Here are six resources that talk about the quadratic formula. 1. Polynomial Puzzler This lesson talks about reinforcing multiplying monomials and binomials and how to factor trinomials. How this lesson goes is that there are 9 blocks that are 3x3 and the way that it is done is the students can make a polynomial across and then down.

2. Math Warehouse This link is very similar to the one about except when you plug in numbers for the a, the b, and the c it actually shows how it would look in an equation. Also it shows the work that is needed to solve the problem that you plugged in. At the very bottom of the work it has what the actual value if x should be.

3. PurpleMath This link explains the quadratic formula in detail. It has three pages to it, the first two pages have examples of the quadratic formula and how it is used also they have graphs that would help the student review or make connections that the quadratic formula and graphing does go hand and hand. The examples would be a great way for the students to look at to understand the concept better. On the third page it has a chart that shows what would happen if there is a perfect square under the radical, if there is a zero and if there is negative number that ends up under the radical.

4. Math is fun In this link there is another quadratic formula calculator but right beside it there is a graph. If you where to use this in your classroom then the students would be able to see the graph as the calculator solve the equation. There is also a chart that is on this page that shows the quadratic formula in "disguised", since some students get the test and if the question is said differently then they think that it was not talked about in class. I think that the chart would be a good thing to show the students so they are not as confused in a question is worded differently that it was in class.

5. Algerbra.help This link is wonderful if you want to have a review day and just want your students to do quadratic equations for a while. The students can work on these problems and once they are done they put the answers that they came up with and then click on the check worksheet option that is at the bottom of the page. There are twenty problems so that could last them awhile doing all of the work out.

6. Algebra-Class Here this link tell about the quadraic formula and what it can and cannot be used to solve a quadratic equation. I just like that there is a chart that would be helpful for students, it would be like a little study helper for them.
