Examples you can see

Let's look at some real examples to understand these words:

Percent

Imagine you have a pizza cut into 100 pieces. If you eat 25 pieces, that's 25 percent of the pizza. This is the same as saying "25 out of 100".

Discount

At the toy shop, a toy costs £10. If there's a 20% discount, you save £2. So you only pay £8.

Increase

Your pet goldfish was 5cm long. After a week, it grew to 7cm. That's an increase of 2cm.

Decrease

You had 12 sweets. You ate 3 sweets. Now you have 9 sweets. That's a decrease of 3 sweets.

Try it as a mini adventure

Adventure: The Shopping Trip

You're going to the shop with £20 to buy some toys. Here's your mission:

1. Find a toy that costs £12
2. There's a 10% discount on it
3. How much will you save?
4. How much will you pay?
5. How many toys can you buy with £20 if each costs £5?
6. What happens if the price increases by 25%?

Let's solve this step by step:

1. Toy costs £12
2. 10% of £12 = £1.20
3. You save £1.20
4. You pay £10.80
5. With £20, you can buy 4 toys at £5 each
6. If price increases by 25%, new price = £5 + £1.25 = £6.25

Common mistakes

  Fix: Remember "cent" means 100, like a century has 100 years
• Mistake: Mixing up increase and decrease
  Why it happens: Not paying attention to whether something gets bigger or smaller
  Fix: Ask yourself "is it going up or down?"
• Mistake: Thinking discount means you pay more
  Why it happens: Confusing the word "discount" with "cost"
  Fix: Remember discount means "less money to pay"
