One Book Per Shelf 1 times table adventure

A story-led page turning one book per shelf into a junior adventure for practising the 1 times table.

Quick answer

When you put one book on each shelf, you are multiplying the number of shelves by one – and that always equals the number of shelves. So 1 x 5 = 5, 1 x 10 = 10, and 1 x 12 = 12.

Learning outcome

By the end of this page, you will know that multiplying any number by one gives you that number again – and you can use this to solve real-life problems like organizing books or sharing snacks. Success signs:
  • You can say that 1 x 7 = 7, 1 x 12 = 12, and 1 x 0 = 0
  • You can solve a problem like: "If there are 8 shelves and you put one book on each shelf, how many books do you need?"
  • You can explain that 1 x 5 = 5 because you have 5 groups of 1 book each
  • You can use your 1 times table to help with other maths problems

Why this matters

Multiplying by one is one of the easiest times tables to learn – and it helps you understand how numbers work. When you know that 1 x 5 = 5, you can use that to help with bigger problems. For example, if you are sharing 5 cookies with 1 friend, you have 5 cookies total – that’s 1 x 5 = 5. In real life, this helps you:
  • Organise your books or toys
  • Count how many items you have
  • Share snacks or games fairly
  • Understand how many groups you have when each group has one item

How it works

Multiplying by one means you have one group of something. Each group has only one item. For example:
  1. If you have 1 shelf and you put 1 book on it, you have 1 x 1 = 1 book
  2. If you have 3 shelves and you put 1 book on each shelf, you have 3 x 1 = 3 books
  3. If you have 10 shelves and you put 1 book on each shelf, you have 10 x 1 = 10 books
Think of it like this:
  • 1 x 1 = 1 book
  • 1 x 2 = 2 books
  • 1 x 3 = 3 books
  • 1 x 4 = 4 books
  • 1 x 5 = 5 books
  • 1 x 6 = 6 books
  • 1 x 7 = 7 books
  • 1 x 8 = 8 books
  • 1 x 9 = 9 books
  • 1 x 10 = 10 books
  • 1 x 11 = 11 books
  • 1 x 12 = 12 books

Examples you can see

Let’s imagine you are helping your parent or teacher set up a library shelf. Example 1: You have 5 shelves. You put one book on each shelf.
  • 1 x 5 = 5 books
  • That means you used 5 books in total.
Example 2: You have 12 shelves. You put one book on each shelf.
  • 1 x 12 = 12 books
  • That means you used 12 books in total.
Example 3: You have 0 shelves. You put one book on each shelf.
  • 1 x 0 = 0 books
  • That means you used 0 books because there are no shelves.
You can also think of it as:
  • 1 x 1 = 1 book
  • 1 x 2 = 2 books
  • 1 x 3 = 3 books
  • 1 x 4 = 4 books
  • 1 x 5 = 5 books
  • 1 x 6 = 6 books
  • 1 x 7 = 7 books
  • 1 x 8 = 8 books
  • 1 x 9 = 9 books
  • 1 x 10 = 10 books
  • 1 x 11 = 11 books
  • 1 x 12 = 12 books

Try it as a mini adventure

Adventure: The Library Book Challenge You are the librarian of a small school library. You have a special mission: to put exactly one book on each shelf. There are 8 shelves in the library. Step 1: You look at the shelves.
  • There are 8 shelves
Step 2: You place one book on each shelf.
  • Shelf 1: 1 book
  • Shelf 2: 1 book
  • Shelf 3: 1 book
  • Shelf 4: 1 book
  • Shelf 5: 1 book
  • Shelf 6: 1 book
  • Shelf 7: 1 book
  • Shelf 8: 1 book
Step 3: You count the books.
  • 1 x 8 = 8 books
Step 4: You finish the mission.
  • You placed 8 books on 8 shelves – one book per shelf
Mini challenge: Try this with 3 shelves, then 6 shelves, then 12 shelves. What do you notice?

Common mistakes

  • Mistake: Thinking that 1 x 5 = 10 instead of 5.
  • Why it happens: Confusing multiplication with addition, like 1 + 5 = 6, but forgetting that 1 x 5 means 5 groups of 1, not 1 plus 5.
  • Fix: Use visual models like drawing 5 shelves with 1 book each, or counting 5 fingers, each representing 1 book.
  • Mistake: Thinking 1 x 0 = 1 instead of 0.
  • Why it happens: Confusing "one group" with "one item" and forgetting that zero shelves means zero books.
  • Fix: Use a real-life example like “If there are no shelves, how many books do you need?” Then you can see it’s 0.
  • Mistake: Forgetting that 1 x anything = that thing.
  • Why it happens: Not seeing the pattern in the times table.
  • Fix: Practice saying “1 x 4 = 4” and “1 x 10 = 10” out loud. You can even make a chant!

Parent and carer guide

Parents and carers can help by:
  • Practising the 1 times table with their child using real objects like books, toys, or snacks
  • Using the library shelf adventure as a story to act out or draw
  • Encouraging the child to count out loud or write the facts 1 x 1 to 1 x 12
  • Looking for real-life examples around the house, like: “If you have 3 cups and put 1 spoon in each, how many spoons do you need?”
  • Not pushing too hard – this is a simple, easy table to learn
What to say:
  • “Let’s count how many books you have if you put 1 on each shelf.”
  • “What happens when you multiply any number by 1?”
  • “Can you make a drawing of 1 x 5?”
What not to worry about:
  • It’s normal to get confused at first – that’s how learning works!
  • Don’t expect perfect recall right away – repetition helps
  • Don’t compare with other tables – this one is easy!

FAQ

Why is the 1 times table easy?

Because multiplying by one always gives you the same number. It’s like saying “I have 1 group of 5 things” – that’s just 5 things!

Can I use the 1 times table to help with other math?

Yes! When you know that 1 x 5 = 5, it helps you understand that 5 x 1 = 5 too. It also helps when you are sharing or grouping things.

What happens if I multiply by zero?

If you multiply any number by zero, the answer is zero. For example, 1 x 0 = 0. It’s like saying “I have 0 shelves, so I need 0 books.”

How can I practice the 1 times table?

You can use books, toys, or snacks. Try putting one item on each shelf or plate and count how many items you used. You can also chant or sing the facts!

Is 1 x 1 the same as 1 x 1?

Yes! Both equal 1. It’s the same thing – just one group of one item.
