9/19/2007 Pre Algebra-Simplifying Variable Expressions

Today students will continue simplifying and using the distributive property. We will be working with variable expressions again, and will be identifying the terms, coefficients, like terms, and constants in these expressions. Students will practice on a worksheet in class and then work on the assignment for the remaining time. Some futher explanantion from the book's website can be found here.

9/19/2007 Applied Geometry-Slope

Students reviewed slope today. They took notes giving different representations of slope, from the formula to graphs. The first part of the video above shows how to use the formula. The assignment will have students estimating slope, finding the slope, comparing steepness and deciding if slopes are parallel or perpendicular. We completed a worksheet in class for practice and then worked on the assignment.
