# Linear and Quadratic Functions – Algebra Review Worksheets

If your kids need some review on linear and quadratic equations these Algebra Review Worksheets might come in handy! They are currently FREE to download! I made these for my daughter so that we can review things like slope (m), the y-intercept, whether quadratic equations face up or down and more!

Just use the link to below to grab these FREE Linear and Quadratic Functions Worksheets!

I have added these pages to the High School Math Posters Packet I shared a while back.  You will find the Algebra Review Worksheets starting on page 15.

### High School Math Posters AND Linear and Quadratic Functions Review Worksheets

You will find both in the same packet!

If you are just starting to go over this with your kids, here are a few highlights about Quadratic Equations & Quadratic Functions to remember:

• Quadratic Functions are those that have an exponent –  x2
• Example: f(x) = x2 + 5x + 6
• f(x) might be called y.
• A quadratic function has the shape of a parabola.
• A parabola can be a happy face or a frowny face. You can tell that by looking at the constant “a.”  If a is positive the parabola is upward (like the picture to the right). If a is negative the parabola faces downward.
• When you solve for x you can do that by factoring the equation or by using the quadratic formula.
• Most textbooks I’ve seen spend a lot of time teaching kids to factor quadratic equations.  Be sure to tell them why they are doing that along the way!! (Remind them (over and over!) that those numbers show you where the x-intercepts of your parabola can be found… i.e. the dots in red above.)
• The vertex of a parabola is the green dot in the picture above.
• Point out to them that a parabola might be located above the x-axis (so might not intercept it).

Anyway, those are some highlights I wish I had known when my kids first started diving into Algebra 2. 🙂

What Math Curriculum are we using for high school? We started using Thinkwell‘s math courses beginning with Geometry.  We LOVE Professor Burger! The video lessons are 5-8 minutes long and the professor will explain a new concept and do a example problem or two.  Then, they can go to the book and do practice problems that he has just described on the video.  My daughter is doing Algebra 2 and my son is doing PreCalc. If you are interested, my Thinkwell referral link will give you 15% off. Note: you can do a two week free trial with any of the Thinkwell courses to see if it would be a good match for you. And of course, if you have any questions you can also send me an email!

### Chemistry Unit

Ions and Isotopes Packet

My daughter did this ions and isotopes unit last year and now completely understands ions (which gain or lose electrons) and isotopes (which have different numbers of neutrons in the nucleus).  This unit is more than 100 pages and is helpful to do in middle school or when your kids get to high school chemistry!

### Biology Unit:

Last year, my daughter’s favorite science unit was on Pathogens.  You can check out that packet here: Pathogens: Bacteria, Viruses, Protozoa, Fungi, Parasites and more!

We also have various history units available such as our World War I Packet
