Welcome back to Week 22 at Knox Middle School!  This week we will begin Chapter 8 - Metric Measurement, Perimeter, Circumference and Area.  Students will need a ruler or protractor.  Students will also have a take-home test (from textbook) on Chapter 7 on Tuesday, February 9, 2010.  Next week, we will begin our Asian Culture Thematic Unit in the Computer Lab.  Students will work in groups of 3 or 4 as roommates.  The assignment will include creating a pie chart of their monies spent (converted from American to Asian currency) in a spreadsheet program; budget that provides documentation and graphics of monies spent for housing, food, clothing, and transportation in Comic Life.  Students will take the 7th grade writing test this week!!

We will also use Study Island and complete our 7th grade math  pre-test!  Parents, you can visit www.studyisland.org to get more information about this student-centered remediation program by using your child's login information! Report Cards were sent home with students on February 4, 2010, in Thursday folders! 

February Students-of-the Month coming this week...

R - Right or lame (Read the entire problem)

A - Apply your game (Are the important cue words circled)

A - Analyze, identify (Apply the steps to solve the problem)

V - Verify, please verify (Verify your answer to see if it's reasonable)

E - Evaluate your correction (Eliminate the wrong answers)

L - Look at your selection (Let your answer stand or rework the problem)

U - N - R - A - A - V - E - L!!

MESSAGE TO PARENTS

Please check your child's agenda for homework assignments, tests, and upcoming events!   Ask your child about Larry Bell's 12 powerful words:  Trace, Analyze, Infer, Evaluate, Formulate, Describe, Support, Explain, Summarize, Compare, Contrast and Predict!!  Some students received student contracts, please inquire with your child about this contract that was sent home on Friday, January 15, 2010!

7th Grade Math 

In accordance with the North Carolina Math Pacing Guide – Grade 7 (2009-2010), we will utilize the Holt Middle School Math, Course 2 Text Book for the North Carolina Course of Study.  Following are the topics we will cover:  Data Analysis, Number Sense and Algebraic Reasoning, Operations and Equations with Integers and Rational Numbers, Proportional Reasoning, Percents, 2-Dimensional and 3-Dimensional Geometry, Probability, Solving Equations and Inequalities, Functions & Sequences.  The course is required for graduation and does have an End of Grade test.  We will have fun and learn at the same time! 

HOMEWORK HELP

I have given students my email address for additional support, and they are allowed to work in their assigned study groups.  Please check your child's notebook for notes from class that will provide examples and assistance to them.  Every homework assignment is reinforcement for what I have modeled and demonstrated in class!                    

Perimeter is the total distance around a shape.  You calculate the perimeter by adding the lengths of each side of the shape.   B = base, H = height, l = length, w = width.

Perimeter of a Square (see below)  A square is a 4-sided polygon in which all the sides are the same length. Therefore, to find the perimeter of a square, we have only to multiply one side by 4. The formula for the area of a square is 4×s , where s is the length of a side.

When all the sides are the same length, multiply the number of sides times the length of one side. Perimeter of this square is 4 x 5cm = 20 cm

Perimeter of a Rectangle

A rectangle is a 4-sided polygon in which opposite sides have the same length and all angles have the same measure. Since opposite sides have the same length, we have only to add the lengths of two adjacent sides and multiply by 2 (so each side is "counted" twice). The formula for the perimeter of a rectangle is 2×(h + w) , where h and w are the height and width of the rectangle. For example, the perimeter of the rectangle below is 2×(3 + 6) = 2×9 = 18.

Area is the amount of surface a shape covers.  The area is measured in square units.  (See Example below)
