The past two weeks in my class has involved solving quadratic equations. We finally derived the Quadratic Formula which can be used to solve any quadratic equation. I was also able to find a Quadratic Formula Calculator on the internet. This is a great tool for students to use at home to ensure that they are using the formula correctly. Below is the link to the calculator:

My first experience seeing an interactive whiteboard in use was in my son's 10th grade math class. The teacher had a computer version of a graphing calculator that she pulled up on the whiteboard and demonstrated to the students so they'd know what to do on their own calculators. I was amazed at how much technology existed for teaching math! Now it looks like there's even more, and I'm sure it makes teaching math a little more fun.
