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).

Cool Beans! This puzzle is suitable for Algebra I students (early algebra). There are 10 sets of questions. The answer for each set becomes part of the web address for the next set. Can you get to the end of the Maths Trail?
