Word problems about money

Word problems with money are first introduced in the Maths Curriculum in Year 2. At this stage, children learn to recognise the different coins and the symbols for pounds and pence; find different combinations of coins and begin to solve simple addition and subtraction word problems.

As pupils progress through primary, they continue to encounter money and word problems involving money, right through to upper Key Stage 2. By Year 6 money is no longer specifically identified in the curriculum. However, pupils continue to be exposed to money word problems, through a range of mathematical concepts and word problems including: addition and subtraction word problems, division word problems, multiplication word problems decimals, fractions, percentages, ratio and algebra.

When children are first introduced to money problems, it is important for them to physically have the money to hold and manipulate, to help solve the problems. As students progress through the school, there is less of a need to have the money physically in their hands. Once they have built confidence in using written calculation methods, they are able to solve more complex problems involving money.

Money word problems in the national curriculum

Money word problems in Year 2

In Year 2, pupils are introduced to the different coins; learn the symbols for pounds and pence and combine amounts to make a particular value. They work on simple problems in a practical context involving addition word problems, and subtraction word problems of money of the same unit, including giving change.

Money word problems in Year 3

Pupils in Year 3 continue to build on their understanding of money and its use in a practical context. They progress from adding and subtracting money of the same unit, to working with both pounds and pence; adding and subtracting amounts and giving change. Pupils in Year 3 start to solve simple 2-step calculations, by finding totals and working out how much change would be given.

Money word problems in Year 4

In Year 4, the curriculum no longer mentions money under measures, but pupils continue to work with money through fractions and decimals. At this stage, pupils are expected to solve simple measures and money problems involving fractions and decimals to two decimal places.

Money word problems in Year 5

Pupils in Year 5 are becoming more confident with the formal written methods for the four operations and are exposed to money word problems involving all four. They also continue to build on the knowledge of fractions and decimals and are first introduced to percentages through a range of word problems.

Money word problems in Year 6

By Year 6, money is no longer explicitly mentioned in the curriculum, however pupils are exposed to word problems across a range of concepts, including: the four operations, fractions, decimals and percentage word problems, ratio word problems and algebra.

Why are word problems important for children’s understanding of money

Word problems are essential to children’s understanding of money, because they enable students to use money in a range of contexts they will be using in real-life. Confidence with money is a key life skill and it is important children have plenty of exposure to using it in a wide range of contexts. Money problems give children the opportunity to utilise the skills they have learnt in the maths lessons and put them into context, in a situation they understand and can relate to.

How to teach money word problem solving in primary school

Pupils need to be taught the skills needed to solve word problems. It is essential they understand the importance of reading questions carefully, making sure they fully understand what is being asked. They then need to identify which calculation is required and whether there are any concrete resources or pictorial representations they can use to help them, alongside the coins, such as place value counters and bar models.

Here is an example:

An adult’s ticket to the water park costs £15.50, whilst a children’s ticket cost £9.50.

How much would it cost for 2 adults and 2 children to visit the water park and how much change would they get from £100?

How to solve:

What do you already know?

  • We know that an adult ticket costs £15.50 and a child ticket costs £9.50.
  • To calculate the cost of both adults, we are going to need to multiply the £15.50 by 2, or add £15.50 and £15.50.
  • We will also need to do the same with the child’s ticket, costing £9.50.
  • Once we have calculated the total cost of both adults and both children, we’ll need to add these answers together, to establish the total cost for the whole family.
  • To calculate the amount of money from £100, we will need to subtract the total cost for the family from £100.

How can this be represented pictorially?

money bar models

  • We can draw bar models to represent the cost of the adult tickets, child tickets and the total for the family.
  • We can then use the answer from the third bar model to represent finding how much change from £100.
  • We can see from these bar models that there would be £50 left once the family had paid to enter the waterpark.

Money word problems for year 2

Money word problems in Year 2 require students to recognise coins and use the symbols for pounds and pence. Children solve real world problems –  finding totals and calculating change when working with the same unit (pounds or pence). 

Question 1

Mason buys a pen for 14p and a rubber for 8p. How much does he spend altogether?

Answer: 22p

14 + 8 = 22

Question 2

Maisie gets 20p from the tooth fairy. She already had 16p.

How much does she have now?

Answer: 36p

20 + 16 = 36

Question 3

Maisie has 3 coins.

She has 16p in total.

Which 3 coins must she have?

Answer: 10p, 5p and 1p

10 + 5 + 1 = 16

Question 4

Maryam spends 28p on a bag of sweets.

She gets 12p change.

How much did she pay for the bag of sweets?

Answer: 40p

28 + 12 = 40p

Question 5

Hamza has two 20p coins.

He buys a chocolate bar for 30p.

How much change does he get?

Answer: 10p change

20 + 20 = 40

40 – 30 = 10

Money word problems for year 3

Word problems for year 3 build upon the knowledge from year 2,  solving word problems involving both pounds and pence together and calculating change. At this stage, children should be using decimal notation for amounts of money and using both formal and informal methods to add and subtract money amounts in pounds and pence.

Question 1

(Pictures of 1p, 5p, 10p, 20p, 50p and £1 coins here)

Jamie has the coins above in his wallet. If he takes out 3 coins, what is the highest amount he could take out of his wallet?

Answer: £1.70

£1 + 50p + 20p

Question 2

Noah buys 2 chocolate bars for £1.35 each and a packet of crisps for 45p.

How much does he spend altogether?

Answer: £3.15

1.35 x 2 = 2.70

2.70 + 45 = 315

Question 3

Tickets for the school fair are £1.50 for children and £2.50 for adults.

How much will it cost for family of 2 adults and 2 children to go to the fair?

1.50 x 2 = 3

2.50 x 2 = 5

3 + 5 = 8

Question 4

Jackson buys 4 apples for 30p each and 2 bananas for 25p each.

How much does he spend altogether?

Answer: £1.70

30 x 4 = 120

25 x 2 = 50

120 + 50 = 170

Question 5

Amaya had £10 to spend at a carboot sale.

She bought 2 books for £1.20 each and a pack of pens for £1.50,

How much money did she have left at the end?

Answer: £6.10

Children should be able to solve each part mentally, by adding the pounds and then the pence.

1.20 +1.20 = 2.40

2.40 + 1.50 = 3.90

To work out how much change Amaya would get, children can count up from £3.90 to £10.00. They will find this easier than subtracting £3.90 from £10.00.

10.00 – 3.90 = 6.10

Money word problems for year 4

With word problems for year 4, pupils need to be able to order amounts of money, using rounding to estimate and calculate using the four operations. They also encounter money maths problems through other concepts, such as fractions.

First, we will look at a money word problem involving calculating Simple Interest. Simple Interest word problems are based on the formula for Simple Interest and the formula for Amount. Then, we will look at a money word problem that involves coins and dollar bills.

The following diagram gives the Simple Interest Formula. Scroll down the page for more examples and solutions on how to use the Simple Interest Formula to solve simple interest word problems.

Simple Interest Formula

Simple Interest Word Problems

Formula for Simple Interest

i = prt

i represents the interest earned.
p represents the principal which is the number of dollars invested.
r represents the interest rate per year.
t represents the time the money is invested which is generally stated in years or fractions of a year.

Formula for Amount

A = p + i

A represents what your investment is worth if you consider the total amount of the original investment (p) and the interest earned (i)

Example:

James needs interest income of $5,000. How much money must he invest for one year at 7%? (Give your answer to the nearest dollar)

Solution:

5,000 = p(0.07)(1)

p = 71,428.57

Simple Interest Word Problems

Example:
Pam invested $5000. She earned 14% on part of her investment and 6% on the rest. If she earned a total of $396 in interest for the year, how much did she invest at each rate?
Note that this problem requires a chart to organize the information. The chart is based on the interest formula, which states that the amount invested times the rate of interest = interest earned. The chart is then used to set up the equation.

Welcome to this Mometrix lesson on word problems with money. Usually word problems with money will deal with purchasing something, taxing something, or maybe deducting something from a total price. When reading a word problem, it could get overwhelming, seeing as you’re expected to solve a paragraph of text; surely that’s not math, right? If this is your thought process, well, I’ve got some helpful tips for you! For starters, word problems are not all that scary and actually quite easy to maneuver once you know how, and second, yes, math problems can exist in a block of text! Today, we’re going to break down the scary assumptions that come with solving money word problems and learn how to solve them without hesitation!

The best way to learn something is to try it for yourself, so let’s start by looking at a problem I’ve created:

You and your friends want to order a large pizza for $14.99. You have a budget of: $20. Considering the tax of 4% and the tip at 30%, will you have enough money to buy the large pizza?

When starting a word problem, a good rule of thumb is to identify information that is necessary and information that is unnecessary in the problem.

Your budget of $20 is unnecessary information starting out, however it will become important once we solve the problem. At this point, we really only need to focus on the price of the pizza and finding out what the tax is. Then we can move on from there.

First, we need to determine how much our tax will add onto the bill. To do this, we need to multiply 14.99 with 4%, or .04. (14.99)(.04)=.5996

Next, we need to add .5996, our tax, to 14.99, our total.

To keep our number most accurate, we won’t round to the nearest cent until we have reached our final number.

So, we have .5996+14.99=15.5896

Now that we know the sum of the original total and our tax, we need to factor in a 30% tip.

We need to multiply 15.5896 with 30%, or .30. (15.5896)(.30)=4.67688

Lastly, we need to add 4.67688 with 15.5896 to reach our total number 15.5896+4.67688=20.266. After rounding up, we reach 20.27.

The total for your order would be $20.27. You would be $.27 short of being able to order a pizza for you and your friends. I’d say it’s time to start checking the couches for spare change!

When we break down word problems into manageable steps, they seem a lot less daunting, right? Next time you’re given a word problem with money to solve, be sure to start with what is known, what is necessary, and what is unnecessary information in the word problem. Identifying these things will help to clear up your understanding of what is being asked in the problem. After identifying the necessary information needed to solve the problem, perform the operations outlined in the question to reach your total(s) and compare your answers.

Question #2:

 
Determine the piece of information that is irrelevant to solving the problem.

Jane is purchasing dog food at her local pet store. Jane notices that the store is having a 20% off sale on dog toys. Jane sees that Brand A of dog food costs $45 for a 20 pound bag, and Brand B of dog food costs $49 for a 22 pound bag. Which brand of dog food is less expensive when considering dollars per pound?

Brand A costs $45 per pound

Brand B costs $49 per pound

The store is having a 20% off sale on dog toys

All of the information provided is crucial for solving the problem.

Show Answer

Answer:

The price per pound for Brand A and Brand B is crucial for solving the problem. This information is what will allow us to determine which brand is the better deal. The fact that the store is having a 20% off sale on dog toys is irrelevant to the problem.

Question #3:

 
Dianne and Gary order sushi from their favorite restaurant for Gary’s birthday. The bill is $45.50 before the tip. Dianne offers to pay for the entire meal plus tip. She only brought $55 in cash, and she plans on leaving a 20% tip. Gary says that he has $44 in his wallet and he is willing to help with the bill. Does Dianne have enough to pay for the whole meal plus tip, or will Gary need to contribute to the bill?

Yes, Dianne will have enough to pay for the entire bill plus tip.

No, Dianne will not have enough to pay for the entire bill plus tip. Gary will need to contribute in order to cover the bill.

Show Answer

Answer:

Information that is irrelevant: Gary says that he has $44 in his wallet and he is willing to help with the bill. (This piece of information can be ignored because it is not crucial for solving the problem).

The tip can be calculated by multiplying $45.40 by 20% or 0.2. $45.50 × 0.2 = $9.10 tip. This can be added to the bill in order to determine the total cost of the meal.

$9.10 + $45.50 = $54.60

Dianne has $55, so she has enough to pay for the entire meal plus tip.

Question #4:

 
Eugene spends $24 on toy cars. He purchased 6 cars. His friend Julian spends $28 on toy cars. If each car is the same price, how much did Eugene spend on each car?

$3 per car

$4 per car

$5 per car

$6 per car

Show Answer

Answer:

Information that is irrelevant: His friend Julian spends $28 on toy cars.

The important information in the text is that Eugene spends $24 on 6 cars. If each car is the same price, then we can divide $24 by 6 in order to determine the price per car. $24 divided by 6 is 4, so $4 per car.

Question #5:

 
Jason has a part-time lawn mowing job in the summers. This week Jason mows four lawns on Monday, five lawns on Tuesday, and three lawns on Thursday. He earns $35 per lawn, and he always saves 20% of the money he makes per lawn into his savings account. On Friday Jason spends $12 on ice cream with his friends. How much money did Jason place in his savings account this week?

$84 is placed in his savings account.

$420 is placed in his savings account.

$100 is placed in his savings account.

$35 is placed in his savings account.

Show Answer

Answer:

Information that is irrelevant: On Friday Jason spends $12 on ice cream with his friends.

Jason earns $35 per lawn, and he mows 12 lawns this week. $35 times 12 is 420, so he earns $420 this week. 20% of this will be placed in his savings account. 0.2 times $420 is 84, so $84 is placed in his savings account this week.
