Farm maths quest: money

A story-led junior maths adventure using crops, fences and animal groups to budget coins, tickets and shop items.

Quick answer

You can use maths to count, add, and subtract money when farming, buying seeds, feeding animals, and selling crops.

Learning outcome

By the end of this page, you will be able to use money to buy and sell farm items, count coins, and solve simple money problems using addition and subtraction. Success signs:
  • You can count different coins and notes to find the total amount
  • You can add money amounts together to find how much you have
  • You can subtract money amounts to find how much is left
  • You can solve simple farm-related money problems

Why this matters

Money maths helps you understand how to pay for things, save your pocket money, and make smart choices. In farming, money helps you buy seeds, feed animals, and sell your crops. When you learn about money now, you'll be ready to manage your own money when you're older.

How it works

Money maths uses the same ideas as counting and adding, but with coins and notes. You can:
  1. Count each coin or note
  2. Add them together to find your total
  3. Subtract to see how much is left after spending

Examples you can see

Let's imagine you're helping on a farm. You have 3 coins: 50p, 20p, and 10p. How much money do you have?
  • 50p + 20p + 10p = 80p
You buy a packet of seeds for 30p. How much money do you have left?
  • 80p - 30p = 50p
Here's another example: You have 2 £1 coins and 3 50p coins. How much money do you have?
  • 2 × £1 = £2
  • 3 × 50p = 150p = £1.50
  • £2 + £1.50 = £3.50

Try it as a mini adventure

Farm Shop Challenge You're the shopkeeper at the farm shop. You have these coins:
  • 4 x 50p coins
  • 3 x 20p coins
  • 2 x 10p coins
  • 5 x 5p coins
How much money do you have in total?
  • 4 × 50p = 200p = £2
  • 3 × 20p = 60p
  • 2 × 10p = 20p
  • 5 × 5p = 25p
  • £2 + 60p + 20p + 25p = £3.05
Now, a farmer wants to buy 3 bags of animal feed that cost 75p each. How much will that cost?
  • 3 × 75p = 225p = £2.25
How much money will you have left after selling the feed?
  • £3.05 - £2.25 = 80p
Mini challenge: Can you find 3 different ways to make £1 using coins?

Common mistakes

  • Mistake: Thinking 50p + 50p = £1.00 but getting confused about pence
    Why it happens: Mixing up pence and pounds
    Fix: Remember 100p = £1, so 50p + 50p = 100p = £1
  • Mistake: Forgetting to count all the coins
    Why it happens: Getting distracted or rushing
    Fix: Count each coin one by one and write it down
  • Mistake: Adding 20p + 30p = 50p instead of 50p
    Why it happens: Adding the numbers but not thinking about units
    Fix: Always remember to add pence with pence and pounds with pounds

Parent and carer guide

To help your child with farm money maths:
  • Use real coins at home to practice counting
  • Play a shopping game where you buy items and calculate the cost
  • Ask your child to help you budget for a family trip
  • Encourage them to think about how much things cost in the real world
  • Use farm-themed examples like buying seeds or feeding animals
What to watch for:
  • Are they mixing up pence and pounds?
  • Do they count coins carefully?
  • Can they add and subtract money amounts?
How to support without pressure:
  • Make it fun with games and stories
  • Don't worry if they make mistakes - that's how we learn
  • Use everyday situations like shopping to practice
  • Give praise for effort, not just correct answers

Practice questions

  1. You have 3 coins: 50p, 20p, and 10p. How much money do you have?
  2. You buy a packet of seeds for 30p. How much money do you have left if you started with 80p?
  3. You have 2 £1 coins and 3 50p coins. How much money do you have?
  4. You buy 2 bags of animal feed that cost 75p each. How much do they cost?
  5. You have 4 coins: 50p, 20p, 10p, and 5p. How much money do you have?
Answers:
  1. 50p + 20p + 10p = 80p
  2. 80p - 30p = 50p
  3. 2 × £1 = £2; 3 × 50p = 150p = £1.50; £2 + £1.50 = £3.50
  4. 2 × 75p = 150p = £1.50
  5. 50p + 20p + 10p + 5p = 85p
