How to Study in Math
Resources for studying:
-
Go back and try the questions again on your quizzes. Find your mistake and learn from them.
-
Redo questions from your notes.
-
Read through the Power Points and do the questions in them.
-
Watch personal tutor videos from the textbook's website.
-
Watch videos on Khan Academy. Type in the topic to the lesson and I'm sure related videos will come up.
-
Do the practice tests in the textbooks - ask me for the answers.
-
Choose questions from the study guides for each lesson. Skip around on the worksheet to get different types of questions without having to do all of them. The ones at the end of each section are the hardest so if they are easy, try to last few in each section to challenge yourself.

Studying for the Chapter 2 Test
Do the practice test and check your answers.
Practice any of the IXL's from Chapter 2.
Don't forget, revisit your past homework worksheets and quizzes from this chapter. Maybe things that you didn't know how to do at the time, you might be able to do now!
Classroom Review Activities
Multi-Step Equations Partner Problems
CHAPTER 1 & 2
Work with 1 other person.
One person does the questions on the left, the other person does the questions on the right column of the sheet.
You have different questions, but your answers will be the same for each problem number. If you get the same answers you know you did it right. If you get different answers, analyze each other's work until you both get the same number for the answer.
Activity takes about 20 minutes.
One-Step, Two-Step Equations Worksheet (The one with boxes)
CHAPTER 1 & 2
This worksheet summarizes different types of equations we learned to solve in chapters 1 and 2.
Do this independently, but ask other people for help when you need it.
Be sure to check your answers!
This review takes about 10-20 minutes
Equation Maze
CHAPTER 1 & 2
Solve the equation in the box that says "start"
Look to see if the answer you got is one of the ones branching off that box. If it is, circle that answer and go to the next box it leads you to.
You are finished when you get to the "end" box. Not all boxes will be used.
Check your answers when you are done!
This activity takes about 10-20 minutes.
Stations Maze
CHAPTER 1 & 2
Start at a station, copy down what station number you started at.
Do the question and look for the answer in the choices. The answer tells you what station to go to next.
Repeat this process by doing the questions and going to the stations it tells you to until you are back where you started at. You will go through 10 stations.
Be sure to copy down the station numbers you go to so you can check your answers at the end to see if you did them in the right order.
