Mathematics Site for Secondary Students

Inmath is a site where you can view tutorials on almost any secondary math topic. Check it out and let me know what you think. I haven't used it in my classroom yet, but it came highly recommended from an Education World newsletter.

Factoring Help

If you are needing help with factoring, visit the sites below.

Simple factoring by GCF

Factoring Quadratics (simple)

Factoring Quadratics (when leading coefficient is not 1 as in the simple)

Factoring Weird Cases (when the exponent on the variable is not 2)

Factoring by grouping (or in pairs)

Special Factoring (difference of squares)

This should help you with any issues that you are still having questions about on factoring. Be sure to work some examples to be sure that you have the concept.

Graphing Piecewise Functions

Here are two websites that I have found that do a wonderful job of explaining how to graph piecewise functions.

The first shows boundaries and explains really well why the graph can't extend past the "fence."

The second uses Flash to show how part of each graph is removed.

Check them out if you are still confused!

Interactive Slope Activities for Mrs. Osterberg's Classes

1. Use rise over run to pass this quiz. http://www.algebrahelp.com/worksheets/check/graphing/slope.quiz

2. Find the slope of the line that goes through the following sets of points. Then check your answers here.

(0, 0) (1, 4)

(-3, 1) (5, 5)

(-1, 5) (6, 5)

(-1, 5) (7, 1)

(-3, 3) (1, -1)

(-4, 1) (2, -1)

(0, 1) (5, 2)

(0, 2) (5, 2)

3. Practice x and y intercepts as well as see examples worked here.
