This week we will begin unit 3. We are learning that a ratio is a comparison or relationship between two numbers with division. Ratios look like fractions. Rates are ratios in which the two numbers have different units. When we express a rate with a denominator of one, the rate is also called a unit rate. For example, we use unit rates tell us a cost per item at the store or miles per hour of a road trip. Here are some resources we will use in class:
This week we will review for the unit 2 test which will be on Thursday, November 8th. Since Tuesday is a student holiday, we only have Monday and Wednesday to review. Students should review their old quizzes and practice problems from the study guide. They should also complete these two homework quizzes:
Directions: Go to quizizz.com and put in the game code. Sign in with your first name and first letter of your last name. If you want to try the quiz a second time, use the same sign in name followed by #2.
One and two step equations: Game Code – 609408 (This quiz ends on Wednesday night.)
Inequality concepts and equations: Game Code – 094761 (This quiz ends on Thursday night.)
This week we will learn to solve one step equations with integers. We will practice using a balance simulation on the computer. To use the activities, you must put in the password we used in class:
One step equations with algebra tiles – Explore – Put your own equations in the activity.
This week we will practice a little more with combining like terms and we will learn to use the distributive property to go between an expanded form and grouped form of algebraic expressions.

The Distributive Property – (Only watch the first 6 minutes and 45 seconds)
This week we are beginning unit 2. Students will learn the following algebra vocabulary words:
- Algebraic expression
- Numerical expression
We will practice using the School Yourself website. Students will need to use their username and password from class.
1) What is a variable? (A number we don’t know) – Go to Algebra, then Solving Equations, and Solving for unknowns – or https://schoolyourself.org/learn/algebra/number-line-solve
2) How do we solve expressions? (Substitute a number for a variable) https://schoolyourself.org/learn/algebra/evaluate
3) What is a coefficient? (The number in front of a variable) https://schoolyourself.org/learn/algebra/coefficients
4) How do we simplify expressions? (Combine like terms) https://schoolyourself.org/learn/algebra/simplify
This week we are reviewing decimal operations and applying our knowledge to completing problems with positive and negative decimals.
This week we will apply what we have learned about adding, subtracting, multiplying, and dividing integers to completing problems with fractions. Any classwork that is not finished in class is homework.
Monday: Simplifying Fractions
(Review finding prime factors if you forgot!)
Wednesday/Thursday: Adding and Subtracting Fractions
Here are two ways to find common denominators: Easy common denominator (ECD)
Friday: Fractions Assessments – Use your notes, classwork and videos above to review.
This week we are learning to use the order of operations with absolute values and to multiply and divide integers. Here are some video resources:
Students who make less than an 80% our last assessment should watch the adding and subtracting video and complete my recovery packet. Next they should come in for tutoring and re-take the quiz. Students can always come to tutoring if they need help with classwork/homework or feel they don’t understand a topic. My tutoring is on Tuesday afternoons until 5 pm and Thursday mornings from 8:15 to 8:45.
This week we are reviewing positive and negative integers and absolute value. We are learning to add and subtract integers on a number line and with rules. Here are some of the resources we are using this week:
