Upcoming tests

Math: Today we went over the computer lab activity and then had a worksheet to do in class on patterns. The assignment for tonight is p. 187, #19-36. We will review on two-step equations tomorrow and have a test on patterns and equations Thursday.

I found some websites that give you practice figuring out patterns.

Spy Guys Interactive - Summarizing/Extending Patterns - Click Skip Intro, then select Lessons, and then click on Lesson 8 (Although it says it's grade 6 stuff, we do it in grade 7 too.)

Mystery Operations - In this activity the computer makes up a mystery operation, and you have to figure out what the operation is. You give the computer two numbers to calculate, and it tells you the answer.

Number Cracker - Help Mr. Cracker obtain the secret code before the insidious Prof. Soup catches him by guessing what number comes next in a series of numbers. Start with the easy level and work your way up. The Super Brain level is really hard!

I want to thank Mr. K and Ellie for these sites!


Students had the opportunity to correct or finish the percents test from last week in class today. There are still a few students working on these.

Pre-Algebra: We reviewed sections 4,6,7, and 8 in Chapter 8 for tomorrow's test. There are still some students confused about slope and y-intercept. I have found some internet sites that might be helpful. Let me know what you think!

Math.com has a great lesson on slope and y-intercept that gives a first glance, in-depth, examples, and workout. There is also a lesson on graphing equations.

Here is a program that will help you visualize how changing the values for the slope, m, and the y-intercept, b, will affect the graph of the equation y = mx + b. At first the program will be automatically cycling through several values for m and b. If you want to use the sliders to control it yourself, just press the 'You Control' button.

This is a neat program that also allows you to explore slope and y-intercept. You can play for free for 5 minutes. You can also sign up for a free 30 day trial.

I found a mneumonic I had never seen for y = mx + b at this site. Extra credit for anyone who tells it to me!

The Math Forum has put together a cute explanation using Joan the Chameleon. It looks elementary, but it explains the concept very clearly.

The last one is an interactive tutorial for slope and y-intercept. Have fun!
