The video at the top of the page will show some examples similar to the ones I showed in class. It is important to remember you cannot cancel anything that is being added or subtracted, the factor or term must be multiplied in order for it to be cancelled. Most of the work in these types of problems will be finding common factors and factoring quadratic expressions. There are yet more examples here. Finally, if you want to quiz yourself, try some here and see if you can do them correctly.

• factoring out a monomial (find the greatest common factor)

• factoring the sum or difference of a cube

• factoring by grouping, shown below:

We will work through some example problems together on the board, students will try some on their own on a worksheet, then they will begin the assignment for Monday.

1/23/2008 Pre Algebra - Solving Equations Involving Fractions

2008-01-23T14:42:00.001-06:00

Today we put our work with fractions to use in solving equations. In order to solve an equation with a fraction coefficient (ie 2/3x = 8), you must multiply both sides of the equation by the reciprocal of the fraction (3/2 for our example). We did some example problems on the board together, students did some on their own on a worksheet, then did a problem as an in class assessment.

1/22/2008 Algebra 2 - Adding, Subtracting & Multiplying Polynomials

2008-01-22T09:05:00.000-06:00

Today we continue or work with polynomials, again laying the foundation for our work later on when will will be solving polynomial equations. We will adding, subtracting and multiplying polynomials today. Adding and subtracting polynomials consists of adding like terms (a review concept). Multiplying can be thought of as the distributive property repeated a few times. Students will take notes of some examples illustrating the above ideas. To see some video illustrations visit these youtube links:

Students will be working on the assignment for Thursday upon completion of the notes and demonstrations.

1/18/2008 Applied Geometry - Applications of Similar Triangles

2008-01-18T07:27:00.000-06:00

Today in class, we continued with the study of similar triangles. Today focused on some different applications of similar triangles.

1) If a line parallel to a side of a triangle intersects the other 2 sides of the triangle, then it divides those sides proportionally.
2) An angle bisector divides the opposite side of a triangle into 2 segments whose lengths are proportional to the other 2 sides.
3) If three or more parallel lines intersect two transversals, then they divide the transversals proportionally

Students took notes from the board, came up with some questions from the lesson, then they worked the graded assignment.
