A flipchart that I have used to introduce polynomials. It includes a couple of cool pages - a page on the 'cubic' equation (like the quadratic equation, but a bit more complex) and a page on the 'quartic' equation (which is a tad more complex than the cubic equation).

Here are two versions of Completing the Square - a web page from NCTM and an ActivStudio flipchart.

This is an ActivStudio flipchart on introducing logarithms. It includes a fully working interactive slide rule! How cool is that.

Here are a variety of probability experiments, from throwing coins, throwing dice, choosing playing cards and spinning spinners.

A flipchart on the vertex form of a quadratic function and its graph.

Doo-dahs are a wonderful way to bring information into a classroom discussion in a controlled manner. A Doo-Dah can contain text, annotations or images, even those added or created on the fly. A picture is worth a thousand words, so download the file and have a play. You will soon learn the power of doodahs!

If you have group competitions in your class, this is a neat way to keep a running score (up to a maximum of 30 points per team).

A wonderful collection of clocks. The time comes from your computer's system clock, so if that is correct, these clocks are as well.

Five 10-second timers, each of which culminates in a bomb. And you can even have more timers if you wish by first choosing 'Disable Actions' in the upper right corner and copying and pasting one of the bombs.

This ActivBoard flipchart keeps the scores for up to six competing teams.
