Classroom Tables times-table story

A playful story page showing how classroom tables can teach arrays in real life.

Quick answer

Classroom tables can teach us about multiplication through arrays – the rows and columns of chairs around each table show us how multiplication works in real life.

Learning outcome

By the end of this page, you will understand how to use classroom tables to show multiplication as arrays – with rows and columns of chairs that help you see how groups of items can be counted in different ways. Success signs:
  • You can count the chairs around a table and show how they make rows and columns.
  • You can make a multiplication sentence from the number of rows and columns.
  • You can use a table to show how 3 x 4 = 12 in a real-life way.
  • You can explain how arrays help you understand multiplication.

Why this matters

Multiplication is not just about numbers on a page – it’s about groups and arrays around us every day. When you sit at a classroom table, you are part of a multiplication array. Understanding this helps you see how maths works in real life, not just in books. It helps you solve problems faster, and it makes learning multiplication more fun.

How it works

Think of a classroom table as a grid. If there are 3 chairs on one side and 4 chairs on the other, you can see how many chairs there are in total by multiplying 3 × 4 = 12. This is an array – a way of arranging things in rows and columns. Let’s look at how this works step by step:
  1. Count the number of chairs along one side (that's the number of rows).
  2. Count the number of chairs along the other side (that's the number of columns).
  3. Multiply the rows by the columns to find the total number of chairs.
  4. Draw or imagine the array to help you see it.

Examples you can see

Let’s imagine a classroom table with 4 chairs on each side. That means:
  • There are 4 chairs in each row.
  • There are 4 rows of chairs.
  • So, 4 rows × 4 columns = 16 chairs in total.
This is the same as saying:
  • 4 + 4 + 4 + 4 = 16 (repeated addition)
  • 4 × 4 = 16 (multiplication)
Ages 4-6: Try drawing a 3 × 3 array on paper. Draw 3 rows and 3 columns of dots or stickers. Count them all together. You can do this with any small number of rows and columns. Ages 7-9: Use your classroom table to count how many chairs there are. If you have 5 rows and 3 columns, you can write 5 × 3 = 15. Ages 10-12: Try to find arrays in your house. A box of eggs is a 3 × 4 array. A bookshelf with 6 rows of 4 books is 6 × 4 = 24 books.

Try it as a mini adventure

Adventure: The Classroom Array Hunt You are a detective in a classroom. Your job is to find the arrays on each table and write down the multiplication sentence for each one. 1st time: Look at your table. How many chairs are on one side? How many are on the other side? 2nd time: Write the multiplication sentence (e.g. 3 × 4 = 12). 3rd time: Draw the array to show your work. 4th time: Find another table and repeat the process. 5th time: See if you can find a table with 6 × 5 = 30 chairs. Can you find the biggest array in the classroom?

Common mistakes

  • Mistake: Thinking that 4 rows and 3 columns make 4 + 3 = 7 chairs. Why it happens: Confusing addition with multiplication. Fix: Remember that when you have rows and columns, you multiply them. 4 × 3 = 12.
  • Mistake: Counting the same chair twice. Why it happens: Not keeping track of what you’ve counted. Fix: Count carefully and use a finger or pencil to mark each chair as you count it.
  • Mistake: Mixing up rows and columns. Why it happens: Not knowing which direction is the row and which is the column. Fix: Ask a friend or teacher to help you decide which way is the row and which is the column.

Parent and carer guide

Parents and carers can help by:
  • Playing the classroom array game with their child at home using a table or a tray.
  • Encouraging children to count the chairs around a table and write the multiplication sentence.
  • Using real-life examples like a box of eggs (3 × 4 = 12) or a grid of stickers (5 × 5 = 25).
  • Practising skip counting along the rows or columns to help with multiplication.
  • Noticing when children are struggling to count or understand rows and columns, and offering gentle support.

Practice questions

  1. If a table has 3 rows and 4 columns of chairs, how many chairs are there in total?
  2. How many chairs are there in a table with 5 rows and 2 columns?
  3. Draw an array for 4 × 3 = 12 and count the total.
  4. What is 6 × 4?
  5. Find a table at home with 2 rows and 5 columns. How many chairs are there?
Answers:
  1. 12 chairs
  2. 10 chairs
  3. Draw 4 rows and 3 columns of dots or stickers and count them (12 total)
  4. 24
  5. 10 chairs

FAQ

What is an array?

An array is a way of arranging objects in rows and columns. For example, 3 rows of 4 chairs make an array of 12 chairs.

Why are arrays important in learning multiplication?

Arrays help children understand that multiplication is about equal groups in rows and columns. It makes the concept more visual and easier to grasp.

Can I use arrays for any multiplication?

Yes! You can make an array for any multiplication sentence, like 2 × 6 or 7 × 3.

How can I make arrays at home?

You can use items like coins, blocks, or stickers. Arrange them in rows and columns to show multiplication.

What if I don’t have a classroom table?

You can still make arrays with anything you can arrange in rows and columns – like a box of chocolates, a grid of tiles, or a tray of food.
