Why this matters

When you cook with others, maths helps make sure everyone is safe and happy. If you're making a birthday cake, you don't want the cake to burn or the dinner to be late. Maths helps you plan your time so that everything happens in the right order and at the right time. This is especially important when you're cooking with others or when you're trying to make sure your family eats together. Whether you're helping with dinner or making a special treat, planning your time with maths makes everything easier. It's like being a chef who knows exactly when to start each step so that everything comes out perfect.

How it works

Here's how to plan a cooking schedule using maths:
  1. Look at the recipe and write down all the steps
  2. Estimate how long each step takes (like 5 minutes for chopping or 10 minutes for cooking)
  3. Put the steps in order so they make sense
  4. Plan when to start each step so everything is ready at the same time
This is like solving a puzzle where each piece is a cooking step and you need to fit them together in the right way and at the right time.

Examples you can see

Let's imagine you're making a simple sandwich and a fruit salad for a picnic. Step 1: List all the steps
  • Get the ingredients
  • Wash the fruit
  • Chop the fruit
  • Make the sandwich
  • Put everything in a picnic basket
Step 2: Estimate how long each step takes
Step Time needed
Get ingredients 2 minutes
Wash fruit 3 minutes
Chop fruit 4 minutes
Make sandwich 5 minutes
Put in basket 2 minutes
Step 3: Put steps in the right order
  • Get ingredients
  • Wash fruit
  • Chop fruit
  • Make sandwich
  • Put in basket
Step 4: Plan when to start each step If you want to start at 10:00, you can start:
  • 10:00 - Get ingredients
  • 10:02 - Wash fruit
  • 10:05 - Chop fruit
  • 10:09 - Make sandwich
  • 10:14 - Put in basket
Real-world example: Making pancakes Let's say you're making pancakes for breakfast.
Step Time needed
Get ingredients 2 minutes
Mix batter 3 minutes
Heat pan 2 minutes
Cook pancakes 10 minutes
Serve 2 minutes
If you start at 8:00:
  • 8:00 - Get ingredients
  • 8:02 - Mix batter
  • 8:05 - Heat pan
  • 8:07 - Cook pancakes
  • 8:17 - Serve
You can see that cooking pancakes takes a long time, so you need to start early. You also notice that you can mix the batter while the pan heats up.

Common mistakes

  • Mistake: Starting all steps at the same time. Why it happens: Thinking that everything can be done at once. Fix: Remember that some steps need to happen one after another, like cooking pancakes before serving them.
  • Mistake: Not planning ahead and starting steps too late. Why it happens: Not knowing how long each step takes. Fix: Practice timing yourself with a timer or watch, or ask a grown-up to help you estimate.
  • Mistake: Forgetting to include breaks or rest times. Why it happens: Not thinking about how long you really need to rest or breathe. Fix: Add a few extra minutes for things like washing hands or taking a short break.

Parent and carer guide

Helping your child with kitchen maths is a great way to show how useful maths is in real life. Here's how to support them in 5-10 minutes:
  • Ask questions: "How long do you think it will take to make your sandwich?" or "What's the best order to do these steps?"
  • Use a timer: Let your child set a timer for each step so they can see how long things take.
  • Count together: Count how many minutes each step takes, or use a stopwatch to see how fast they can complete a task.
  • Be patient: It's okay if they make mistakes. Learning to plan time is a skill that takes practice.
  • Keep it fun: Make it a game or challenge. "Let's see who can plan the fastest lunch!"
What not to worry about:
  • Your child doesn't need to be perfect at timing
  • They don't need to do everything exactly right
  • It's okay to change the plan if something takes longer than expected
