2/28/2008 Algebra 2 - Solving Radical Equations Review

We reviewed solving radical equations in class today.  Students completed a worksheet during class and then we took a quiz.

2/28/2008 Algebra 1 - Scientific Notation

We reviewed scientific notation today. The four types of exercises we did were:
1) Rewriting numbers in scientific notation
2) Writing number in scientific notation as regular numbers
3) Multiplying scientific notation numbers together
4) Dividing scientific notation numbers

Students took some notes over some example problems and then worked on the assignment.
When they were finished they turned it in and we took a quiz.

Today we reviewed our notes and did a review activity for points (p. 804 46-58).  Then we took a quiz over exponential growth and decay.

2/26/2008 Algebra 2 - Solving Radical Equations



Welcome back after our holiday weekend and snow day! The blog is back in action after a layoff since Thursday. Today in Algebra 2, we continue with Chapter 7. We will be solving radical equations today. Radical equations are equations that contain a root or fraction exponent of some kind. Above, you can see a simple example of how to solve one of these. Students will take notes, as usual, in class showing some example problems and how to solve them. After some discussion and a few practice problems at the board, students will work on the graded assignment. Below is another example of how to solve a radical equation. This one has a root on both sides of the equation.

2/21/2008 Pre Algebra - Similarity and Measurement

We will review similarity and measurement again today.  I will provide students with some structured notes and we will go through the examples together, step by step, and solve them. They will then do some practice problems on their own and take a Quiz over the material.

2/21/2008 Algebra 1 - Exponential Growth


Today students were introduced to the idea of exponential growth. We talked about how exponential growth functions have a constant growth rate, but the amount that it is growing by differs. The picture above shows an exponential growth model. Students will be looking at problems modeling population growth and compounding interest to model exponential growth.

Homework:

2/21/2008 Applied Geometry - Law of Sines and Cosines



Above you can view a screencast of a problem solved using the Law Of Sines. We will be solving problems like this in class and on our homework today. You can view the Law of Sines here. We will also be working with the Law Of Cosines as well, which can be explained here. You will most likely have to use your notes later on to solve these, the Law Of Cosines is particularly long. Make sure they get copied into your notes along with the example problems on the board. In class today, after the students take notes, we will do some examples of solving for pieces of triangles using both the Law Of Sines and the Law Of Cosines.
