Translating Words into Algebraic Expressions: Free Guide

Translating Words into Algebraic Expressions

Welcome to this complete guide to translating words into algebraic expressions (also known as algebraic translation), where you will learn how to identify and apply key information, in the form of words and phrases, to accurately translate a given set of words into an algebraic expression involving both numbers and variables.

Why is learning how to translate words into algebraic expressions a crucial skill that every math student must learn? Because it is often the case that math problems are expressed completely in words without any explicit use of numbers, expressions, or equations. In order to solve these types of math word problems, students have to be able to translate words into expressions or equations so they may model and solve such scenarios.

Are you ready to learn everything there is to know about algebraic translation?

The following free Translating Words into Algebraic Expressions lesson guide is a step-by-step tutorial that will teach you how to easily and accurately translate any given word phrase into a mat equation.

How can you translate written expressions into numerical form?

The key skill associated with algebraic translation is being able to rewrite mathematical situations expressed in words as a mathematical expression involving numbers, operations, and variables.

Before we get to actually translating words into algebraic expressions, let's lay some important groundwork!

Tip #1: Expressing Variables

For example, what if we wanted to translate the phrase the sum of seven and five into an expression. It would be pretty easy to translate this phrase into 7 + 5 and your job would be done.

But what if we changed the phrase to the sum of a number and five? How would our numerical expression change? Since a number could represent any value, we have to use a variable (since a variable can represent any value).

In this case, you could translate the sum of a number and five into x + 5 where x represents a number.

When using letters as variables in a math expression or equation, x is the most commonly chosen letter, but you can actually choose any letter to represent an unknown value.

Example A: Translate the phrase ten plus a number into an algebraic expression.

To complete this translation, we can break the given phrase down into three parts:

I: ten ➔ 10

II: plus ➔ +

III: a number ➔ x

Now, you can translate ten into 10, plus into an addition sign, and a number into a variable leaving you with:

ten plus a number ➔ 10 + x

Tip #2: More Than/Less Than

Now, let’s slightly change the words given in Example A as follows:

Example B: Translate the phrase ten more than a number into an algebraic expression.

You probably already know that more than is associated with addition so the sign is not going to change. But what about the order of the terms?

Think about it this way: we have a number (some unknown value) and this phrase represents ten more than whatever that value is. So, in this case, you will start with the variable first and then add ten to it as follows:

ten more than a number ➔ x+ 10

You would be correct to wonder whether or not the order of the terms matters in this example. Technically, it does not because addition is commutative. But what about subtraction, which is not commutative?

See Also: The Commutative Property: Everything You Need to Know

Example C: Translate the phrase six less than a number into an algebraic expression.

Notice again that we are seeing the word than.

You probably already know that less than is associated with subtraction so you already know what sign you will be using.

This phrase represents a value that is six units smaller than whatever our unknown value is. So, to find that number, we would have to take our variable and subtract six from it as follows:

six less than a number ➔ n-6

In cases like Example B and Example C, the second term comes first and the first term comes second (you have to switch the order).

So, we can conclude that than is a switch word, which means that the operator in the middle stays the same, but the first term and the last term are switched. Look out for this relationship when you see the phrase more than or less than in words.

Tip #3: Groupings and Parenthesis

Let’s move onto another example…

Example D: Translate the phrase the difference of three and a number into an algebraic expression.

Translating this phrase into an expression should be pretty straightforward.

Since difference means subtraction, we can easily perform the following algebraic translation:

the difference of three and a number ➔ 3 - p

Now, what if we changed this expression to the difference of three and twice a number plus one

Example D: Translate the phrase the difference of three and twice a number plus one into an algebraic expression.

So, now instead of 3 - p, we have to write the expression as 3 - the entire expression twice a number plus one, which we can call 2p + 1.

Note that you will have to use parenthesis to enclose the entire expression twice a number plus one as follows:

the difference of three and twice a number plus one ➔ 3 - (2p+1)

So, whenever you are performing algebraic translations, you can use parenthesis to separate independent groupings.

Associative Property of Multiplication Explained in 3 Easy Steps

Associative Property of Multiplication Definition

In math, the associative property of multiplication is a rule which states that the groupings of values or variables being multiplied together does not affect the product or outcome.

The associative property of multiplication can help you to model and solve simple and complex multiplication problems. This rule is a fundamental law in mathematics and applies to any multiplication problem.

The following guide to understanding and applying the associative property of multiplication will share a step-by-step tutorial as well as a free associative property of multiplication worksheet.

Let’s start off by looking at a few examples…

Associative Property of Multiplication Example

Take a look at the equation above:

(a x b) x c = a (b x c)

Notice that the terms (a, b, and c) are in the same order, but grouped differently. On the left side of the equals sign, a and b are in parenthesis. On the right side of the equal side, b and c are in parenthesis. And, according to the order of operations, you must perform operations inside of parenthesis first.

So, according to the associative property of multiplication, the left side of the equal sign and the right side of the equal sign will always equal the same value, no matter what values a, b, and c represent.

Now, let’s go ahead and explore why the associative property proves this equation to be true by substituting numerical values in for a, b, and c:

a=8, b=4, c=2

Step One: Follow the order of operations by performing multiplication inside of the parenthesis first.

In this example, perform (8 x 4) on the left side of the equation and (4 x 2) on the right side of the equation as follows:

(8 x 4 ) x 2 = 8 x (4 x 2)

32 x 2 = 8 x 8

Step Two: After working out the products inside of the parenthesis, the next step is to multiply the next line of the equation. In this case, 32 x 2 on the left side, and 8 x 8 on the right side.

32 x 2 = 8 x 8

64 = 64

Step Three: Verify your answer.

Remember that, according to the associative property of multiplication definition, the groupings of values or variables being multiplied together does not affect the product or outcome. Therefore, the left side of the equation and the right side of the equation should equal the same value.

In this example, the associative property holds true since both sides of the equation are equal to 64.

Associative Property of Multiplication Example Recap:

(8 x 4 ) x 2 = 8 x (4 x 2)

32 x 2 = 8 x 8

64 = 64 ✓

What About Division?

Now that you understand the associative property of multiplication, let’s see if the inverse of multiplication—division—is also associative.

What if we reused the associative property of multiplication example from before, but changed the multiplication signs to division signs?

Just like the last example, a=8, b=4, and c=2, the order of the terms is the same on both sides of the equal sign, but the terms are grouped differently. And also notice that the operation is no longer multiplication, but division.

Step One: Follow the order of operations by performing division inside of the parenthesis first.

In this example, perform (8 ÷ 4) on the left side of the equation and (4 ÷ 2) on the right side of the equation as follows:

(8 ÷ 4 ) ÷ 2 = 8 ÷ (4 ÷ 2)

2 ÷ 2 = 8 ÷ 2

Step Two: After working out the quotients inside of the parenthesis, the next step is to divide the next line of the equation. In this case, 2 ÷ 2 on the left side, and 8 ÷ 8 on the right side.

2 ÷ 2 = 8 ÷ 2

1 ≠ 4

Step Three: Verify your answer.

Remember that, the associative property states that different groupings of the terms in an equation should not change the result. In the first example, we proved that the associative property works for multiplication since both sides of the equation equaled the same number (64=64).

However, in the division example, we see that the left side of the equation and the right side of the equation result in different values. In this case, 1 and 4, which are obviously nit equal.

Therefore, in this example, the associative property does not hold true for division since both sides of the equation are not equal.

Associative Property of Division Example Recap:

(8 ÷ 4 ) ÷ 2 = 8 ÷ (4 ÷ 2)

2 ÷ 2 = 8 ÷ 2

1 ≠ 4 ✕

Conclusion: Associative Property Math Facts

The previous example has shown us that the associative property works for multiplication, but it does not work for division.

Therefore, as long as all of the terms are being multiplied (not divided), the groupings of values or variables being multiplied together does not affect the product or outcome.

So, (a x b) x c = a x (b x c) for any real number values represented by a, b, and c.

Key idea: The associative property of multiplication can be applied when the terms are in the SAME ORDER, but GROUPED DIFFERENTLY.

Number Bonds Explained: Free Worksheets Included

What is a Number Bond?

Number Bond Definition

What is a number bond? A number bond is a simple visual math aid that is used to show a given number can be represented as the sum of two numbers.

Do you want free K-8 math resources in your inbox every week? Click here to join our mailing list

Number Bond Example: 5

Let’s take a closer look at the number 5. You know that the number 5 can be thought of as the sum of 4 and 1, the sum of 3 and 2, or the sum of 5 and 0. In terms of number bonds, these different ways of expressing the number 5 as the composite sum of two numbers can be visually represented using number bonds as follows:

And, since addition is commutative, meaning that the order of the terms does not matter (e.g. 2+3=5 and 3+2=5), you can also express the above number bonds in reverse order as follows:

Now that you understand what number bonds are and what they represent, it’s time to explore why they are such a useful tool for helping your students to develop strong number sense and fluency with performing operations on numbers.

For starters, the visual nature of number bonds is an excellent way to help students to conceptualize numbers and how they can be expressed as a composite sum of two numbers. By understanding this composite nature of numbers, students are better equipped to perform mental math quickly and accurately and perform advanced operations.

 For example, imagine a student becoming familiar with the following number bonds for 10:

With this understanding, a student could easily and accurately solve an expanded addition problem by combining terms that equal 10 as follows:

Number Bond Example: Number Bonds to 10

Now that you understand the value of having your students practice and understand number bonds, you can start by focusing on number bonds to 10. The diagram below shows the number bonds to 10.

Subtraction Number Bonds

Everything related to number bonds that we have covered so far have related to the fact that number bonds represent how a number can be expressed as the sum of two other numbers. But what about subtraction? We know that addition and subtraction share an inverse relationship. This inverse relationship can be explored via number bonds (note that this is an advanced step that should not be explored until your students have completely mastered the number bonds to 10 and possibly beyond.

Number Bond Example 03: Subtraction

For example, how could a student use her understanding of number bonds to solve the problem 10 - ___ = 7?

In this example, the student knows that one of the number bonds for 10 includes the number 7 and that the other number is 3 (because 7+3=10).

With this understanding in mind, it is a logical conclusion that 10 – 3 = 7 meaning that the missing number is 3.

This answer may seem extremely simple to find and you may even think that the use of a number bond is not even necessary. However, if we rewrite this problem as:

10 – X = 7 where x=3

We can see how understanding number bonds can apply to more advanced problems including high school level algebra.

Observe the diagram below that represents this application of subtraction number bonds:

Conclusion

Number bonds are simple visual tools that are used to show how a number can be represented as a composite sum of two other numbers. A number bond includes a whole number with two branches stemming from the number and leading to the two other numbers whose sum is equal to the original whole number. Number bonds are a valuable visual tool for helping students to practice and develop number sense, which is a critical foundational math skill that students will need to be successful at higher level of mathematics.

Free Multiplication Chart Printable PDF

Are you looking for a free multiplication chart printable to use as a practice aide for learning your times tables? If so, this post shares some helpful information on how you can use a blank multiplication table to learn your multiplication and times tables facts quickly and efficiently. You can also download a free printable 12x12 multiplication table chart that you fill in on your own.

Before you get started, it’s important that you understand some key information relating to multiplication charts and times tables. Let’s quickly focus on answering three key questions (understanding the answers to these questions make learning your multiplication chart facts much easier and will save you lots of time in the long run).

• How do you read a multiplication chart? How do you read a multiplication table?

• Why does the order of the terms not matter in multiplication?

• What should you always be looking for when filling in a blank multiplication chart?

(Do you want more free math resources and activities in your inbox every week? Click here to sign up for our free mailing list)

How do you read a multiplication chart? How do you read a multiplication table?

Multiplication charts and multiplication tables work like a Bingo board, where the number inside of each box represents the product of the corresponding column and row.

For example, 4 x 5 = 20

Now that you understand how multiplication tables work, you can fill in each box with the number that is equal to the product of the corresponding column and row.

Why does the order of the terms not matter in multiplication?

Since multiplication is commutative, the order of the terms does not matter.

For example, 3 x 7 = 21 AND 7 x 3 = 21

Notice that, even when the order of the terms is reversed (3 x 7 or 7 x 3), the outcome is the same since they both equal 21. This fact is always true when multiplying integers together.

Now that you understand that multiplication is commutative, you will have a much easier time completing your printable multiplication chart.

What should you always be looking for when filling in a blank multiplication chart?

Whenever you are filling in a multiplication table or multiplication chart, you should always be looking for patterns!

For example, take a closer look at the 5 times table and see if you notice any patterns…

The video is the perfect companion for sitting down and filling out your blank multiplication table until you are eventually able to fill it out completely on your own. After all, practice makes perfect! (We highly recommend printing out multiple copies of our blank multiplication table chart and filling them out until you no longer need a guide).

Conclusion:

Completing a blank multiplication table and using a filled-in multiplication chart as a reference is a great way to learn your times tables and your multiplication facts. We recommend printing out several copies of our blank chart and filling them out using our video lesson as a guide until you can fill out the entire table on your own. Then, you can use our filled-out reference table to help you while you work on problems.

Lastly, always keep these three ideas in mind whenever you are studying and/or learning your multiplication facts: (1) a multiplication table works like a bingo board where the number in each box represents the product of the corresponding row and column, (2) multiplication is commutative, which means that the order of the terms does not matter (example: 2x8=16 and 8x2=16), and (3) always look for patterns and relationships between the numbers (this will help you to always remember your multiplication facts!).
