Quiz on Tuesday

Next Tuesday we will take a quiz on formulas. There will be questions that involve Area, Perimeter and Volume (the formulas will be given), though for some questions you may need to solve for one particular dimension, thus turning the problem into an equation (like we've been doing in class). There will be one additional formula given for which you will need to plug in the values and solve.

Remember the steps:
1. Plug in the values for each variable.
2. Solve for the unknown (whichever variable is left).

In some cases, this means you will be left with a 2-step equation; remember to "get rid of the loner" first, and then solve by completing the opposite operation. Be sure to look over the page from 2-9 in your workbook as you review. We will be practicing more tomorrow and on Monday.

Solving 2-Step Equations

Remember when solving equations to take care of the "loner" first. (Do the opposite operation to both sides.) Then, solve just like you would for a one-step equation by isolating the variable. If you find that the operations are confusing or seem a bit clumsy, complete KFC before solving.

Here's a good infographic to demonstrate (borrowed from http://mrsflansms.weebly.com/):

Midterm Study Concepts

Here are the four major study concepts we will focus on for our midterm:

1. Integer Operations

2. Coordinate Plane

3. Simplifying Variable Expressions

4. Solving Equations (all operations)

We will be reviewing all week in class and adding to our study guides. Your best resources for study will be your previous quizzes and tests. Don't forget to practice with ixl - you have completed these concepts online already, but ixl will allow you to go back and re-practice.

Quiz Thursday

Hello! This is just a reminder that your quiz on Thursday will include equations with all operations (adding, subtracting, multiplying, and dividing). Remember that your objective is to isolate the variable, and this is accomplished by performing the opposite operation to both sides. Be sure to look through your notes before your quiz. It will also include integers and absolute value. Tomorrow we will play a review game. Happy studying!

Least Common Multiple

A few reminders for LCM:

A multiple is the product of two numbers. 10 is a multiple of both 2 and 5, for example. Be careful not to confuses multiples with factors.

When finding the LCM using prime factorization, use each match only once, and then bring all the other numbers "down to the party."

If you are finding the LCM of three numbers, your common factors ("matches") do NOT need to be found in all three numbers to be considered a match.
