Subtraction word problem: Subtraction Word Problems for 3rd Grade

Subtraction Word Problems Games for Kids Online

Subtraction word problems enable kids to understand arithmetics better. Initially, they subtract within 10 before moving to advanced topics like subtracting within 100 or 1000. They also practice and learn ‘subtract to compare word problems.’ Online educational games from a best-in-class platform make the topic more accessible and convenient for kids. 

Subtraction Word Problems — A Walkthrough

Knowledge of subtraction word problems is crucial for young kids. Since subtraction is more complex than addition, kids take time to master the skill. In subtraction word problems, kids see a statement like «Aaron has 8 candies. If he gives 8 candies to Reeve, how many candies is he left with?» and need to subtract 8 from 8 to find the correct answer zero (0).

With every passing grade, the complexity of subtraction word problems increases. In the Kindergarten grade, they use the ‘difference unknown’ scenario to practice subtraction and subtract within 10. In the first grade, they solve ‘take apart’ scenario-based subtraction problems and change unknown scenarios within 10. The 2nd grade introduces them to subtraction word problems within 20.

Online educational games from platforms like Splashlearn make learning easy for kids. The following section mentions the top-3 subtraction word problems games for kids.

Three Fun Subtraction Word Problems Games To Engage Your Kids

Here are the three best interactive subtraction word problems games for kids:

1. Word Problems: Subtracting Within 10: Kids use real-world things in this interactive online game to practice subtraction. This game improves their problem-solving skills. They understand the ‘take away’ scenario and apply their knowledge to solve fundamental arithmetic problems involving subtraction.

2. Solve ‘Take Apart’ Scenarios: The more 1st grader kids practice this fun game, the better they learn subtraction. The game encourages them to solve subtraction word problems within 10 using ‘take apart’ scenarios. They see various story situations and need to solve those to guess the correct answer. The complexity level increases every time they provide a correct answer.

3. Represent ‘Take Apart’ Scenarios: This super fun game allows 2nd-grade kids to apply their prior knowledge of subtraction to real-world situations. They need to understand each story situation and represent it using equations. The fair practice of this game ensures the faster acquisition of arithmetic skills involving subtraction.

Common Hurdles Kids Face When Learning Subtraction Word Problems

One common issue kids face while learning subtraction word problems is failing to recognize the meaning of the sentences. Moreover, since subtraction is more challenging than addition, Kindergarten grade kids may face difficulty applying the equations and calculating. And too many failures may make them demoralized.  

Parents Can Play The Role of a Mentor

Young kids will need your support and guidance to perform complex calculations efficiently. Fortunately, online games provide your kids with fun activities to help them understand better. However, you may need to handhold them through the process initially. Complement the online activities with real-life examples of subtraction. Encourage and guide them as much as you can until you are sure that they can take care of themselves independently.

SplashLearn’s games can be your kids’ best friend while learning mathematics. Once they make these games a part of their daily schedule, arithmetics will entice them more than before.

Word Problems: Add on or Take Away | 2nd Grade Math

Let’s learn to solve real world problems with math like this one.

John has 10 marbles. Randy gave him 6 more marbles. How many marbles does John have now?

There are four steps to solving a word problem.

First, we gather clues.

Next, we draw a picture to figure out what we should do.

👉 We see that we need to do addition to find the whole.

Then, we write an equation, and solve it.

10 + 6 = 16

Finally, we write the answer in a word sentence.

John has 16 marbles now.

👆The problem we just solved is an Add On or Take Away problem.

In Add On or Take Away problems, we start with a number. Then, something happens that will make us either add or subtract. After this, we get a new number.

In our problem, John started with 10 marbles. 

Then something happened. Randy gave him 6 more marbles. 

👉 So, we added 10 plus 6.

Then, we got 16.

😀Tip: These are some words that can help you know what to do:

If you see the words more, increase, add, in all, and altogether, they all mean «to add».

If you see the words less, decrease, reduced, gave away, take away, and left, they all mean «to subtract».

Another Example

Let’s try another problem.

Jim has 12 stickers. He gives 5 stickers to Benny. How many stickers does Jim have left?

Step 1. Gather clues.

We see 12 stickers and 5 stickers.

We see the keywords «gives» and «left».

Step 2. Draw a picture or model.

Based on this picture, what should we do? 

We need to find the missing part.  

👉 So we subtract the part we know from the total.

We started with 12 stickers. But something happened. Jim gives away 5 stickers.

👉 We subtract 5 from 12.

Step 3. Write an equation and solve it.

12 — 5 = 7

Step 4. Write the answer in a word sentence.

Jim has 7 stickers left.

Great job! 😀

Two-Step Word Problem

Let’s solve one more word problem.

12 frogs are in the pond. 2 frogs hop away. Then 5 more frogs hop away. How many frogs are left in the pond?

Step 1. Gather clues.

Step 2. Draw a picture.

We know the whole, and some of the parts that were taken away.

Step 3. Write the equations, or number sentences.

First, we subtract the frogs that hopped away first.

12 — 2 = 10

Then, we subtract the frogs that hopped away next. 

10 — 5 = 5

There’s another way to solve this.

First, add all the frogs that hopped away.

2 + 5 = 7

Then, subtract the number of frogs that hopped away from the number of frogs we started with.

12 — 7 = 5

We see that we have the same answer.

Step 4. Write the answer in a word sentence.

5 frogs are left in the pond.

Great job!

Now, you’re ready to do some practice. 💪

so long until I tell you the next one.

H – activation of mental activity.

O, A — mood for work.

Updating knowledge.

Working with netbooks. (Junior Academy
schoolboy. The composition of the number 10).

And we will probably start with the most pleasant — this
work with netbooks. Today we complicate our
work. In the last lesson, we focused on
consisting of the number 10 in the third entrance of the numerical
at home. But not everyone was able to get to the very top
floor of the entrance and turn on the light in it. So who
did not receive a diploma in the last lesson, they
return to the composition of the number 10 in the 3rd entrance (No. 62) and
try to turn on the light and get a letter. BUT
others complicate their work and go right away
for two: on the 2nd and 3rd (No. 63) entrances. Straightaway
we agree that you are assigned to this work
only 2 minutes. Upon receipt of a diploma for a fast
and a job well done, you show it to me
and exit the junior high school academy.

#1 . Grouping items. ( Slide 3 )

— Well done! You did a wonderful job!
And we will continue to work on the numbers. Look at
examples and say which groups you can
spread out examples? (For addition and subtraction).

— Read the examples in different ways.

#2. Comparison of items. ( Slide 4 )

— Now we complicate our work. Look at
these examples and tell me how these examples are similar?

— What is the difference? (One example for addition, and
another for subtraction).

— What is the difference between addition and subtraction? (One
number increases and the other decreases).

— What conclusion can be drawn? (When adding the number
increases, and when subtracted, it decreases).

— What needs to be corrected in the tasks?

— And when solving problems, the same thing can happen
most?

— What are the parts of the problem? (From the condition and
question).

— Listen carefully to my tasks and say,
what needs to be fixed in the problem?

• The girl has 7 balloons. One balloon popped, girl
  cried.
• Kindergarten has 8 rubber balls. One ball fell and
  crashed. How many balls are left?
• Grandmother baked 8 pies. Several pies
  ate. How many pies are left?

Fizminutka.

Sports and arithmetic dictation.

— We will now solve examples with you. Only
we will not write down the numbers, but execute them
exercises. The answer you get by choosing
example, it will tell you how many times you need to execute
an exercise.

1. Forward bends 9-2.

2. Forward lunges 7-2.

3. Arm jerks up and down 10-5.

4. Side bends 6+2.

5. Pull-ups 5+1.

6. Squats 4+2.

Creation of a problem situation.

— Guys, in life you have to add up and
subtract? And in what situations?

— Yes, of course, in life we ​​always meet
tasks. For example, in a store. ( Slide 5 ).
Let’s go to the store with Ira and
Let’s try to create tasks. Ira bought ice cream
and chocolate. What question should be asked to
decided by addition?

— And what question should be asked in order for the task
resolved by subtraction?

— Look at the slide again and say
whether the condition is the same for the tasks that we
made up? Were the questions the same?

— What did the choice of action in the decision depend on
these tasks? (From the question).

— What is the topic of the lesson?

— Yes, guys, we will learn to distinguish tasks,
which are solved by adding from problems that
solved by subtraction.

( Slide 6 )

— Read two problems and say which one
must be solved by addition and which by subtraction.

— How to distinguish an addition problem from a problem with
subtraction?

— When should one add and when should one take away?

(Children put forward their hypotheses)

— I don’t know which of your opinions is correct.
How are we going to check?

(Compare tasks!)

Comparative analysis of the problem.

— Read the first problem again. Decide.
Which word helped you choose the action? (Total).

— Read the second problem. Decide. What word
helped you choose an action now? (Left).

( Slide 7 )

— Where are these words? In the condition of the task or
in the question?

— Let’s try to conclude: Say more
times which words occur in tasks on
addition and which ones for subtraction.

— Where are these words? (In questions).

+	—
Total	Remaining
For more than	Withered
Was	On… less than
Older	Took
Up, higher, further, longer	Lower, shorter, narrower

Practical work (pair work).

— And now we will work together with our neighbor.
You have a card on each desk. Someone
card number 1, the other has number 2, 3. This card has two
tasks. We agree to work with you
in the following way. Read carefully
the first task, discuss with your neighbor how
its action must be solved, find words ,
who helped you make the right choice and
circle the action sign + or — . For this
You have 3 minutes to work.

Check.

— Who has card number 1? Answer nice
mathematical language. (We solved the problem
addition, put a + sign. The word helped
“2 more”).

The memo on the slide is added at the same time.

— What other words can be added to this memo?

— Why did we bring this memo? Does she need
us?

Fastening.

No. 4 in the workbook.

— And now let’s try, using this memo,
insert the necessary action signs yourself.

— Open your workbook to page 57. Read
exercise. What should be done? For the execution of this
work is given 2 minutes.

— Evaluate your own work with
green pastes. If you have given yourself all 3
plus means you have 3 points; 2 pluses — 2 points, 1-1
score.

— What words helped you choose the right one
action?

— Where were they located: in the condition or in the question
tasks?

Total.

— What did we learn in the lesson?

— Have we completed this task?

— How to distinguish tasks? (According to).

— What actions help us choose the right one
action mark?

Reflection

— Let’s evaluate our work in the lesson. Do you have
desk of emoticons. Choose that emoji: 1. I’m all
I understand that I can do it on my own.

2. I understand everything, but I still have questions about
topic.

3. I didn’t understand much. I need to explain again.

Thank you for the lesson! You are great.

P.S.

Complete the task.

What does it mean to subtract: subtract or find the difference? . Math for moms and dads: Homework without pain

Your child will learn more than just how to add or subtract in school; he must also learn when to apply each of these operations. As a rule, children easily understand in which case something needs to be added, but subtraction in this regard is perceived worse.

Many people read examples like 37-19 as «subtract nineteen from thirty-seven»: their first impressions of working with subtraction are that something is being taken away or subtracted. We count 37 counting sticks, and now 19remove, how much is left? But after all, with the help of subtraction, you can solve many different problems, including those where nothing is “subtracted”.

I have 37 stickers and my friend has 19. How many more stickers do I have?

This problem can be solved by subtracting: 37 — 19, but nothing here is taken away from anyone — in the end I will be left with my 37 stickers, and my friend will still have 19.

Likewise, let’s say that the new game console I’m dreaming of costs £37. So far, my piggy bank has accumulated ?19. How much more do I need to save?

Children tend to solve such problems by counting up from 19 to 37, which can be written as 19+? = 37, but you could reverse the example and ask, «What is 37 — 19?»

In this case, the unmarked number line is also a powerful image and helps the child to master subtraction methods in his mind, as well as to explore its various meanings. We invite you to think a little about the following three examples: before reading further, try to find the answers and think about how you did it:

130 — 17; 130 — 118; 130 – 49.

The first example is solved by most people by «subtracting»: they remove 17 from 130, usually first subtracting 10 to get 120, and then subtracting 7 to get 113. But «subtracting» 118 from 130 is a rather cumbersome procedure. It can be done, but you most likely said to yourself: «So, 12 and 118 will be 130. » In other words, instead of «subtracting», you added to 118 and essentially looked for the difference between the two numbers. 130 — 49 sometimes prompts another «compensatory» strategy: 49close to 50, so subtract 50 from 130, get 80, and add one back (in order to compensate for the extra one we subtracted when we subtracted 50 instead of 49). All these methods can be visualized on an unmarked number line.

Many teachers today recommend that children accompany the score with such short drawings or notes, because, according to psychologists, children gradually begin to work with some imaginary version of the number line and in the future they can add and subtract without any notes .

Quick tip

When working with children, try to use a variety of words when reading subtraction problems. So, when there is an example of 10 — 7, you can say: “Subtract seven from ten”, “Ten minus seven”, “Subtract seven from ten”, “What is the difference between ten and seven”, “How much is ten more than seven?” «How much less is seven than ten?»

Check yourself

Here’s a real-life problem. It is possible that, when solving it, you will apply different methods, including subtraction and addition.

Rachel buys a pair of sandals for £13.75 and a pair of trainers for £32.40.

1. How much change will she get with ?50?

2. How much more expensive are sneakers than sandals?

Difference square game

Draw a very large square on a piece of paper. Ask the child to choose some interesting numbers and put them in the four corners of the square. Mark the middle of each side of the square; together with the child, determine the difference between the numbers in adjacent corners and write down the resulting number near the mark in the middle of the corresponding side. (In our case, the difference between the numbers in the top corners is 8, and the numbers on the left side differ by 11. You can fill in the rest yourself …)

Now connect the marked midpoints of the sides with line segments to get a smaller square at an angle to the first one.
