## How To Do Algebra Word Problems

When you take a real-world situation and translate it into math, you are actually ‘expressing’ it hence the mathematical term ‘expression’. Everything that is left of the equal sign is considered to be something you are expressing. Everything to the right of the equal sign is yet another expression. Simply stated, an expression is a combination of numbers, variables and operations. Expressions have a numerical value. Equations are sometimes confused with expressions. To keep these two terms separate, simply ask yourself if you can answer with a true/false. If so, you have an equation, not an expression that would have a numerical value. When simplifying equations, one often drops expressions such as 7-7 that equal 0.

A few samples:

 y – 12

## Draw A Simple Picture And Label It

Drawing pictures using simple shapes like squares, circles, and rectangles help students visualize problems. Adding numbers or names as labels help too.

For example, if the word problem says that there were five boxes and each box had 4 apples in it, kids can draw five squares with the number four in each square. Instantly, kids can see the answer so much more easily!

## Mixed Operations Word Problems

27. Mixing Addition and Subtraction: There are 235 books in a library. On Monday, 123 books are taken out. On Tuesday, 56 books are brought back. How many books are there now?

28. Mixing Multiplication and Division: There is a group of 10 people who are ordering pizza. If each person gets 2 slices and each pizza has 4 slices, how many pizzas should they order?

29. Mixing Multiplication, Addition and Subtraction: Lana has 2 bags with 2 marbles in each bag. Markus has 2 bags with 3 marbles in each bag. How many more marbles does Markus have?

30. Mixing Division, Addition and Subtraction: Lana has 3 bags with the same amount of marbles in them, totaling 12 marbles. Markus has 3 bags with the same amount of marbles in them, totaling 18 marbles. How many more marbles does Markus have in each bag?

## Determine The Operation For The Situation

Instead of key words, have kids really analyze the situation presented to determine the right operation to use. Some key words, like total, can be pretty vague. Its worth taking the time to dig deeper into what the problem is really asking. Get a free printable chart and learn how to use this method at the link.

## Underline Anything That Will Be Important For Setting Up The Algebra Equations Or Solving The Word Problem

When you have read through the entire word problem, you will want to go back through and underline anything important. This might include the keywords youve just found and any variables, as well as what your solution needs to be, so that you can set up the proper algebra equations.

When you underline or highlight these important parts, you can quickly reference the things you need to without having to read through the entire problem again. This makes it easier to go back and double check that youve got the right equations and variables set up, without losing your train of thought halfway through solving the algebra word problem.

## Real World Problems: How To Write Equations Based On Algebra Word Problems

I know that you often sit in class and wonder, “Why am I forced to learn about equations, Algebra and variables?”

But… trust me, there are real situations where you will use your knowledge of Algebra and solving equations to solve a problem that is not school related. And… if you can’t, you’re going to wish that you remembered how.

It might be a time when you are trying to figure out how much you should get paid for a job, or even more important, if you were paid enough for a job that you’ve done. It could also be a time when you are trying to figure out if you were over charged for a bill.

This is important stuff – when it comes time to spend YOUR money – you are going to want to make sure that you are getting paid enough and not spending more than you have to.

Ok… let’s put all this newly learned knowledge to work.

There are a few rules to remember when writing Algebra equations:

## Consider Teaching Word Problem Key Words

This is one of those methods that some teachers love and others hate. Those who like it feel it offers kids a simple tool for making sense of words and how they relate to math. Others feel its outdated, and prefer to teach word problems using context and situations instead . You might just consider this one more trick to keep in your toolbox for students who need it.

## How To Easily Make Your Own Math Word Problems & Word Problems Worksheets

Armed with 120 examples to spark ideas, making your own math word problems can engage your students and ensure alignment with lessons. Do:

• Link to Student Interests: By framing your word problems with student interests, youll likely grab attention. For example, if most of your class loves American football, a measurement problem could involve the throwing distance of a famous quarterback.
• Make Questions Topical: Writing a word problem that reflects current events or issues can engage students by giving them a clear, tangible way to apply their knowledge.
• Include Student Names: Naming a questions characters after your students is an easy way make subject matter relatable, helping them work through the problem.
• Be Explicit: Repeating keywords distills the question, helping students focus on the core problem.

Dont:

• Test Reading Comprehension: Flowery word choice and long sentences can hide a questions key elements. Instead, use concise phrasing and grade-level vocabulary.
• Focus on Similar Interests: Framing too many questions with related interests — such as football and basketball — can alienate or disengage some students.
• Feature Red Herrings: Including unnecessary information introduces another problem-solving element, overwhelming many elementary students.

A key to differentiated instruction, word problems that students can relate to and contextualize will capture interest more than generic and abstract ones.

## Ordering And Number Sense Word Problems

31. Counting to Preview Multiplication: There are 2 chalkboards in your classroom. If each chalkboard needs 2 pieces of chalk, how many pieces do you need in total?

## Look For Keywords In The Algebra Word Problems That Can Signal Which Operation You Will Be Doing

Algebra 1 Help: Solving Proportion Word Problems

These keywords can go a long way in helping you determine how to set up the algebra equations. Heres a list of some common keywords to get you started:

• Subtraction: decreased by, difference of, less than
• Multiplication: increased by a factor of, multiplied by, times
• Division: out of, per, ratio of
• Equals: are, gives, is, will be

Note that these keywords are not a complete list you will definitely see other words used to mean these operations, but keep in mind how the numbers and variables are positioned and what is being asked, and you should be able to add to this keyword list yourself!

Also, be sure to pay close attention to the relationship of the two variables when it comes to division and subtraction. It matters which variable comes first, and when the algebra word problem asks for the difference between x and y, when you write the algebra out, you will show x y. Likewise, the ratio of x and y written out will show x / y.

## Write On The Word Problem

This step reinforces the thinking which took place in step number two. Students use a pencil or colored pencils to notate information on worksheets . There are lots of ways to do this, but heres what I like to do:

• Circle any numbers youll use.
• Lightly cross out any information you dont need.
• Underline the phrase or sentence which tells exactly what youll need to find.

## Check Your Work When Done

This strategy goes along with the fifth strategy. One of the phrases I constantly use during math time is, Is your answer reasonable? I want students to do more than to be number crunchers but to really think about what those numbers mean.

Also, when students get into the habit of checking work, they are more apt to catch careless mistakes, which are often the root of incorrect answers.

A smart way to help kids conquer word problems is to, well give them better problems to conquer. A rich math word problem is accessible and feels real to students, like something that matters. It should allow for different ways to solve it and be open for discussion. A series of problems should be varied, using different operations and situations when possible, and even include multiple steps. Visit both of the links below for excellent tips on adding rigor to your math word problems.

## What Are Word Problems

A word problem is a math problem written out as a short story or scenario. Basically, it describes a realistic problem and asks you to imagine how you would solve it using math. If you’ve ever taken a math class, you’ve probably solved a word problem. For instance, does this sound familiar?

Johnny has 12 apples. If he gives four to Susie, how many will he have left?

You could solve this problem by looking at the numbers and figuring out what the problem is asking you to do. In this case, you’re supposed to find out how many apples Johnny has left at the end of the problem. By reading the problem, you know Johnny starts out with 12 apples. By the end, he has 4 less because he gave them away. You could write this as:

12 – 4

12 – 4 = 8, so you know Johnny has 8 apples left.
