Study Strategies
Letâs face it: becoming good at math takes work. Not only do you have to study; you have to study hard. But studying hard isnât enough. If youâre studying the wrong way, all of your work is not going to pay off. After all, practice only makes things permanent, but practicing the right way makes them perfect. This means that if youâre practicing incorrectly, youâre just cementing bad habits into place. Thatâs actually even worse than doing nothing! And you certainly shouldnât waste your time doing work that isnât helping. Before you start learning all the details of pre-algebra math, it is important to review how to study pre-algebra. This chapter will give you some ideas as to how you can effectively study so that you can use this book in the way thatâs most helpful to you. Your goal should be to pick up a few pointers, so that when the quiz or test or final comes along, youâll be able to show what youâve learned!
Donât Call Yourself âBad at Mathâ
All students encounter subjects that come naturally to them and concepts that they find a little bit harder to understand. It can be really frustrating to work on something when you feel like the people around you donât have to work quite as hard. But the fact of the matter is that youâre reading this book because you have to learn math. Whether itâs to get ready for high school or to pass a college course, learning pre-algebra is a step you have to complete to get where you want to go.
Most people who believe they are âbad at mathâ usually have one or two concepts that they didnât completely understand somewhere within their math education, whether those steps were in second grade or in middle school. When that happens, they have a weak foundation. And when they start trying to build other stuff on top of that foundation, it doesnât go very well. That doesnât mean they are bad at math. It just means they have to find the area or areas they donât really understand and spend a little time fixing the foundation in that area.
Donât ever say you âcanât do math.â Can you split a bag of candy in half? Can you figure out how much money two things will cost when you know the price of each one? Can you calculate how much money youâll earn this month if you earn $5 every day? Then you can do math. Math on paper (and in class, on quizzes, and on tests) is just a code that represents what happens with numbers in the real world. Learn the code, one piece at a time, and youâll be able to do it.
Ask for Help
This is one of the most important actions you can take, because itâs something that students donât often think to do. Asking for help doesnât mean that you canât do it yourself. It doesnât mean youâre stupid. It doesnât mean you donât know what youâre doing.
What it means is that youâre a good student. Good students ask for help, wherever they can get it. Thatâs how you learn. The people who learn the most in life are the ones who ask questions.
Whether youâre totally lost, or you just have one little question, get an answer. Math builds on itself, and if there is a hole in your understanding, your foundation for future topics is going to be weak. Ask your classmates. Ask your older brother or sister. Ask your parent or tutor. Ask in a forum online. And, of course, ask your teacher! Donât just ask the day before the testâask as soon as the problem comes up.
Explain It to Someone Else
Sometimes you hear your teacher explain a concept in class, and it makes perfect sense. Then you get home to do your homework, and you just canât figure out how to get to the answer. Other times, it doesnât make sense even during class, but everyone else seems to get it.
If you think you donât understand a concept, try explaining it to someone else. Maybe youâll be able to explain it, and then youâll see that you really do understand it. If not, youâll be able to clarify what it is that youâre having trouble with, because it will be where you get stuck during the explanation. Explaining is a way to make sure you understand the reasoning behind each step. When you understand the reasoning, youâll really understand whatâs going on. Thatâs the road to success.
This is really hard to do, but it works. Itâs much harder to try to explain something than to have it explained to you, because it makes you vulnerable. But donât be afraid to make a mistake: this is an excellent way to learn. Try to explain to someone who already knows the material so that he or she can tell you if youâre making a mistake and help you when you get stuck. Give it a try!
Take It One Bite at a Time
Some math problems involve using ten or twenty different skills. It looks like one problem, but it has a whole series of intricate steps and skills that have to be done correctly to get the right answer!
If you are having trouble, break the problem down one step at a time to see if you can catch where your mistake is occurring. Maybe you actually understand the concept, but youâre making an arithmetic mistake. Maybe you are doing all the arithmetic right, but you donât understand exactly what the question is asking you to find. If you can figure out which step youâre having trouble with, you can get a better explanation, re-read your textbook, or do some more practice problems of the same type.
Cement Good Habits
Doing something correctly once is not enough to say that you know it. Itâs proof that you can do it, but itâs just a start to really learning. Once youâve learned something, you know how to do it when it shows up again.
That means that you have to practice the steps you take to solve a problem enough times that they are consistent and comfortable in the future. The best way to practice math is to practice in short, frequent study sessions. When you try to cram while learning a skill, you donât get the most out of the problems. If you do thirty of the same problem type in a row, you are really only thinking on the first one; after that, youâre basically copying what you did on the previous problem. But if you do ten problems today, and then ten again tomorrow, and then ten later in the day, you will probably remember the steps much more clearly.
Math is a skill, and itâs best learned the way you learn other skills, like playing a sport or a musical instrument. Just like you canât abstain from exercise all week and then complete eight hours of football practice on Sunday without an issue, you really shouldnât try to cram for math.
Try It with Numbers
The biggest difference between pre-algebra and the math youâve done before pre-algebra is the presence of variables (letter symbols that represent quantities in math). Sometimes itâs hard to learn too many new things at once, and the variables can be just an added burden. So, try replacing the variables in a problem with numbers, and see if you can make sense of it that way!
When it comes to understanding new concepts, practice them with numbers first, and see what happens. Look at the solution and see what the variable equals, and then plug that answer in for the variable. Then, try manipulating the equation or expression so that you can understand how the numbers relate to one another. It might help you understand the rules...
