For the last few years, we've been using this quadratic keyword poster during our quadratic word problems unit and it has been so helpful.

The reference highlights the vocabulary students see in word problems that ask for time to maximum height, the maximum height or the total time in the air.

I made a flipbook version of the quadratic poster that I thought would be fun for student notebooks.

Before introducing word problems, I teach my students how to find maximums and zeros of parabolas on the graphing calculator. This projectile motion poster helps so much with tricky "left bound" and "right bound" and hangs as a permanent part of our math word wall.

( I made above posters by following the directions in this poster making post. )

Before ever introducing equations during our word problems unit, we do this quick numberless quadratics activity.

This quick sort gets students looking for the keywords that will signal whether they are being asked to find the positive zero or a value at the maximum. Then it's time to introduce the equations.

We also use this rocket launch template for warm ups during this unit. I shine a word problem on the board and each student grabs a template from the warm-up basket.

Students then find maximum height, a good graphing calculator window (my students need a lot of practice on this), time to reach maximum height, maximum height and total time in the air. They then sketch their graph. We talk about how everyone's graphs could look different - and how they are all just as right - based on the window.

Here is an example of the template all filled out. I give 1 point for each correct answer if I feel it's a good day to award some credit (ie: kids are starting to slack off!).

This might be a big controversial, but I do not like tests. In just a few short weeks, my students go from never having touched a graphing calculator to finding how long an object is in the air, and this is TOTALLY AWESOME.

I don't want a bad grade on a test to take away from the confidence my students have built. So instead I quiz with this set of quadratic word problems task cards.

Students are allowed to work together and ask me questions. They can also use their reference sheets and our math word wall references. One of my students this year asked if he could take his task cards home to work on! This made me feel good!

It's amazing what a little color will do. When I first made this Quadratic Formula anchor chart, a, b and c were black like the rest of the formula and my students were not using it as a reference. After adding the white (white-out), the poster became a much more useful tool.

I enlarged this quadratic keywords poster with the instructions in this post. I also added this blank version to the file so that it can be used as an anchor chart or place to take notes.

I love teaching quadratics. I wrote more about the activities we do in our quadratics unit in the blog post Fun with Quadratics.

Interesante trabajo. Felicitaciones.
