Maths hiding in cooking: cupcake trays

Count cakes in rows and columns to see multiplication naturally.

Quick answer

Maths hiding in cooking: cupcake trays is all about using cupcake trays to learn multiplication and arrays. When you see a tray with 6 rows and 4 columns of cupcakes, you’re seeing 6 × 4 = 24 cupcakes. This helps children understand how multiplication works in real life.

Learning outcome

By the end of this page, you will understand how to use cupcake trays to learn multiplication by counting rows and columns. Success signs:
  • You can count how many cupcakes are in a tray by looking at rows and columns
  • You can work out how many cupcakes there are without counting each one
  • You can explain how multiplication helps you find the total quickly
  • You can make your own cupcake tray with different numbers of rows and columns

Why this matters

When you bake cupcakes, you're not just making something yummy – you're also using maths! Cupcake trays are a great way to see how multiplication works in real life. You can use this skill when you're helping in the kitchen, sharing food, or even when you're playing with toys. Understanding how rows and columns work helps you solve bigger maths problems later on, like area and arrays.

How it works

Think of a cupcake tray like a grid. Each cupcake sits in its own little space. If you look at the tray:
  • Count how many cupcakes are in each row (like 4 cupcakes in a row)
  • Count how many rows there are (like 6 rows)
  • Multiply them together: 6 rows × 4 cupcakes = 24 cupcakes
This is the same as adding 4 + 4 + 4 + 4 + 4 + 4 = 24. So, multiplication is just a faster way to add the same number many times.

Examples you can see

Let’s look at some real cupcake trays and count how many cupcakes are in each one. Example 1: A tray with 3 rows and 5 cupcakes in each row
  • Row 1: 5 cupcakes
  • Row 2: 5 cupcakes
  • Row 3: 5 cupcakes
  • Total: 5 + 5 + 5 = 15 cupcakes
  • Or: 3 × 5 = 15 cupcakes
Example 2: A tray with 4 rows and 6 cupcakes in each row
  • Row 1: 6 cupcakes
  • Row 2: 6 cupcakes
  • Row 3: 6 cupcakes
  • Row 4: 6 cupcakes
  • Total: 6 + 6 + 6 + 6 = 24 cupcakes
  • Or: 4 × 6 = 24 cupcakes
Example 3: A tray with 2 rows and 8 cupcakes in each row
  • Row 1: 8 cupcakes
  • Row 2: 8 cupcakes
  • Total: 8 + 8 = 16 cupcakes
  • Or: 2 × 8 = 16 cupcakes

Try it as a mini adventure

Adventure: The Cupcake Factory You are the head baker at a cupcake factory! Your job is to make sure the trays are full and count how many cupcakes are made each day. 1st time: You check a tray with 5 rows and 3 cupcakes in each row. How many cupcakes are there? 2nd time: You find a tray with 4 rows and 7 cupcakes in each row. How many cupcakes are there? 3rd time: You notice a tray with 6 rows and 4 cupcakes in each row. How many cupcakes are there? 4th time: You are making a special tray with 8 rows and 2 cupcakes in each row. How many cupcakes are there? 5th time: You finish your day and count all the trays. One tray had 3 rows and 9 cupcakes in each row. How many cupcakes are there? Answers: 1st time: 5 × 3 = 15 cupcakes 2nd time: 4 × 7 = 28 cupcakes 3rd time: 6 × 4 = 24 cupcakes 4th time: 8 × 2 = 16 cupcakes 5th time: 3 × 9 = 27 cupcakes

Common mistakes

  • Mistake: Counting the cupcakes one by one instead of using rows and columns Why it happens: It's easy to get distracted and forget the faster way Fix: Look at the rows and columns first, then multiply them
  • Mistake: Forgetting to count all the rows or columns Why it happens: Sometimes you might skip one row or column by accident Fix: Count each row or column carefully, or use your fingers to keep track
  • Mistake: Thinking 6 × 4 = 20 instead of 24 Why it happens: Mixing up the multiplication facts Fix: Practice skip counting or use a multiplication chart

Parent and carer guide

Parents and carers can help by:
  • Using cupcake trays at home to practice counting rows and columns
  • Letting children count cupcakes in different trays to see how multiplication works
  • Playing games like “How many cupcakes are there?” and asking children to explain how they counted
  • Using real trays or drawing trays on paper to make it fun
  • Encouraging children to explain their thinking, not just give answers
If a child gets stuck, try:
  • Using objects like buttons or cubes to make rows and columns
  • Writing out the addition problem first (like 4 + 4 + 4 + 4) to show how multiplication works
  • Repeating the same problem with different trays to build confidence

FAQ

What is an array in maths?

An array is a way to show multiplication using rows and columns, like a cupcake tray. Each row has the same number of items, and each column has the same number of items.

How can I use cupcake trays to learn multiplication?

You can count how many rows and columns there are, then multiply them. For example, 4 rows with 6 cupcakes each = 4 × 6 = 24 cupcakes.

Why is learning multiplication with trays helpful?

It helps you see how multiplication works in real life, makes it easier to understand, and helps you count faster without having to count one by one.

Can I use other kitchen items to practice?

Yes! You can use egg cartons, pizza boxes, or even a fruit bowl to practice counting rows and columns.

What if I forget my multiplication facts?

You can use skip counting, draw arrays, or use objects to help you. Practice makes progress!
