So if we have a sentence that tells us that two phrases are equal, we can translate it into an equation. We look for clue words that mean equals.

Some words that translate to the equal sign are:. It may be helpful to put a box around the equals word s in the sentence to help you focus separately on each phrase. Then translate each phrase into an expression, and write them on each side of the equal sign. We will practice translating word sentences into algebraic equations. Some of the sentences will be basic number facts with no variables to solve for.

Some sentences will translate into equations with variables. The focus right now is just to translate the words into algebra. Solution The location of the word is tells us that the equal sign goes between 7 and We will solve the equations by using the Subtraction and Addition Properties of Equality. Note that this is different from the written examples on this page because we start with the mathematical equation then translate it into words. Skip to main content.

Show Solution Solution The location of the word is tells us that the equal sign goes between 7 and Recognize the key words: twice; difference of …. Twice means two times. Licenses and Attributions. CC licensed content, Original.Students walk into class and pick up the packet for the day. They get to work quickly on the problems. Often, I create do nows that have problems that connect to the task that students will be working on that day.

For this lesson I want students to practice change expressions from word form to numerical form before we start working with algebraic expressions.

To check the do now, display answers from 1 a — h. I ask students to share with their partner which number sentences result in the same answer. After a minute of sharing, I ask students to share out. I want students to share that a and b have the same answer as well as g and h. I call on students to share their mathematical thinking.

In the past I have found that many students mistakenly think that problems like and as well as 2 divided by 1 and 1 divided by 2 are equivalent. I want to address those misconceptions in the do now before moving on to algebraic expressions and equations. I ask students to share out one thing that they wrote down on their do now that will help make today a productive math class.

I tell students that they will be connecting their knowledge operations to algebraic expressions and equations. I call on students to read the vocabulary words and the examples. Students have to copy each example in the appropriate column, expression or equation, and then identify coefficients, constants, and variables.

I am walking around and making sure students are on task and that they are using their notes to correctly identify the vocabulary words.

We will address any questions or misunderstandings. Here students are using MP3: Construct viable arguments and critique the reasoning of others. I tell students that in algebra they are going to be using variables to represent a situation. Before we model situations using variables, expressions, and equations we need to be able to translate expressions and equations between word form and algebraic form.

I write example 1 and 2 in algebraic form. We go through the table and I ask students to identify which operation matches which group of expressions.

I then show students the different ways to represent those expressions parentheses, dot, fraction bar, etc. I stress that the order of the variable and the number matter for division and subtraction.

I mention the do now problems where we showed that the quotient of two and one is different than the quotient of one and two.

How can write an expression to represent them? Many students struggle that these phrases are represented by n and not 12 — n, the way that the values appear in the phrase.

Palmer has n dollars. Eric has 12 dollars less than her. How much money does Eric have?In the previous section, we listed many operation symbols that are used in algebra, and then we translated expressions and equations into word phrases and sentences.

They are summarized below. Each phrase tells you to operate on two numbers. Look for the words of and and to find the numbers. Solution 1. The key word is differencewhich tells us the operation is subtraction.

Look for the words of and and to find the numbers to subtract. The key word is quotientwhich tells us the operation is division.

They tell us the operation is subtraction. There are two operation words: times tells us to multiply and sum tells us to add. To take a sum, we look for the words of and and to see what is being added. In part 1, we add first and in part 2, we multiply first. Write an expression for the height of the window. Blanca has dimes and quarters in her purse. Write an expression for the number of dimes. Skip to main content.

CC licensed content, Original.You've learned how to work with variables and how to evaluate algebra expressions, now we are going to translate words into algebraic expressions. This skill will come in handy when working with word problems or real life situations.

Pay close attention to the "key words" that represent mathematical operations. The good news is that these very same words that we use to write numerical expressions are going to be used to write algebra expressions. The difference between a numerical expression and an algebra expression is that we will be using variables when writing an algebraic expression.

Instead of "8 plus 9" with two given numbersyou would see, "a number plus 9". We don't know exactly "what number", so we would use a variable to indicate that it can be any number.

Key words for each operation are indicated in bold. This will help you to easily translate the expression. As, you can see from the red, bold words, the key words for addition are: sum, more than, plus, increase, add, older than.

Please also remember that addition is commutative; therefore, you can reverse the digits and you will end up with the same answer. Our key words for subtraction are: minus, less, subtract, decrease, younger than, and lowered. Remember that subtraction is not commutative, so the order in which write the digits does matter! The key words for multiplication are: times, product, twice, doubled, multiplied, and of.

Of is the tricky word. This is mostly used when you are multiplying a fraction times a number. The last operation that we will study is division. Division is not commutative, so you must pay close attention to the order in which you write the expression. Division is much more simple.

The key words are: divided by and divided into. Play close attention to the order in which it is written. As you begin to work with algebraic expressions more, you will see word problems that require you to use more than one operation.

Many people struggle with translating word problems into algebraic expressions.

This is a very brief lesson on simple algebraic expressions. One of the most important things to remember is to look for key words and to make sure that your expression matches the context of the word problem.

This is most important for operations that are not commutative, such as subtraction and division. The next lesson in this unit is on simplifying algebraic expressions.

Math Worksheets. More Information.Recovering from a collapse as monumental as the one Atlanta suffered last February could take years, not months. The Silver and Black are the trendiest of trendy picks to dethrone the Patriots in the AFC and make a triumphant return to the Super Bowl their first since 2003. For that to happen, Derek Carr must take another step toward elite status, and a rising defense led by reigning Defensive Player of the Year Khalil Mack must plug the leaks that plagued them in 2016.

However, a 12-4 record has raised expectations to meteoric levels. And with that comes increased pressure. But at this price. Is Trevor Siemian still the starting quarterback. Then stay away, even at this price.

Dynamic weapons in the passing game. Two-time Super Bowl winner at quarterback. On paper, Big Blue looks like a good bet. Those two titles Eli won were behind power rushing attacks. Intriguing team with a hellish defense coming off a 12-4 AFC West title. Trusting either Tom Savage or rookie Deshaun Watson to lead the Texans to the promised land is like tossing money into a fire pit.

Not that long ago the Cats were 17-1 and representing the NFC in the Super Bowl. Cam Newton coming off a dreadful 2016 is eager to prove last year was a fluke.

Toss in rookie Swiss Army Knife Christian McCaffery and a stout front seven, and there should be a significant level of interest. Especially at this price. If Atlanta regresses, look out. Young, talented team with a gunslinger at quarterback, a pair of playmaking receivers, and an attacking defense. The last two NFC champs came from the AFC South. Punting on either of these teams is worth considering at this price.

Drew Brees knows time is running out on making another Super Bowl run. Perhaps the addition of Adrian Peterson will give the Saints the boost they need to overcome obvious defensive flaws. As for the Birds, nobody ever wins the NFC East in consecutive years, and the hype surrounding Carson Wentz seems to be legit. If the Eagle defense can elevate to Top 10 level, it might be enough to carry them into January.
