Why this matters
Time-travel maths is not just for space explorers! When you go to the shop, plan a birthday party, or save up for a toy, you're using time and money skills. Whether you're buying a train ticket, checking how long you've been waiting, or counting coins in your pocket, time and money are all around you. Learning to use clocks, calendars, and money together helps you become a smart shopper, a good planner, and a confident problem solver!
How it works
Time-travel maths uses three main ideas:
- Clocks tell you the time to know when to buy things
- Calendars help you plan your spending over days or weeks
- Money helps you count how much you have or need
When you put these together, you can plan your budget, know when to save, and make smart choices.
Examples you can see
Imagine you're planning a time-travel adventure to ancient Egypt. You need to buy a ticket for 50p, and you have 3 coins: 20p, 10p, and 20p. How much do you have? Let's count:
| Coins | Value |
|---|---|
| 20p | 20p |
| 10p | 10p |
| 20p | 20p |
| Total | 50p |
You have exactly enough to buy the ticket!
Now, let's say you're planning to save up for a special time-travel toy. You have a calendar and see that your birthday is in 3 weeks. If you save 50p each week, how much will you have?
| Week | Saved |
|---|---|
| Week 1 | 50p |
| Week 2 | 50p |
| Week 3 | 50p |
| Total | £1.50 |
By your birthday, you'll have £1.50 to spend on your toy!
Try it as a mini adventure
Imagine you're on a time-travel quest to medieval times. You need to buy food and a map. Here's your challenge:
- You have 3 coins: 50p, 20p, and 10p
- Food costs 60p
- Map costs 40p
- How much money do you have?
- Can you buy both items?
- If not, what can you buy?
First, count your money:
- 50p + 20p + 10p = 80p
Next, add up the items:
- Food (60p) + Map (40p) = 100p
Oh no! You don't have enough money to buy both. You can buy:
- One item for 80p (either food or map)
- Or save up more money
Common mistakes
- Mistake: Forgetting to count all the coins when adding up money
- Why it happens: Getting excited about the adventure and rushing to count
- Fix: Count each coin slowly and write down the total
- Mistake: Thinking that 100p equals £1, but mixing up pence and pounds
- Why it happens: Not knowing the value of each coin
- Fix: Practice with real coins or play with a piggy bank to learn values
- Mistake: Not checking if you have enough money before buying
- Why it happens: Wanting to buy everything at once
- Fix: Add up the prices first, then check your money

FAQ
Why do we need to know time and money for time travel?
Because time travel means you have to plan ahead, and planning needs both time and money. You need to know when to travel, how long it takes, and how much it costs.
How can I practice time and money skills at home?
You can play shop with toys, use a calendar to track your savings, or count coins while you're out shopping. The more you practice, the better you get!
What if I don't have enough money?
That's okay! You can save more, choose cheaper items, or ask a grown-up for help. Budgeting means making smart choices.
Can I use time and money skills in other games?
Yes! In games like Minecraft or Roblox, you can use time to plan building projects and money to buy items. It's like real life, but in a fun way!
How do I know if I have enough money?
Add up the prices of what you want to buy, then compare it to how much money you have. If your money is more or equal to the total, you can buy it!
