This set of worksheets works on sums and differences found in word problem form.

This section focuses on math-based word problems that included some form addition and/or subtraction in some fashion. Each worksheet contains a number of different word problems for your students to solve. Activities include deriving the correct equations based on word clues and arriving at the correct answer. This usually will serve as students introduction to the concept of word problems. The more you switch between these two operations, the greater understanding of their use students will grasp. Many of the word problems students will come in contact with involve animals to some capacity. I always ask myself why, but who isn't into animals?

How to Identify a Word Problem That Requires Addition or Subtraction

Most word problems in math can be solved by using addition or subtraction. But how do you know which operation to use? This guide will show you how to identify a word problem that requires addition or subtraction and how to solve it.

A word problem in math is a problem that can be solved by using addition, subtraction, multiplication, or division. Word problems often include objects or numbers that represent other values.

When approaching these types of problems there are number of things that students are hazy on. The thing I encounter very often is that students get tripped up by focusing too heavily on the numbers themselves. They see the number and completely forget that the first thing you need to do is understand the mathematical relationship that is being expressed. I encourage students to block out the numbers right away. At that point we need to focus on keywords that explains the relationship that is present. Have students learn to answer if something is being added together or removed. It is helpful for students to build a math vocabulary of what word attaches to each of those operators. Once we have this down, it is time to bring the numbers back. Start by having students write a simple equation that explains the relationship. I will often practice dozens of problems with students by just having them writing these equations. Check that the equations are setup correctly. Remember with word problems it all about the process. I also find that many students benefit from making drawings about what is going on in each problem.

The key to identifying and solving these problems is remembering the keywords.

Keywords that indicate addition: together, sum, more, increase, combined, in total.

Keywords that indicate subtraction: the difference, less, fewer, decreases, subtract, remaining, etc.

Identifying Addition Operations

If a word problem asks you to find the total amount, sum, or combined quantity of a group of things, you need to use addition.

For example: There are 7 dogs and 3 cats in the animal shelter. How many animals are in the shelter in total? To solve this problem, add 7 + 3 to get 10. So there are 10 animals in the shelter altogether.

Identifying Subtraction Operations

There are several types of subtraction problems that typically demand you to compare quantities, find the difference, and subtract from whole numbers.

Compare Quantities - There are word problems that ask students to look at two different situations and compare them using the given values.

Let's look at an example of a compare quantities word problem.

Ms. Jones has 8 dogs. Mr. Smith has 2 dogs. How many more dogs does Ms. Jones have than Mr. Smith?

To solve this problem, we need to compare the two quantities and figure out how much greater one is than the other. In this case, Ms. Jones has 6 (8 - 2) more dogs than Mr. Smith.

Now let's try a word problem that asks us to find the difference between two numbers. The key to solving these problems is carefully reading and identifying what is being asked.

Mrs. Brown has 4 pounds of flour. She uses 2 and 1/4 pounds of flour to bake cookies. How much flour does she have left?

To solve this problem, we need to take the 2 and 1/4 pounds of flour away from the 4 pounds of flour Mrs. Brown started with. This leaves her with 1 and 3/4 pounds of flour left.

Finally, let's look at a word problem that asks us to subtract from a whole number.

George has 10 pieces of candy. He eats 4 pieces of candy. How many pieces of candy does George have left? To solve this problem, we need to take the 4 pieces of candy away from the 10 pieces of candy George started with. This leaves him with 6 pieces of candy.

As you can see, several different types of word problems involve subtraction. The key to solving these problems is carefully reading and identifying what is being asked. With a little practice, you'll be able to solve any subtraction word problem that comes your way!

Use of Both Addition and Subtraction

Some word problems will require you to use both addition and subtraction. For example:

On Monday, Jack had 5 pieces of candy. He gave 2 pieces to his sister. Then he found 3 more pieces on the ground. How many pieces of candy does Jack have now?

To solve this problem, start by adding 5 + 3 to get 8. But then we need to subtract 2 because Jack gave some away, so the final answer is 8 - 2 = 6. So Jack has 6 pieces of candy now.

Final Words

If you're unsure whether to use addition or subtraction in a word problem, try reading the problem aloud. This will help you identify the keywords that will tell you which operation to use.

Remember, addition is for when two things are put together, and subtraction is for when something is taken away.
