Sixth Grade
There is a test tomorrow over central measures of tendency (mean, median, mode, and range) and graphing. You guys will do very well because our in class review has been terrific. Thanks for working so hard!
Seventh Grade
Math - Today, the class worked on their graphs from our zoo trip. They will finish up tomorrow and present their findings to the class.
Geography - The class took a test over Chapter 16 today. There is a country quiz tomorrow! (It's been awhile.) So be sure to study.
Eighth Grade
Pre-Algebra: We reviewed for the probability test, which will be on Wednesday. We will continue to review, but you should go over the review sheet tonight to be sure you understand all that we did today.
Algebra I: Completing the Square
Here are the steps:
Step 1: Get the x squared term and the x term on the left side and the constant term on the right side.
Step 2: Divide the coefficient of x by 2 and then square it.
Step 3: Add the result of step 2 to both sides. (Remember, if it's a fraction because the coefficient of x is an odd number, you will have to change it into a mixed number to add it to the right side.)
Step 4: Factor the left side. If the coefficient of x was an even number, this is an easy step. You should be able to see the factoring fairly easily. Just remember, what goes in the parentheses is what you got when you divided the coefficient of x by 2 before you squared it! Write the left side so that it's one binomial squared. ( ) squared. Also, if you have a mixed number on the right side, change it back into an improper fraction.
Step 5: Find the square root of both sides. Add a plus or minus sign in front of what you are square rooting on the right side.
Step 6: Get the x by itself by moving the constant term on the left side over to the right. Put this number in front of the plus or minus sign. If the right side works out when you found the square root of it, then you need to continue to solve and get your solution(s). If the right side still has a square root, you will be done. There are examples at Purple Math here.
