Teaching Conic Sections (and a FREEBIE!)

Do you teach conic sections?  It's a fun topic that has lots of real world examples you can talk about.

For example, check out my post on the parabola (Parabola Blog Post)...and the ellipse (Ellipse Blog Post)...

But, there's lots of confusing vocabulary...and algebra too!

Students need lots of practice.

I have created some task cards to help students practice working with each of the types of conic sections.

Here is a picture of the ellipse task cards.

(Check this out here: Ellipse Task Cards)

I also have been working on an activity students can do digitally...awesome - no paper :)  In this activity, students look at a graph of a conic section and match it to its equation.  There are 4 pages which contain equations and graphs for each of the conic sections.

And, for you dear blog reader...a FREEBIE - here is a link to a Conic Sections Word Search - free in my TPT Store:

Need to Decorate your Secondary Classroom? Just for Fun Math Posters

Seriously...Bulletin Boards...the bane of my existence - really you want me to change the bulletin boards AND teach kids the quadratic formula???

I start the year with good intentions, but how is it that the same thing I put there in August is still there???  I guess I just get busy - incorporating technology, grading papers, going to meetings, keeping up with paperwork, and ...oh yeah...TEACHING! that I forget to change the bulletin boards :)

Then I got to thinking, maybe I could create some mini-posters that I could keep in my closet and change them out every once in awhile.  I'll make a note in my super cool teacher organizer each month and remember to change them monthly or so.

So, here are a couple of samples of posters that are in my Just for Fun Math Posters Bundle:

1) Math Teachers Are Pirates


2) I see you have some graph paper
3) Keep Calm ... Do the Math

4)  Albert Einstein Quote.

There are 9 posters in this bundle so far...I'll be adding more as I think of other things to add.  Check them out here:
