. They were really good at it.
Now, to find lots of goodies for trig, trig graphs, and trig identities....hint, hint....
