Patterns that help you remember it

  • The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
  • Each answer is 1 more than the one before, so you can count on in steps of 1.

Building it from tables you already know

To multiply 1 by 9, multiply by 10 and take one 1 away: 10 − 1 = 9. To multiply by 11, multiply by 10 and add one more 1: 10 + 1 = 11. Multiplying by 4 is doubling twice: 1 → 2 → 4.

There are 99 multiples of 1 below 100, and 999 below 1,000. A number is in the 1 times table exactly when it divides by 1 with no remainder.

Odd, even and the last digit

Because 1 is odd, the answers alternate between odd and even: 1 × 1 = 1 is odd, 1 × 2 = 2 is even, and so on. Multiplying by 10 always puts a zero on the end: 1 × 10 = 10, and 1 × 100 = 100. Multiplying by 5 is half of multiplying by 10: half of 10 is 5.

Using the 1 times table to divide

Every fact also works backwards: because 1 × 7 = 7, you know 7 ÷ 1 = 7 and 7 ÷ 7 = 1. Practising the table and its division facts together halves the work.

Word problems

Times tables are most useful when you can spot them in a question. Try these, then open each one to check:

  1. A box holds 1 pencils. How many pencils are in 3 boxes?
    Answer3 × 1 = 3 pencils.
  2. Tickets cost $1 each. How much do 4 tickets cost?
    Answer4 × $1 = $4.
  3. 8 chairs are set out in rows of 1. How many rows are there?
    Answer8 ÷ 1 = 8 rows.
  4. A plant grows 1 millimetres a week. How much does it grow in 6 weeks?
    Answer6 × 1 = 6 millimetres.

About this page

The table, the patterns and the practice questions are all calculated for 1 when the page is opened, so every fact on it is exact. Use the options above the worksheet to change the number of questions or the largest multiplier.

Questions

What is 1 × 12?

12.

What is half of 1 × 8?

1 × 8 = 8, and half of that is 4, which is 1 × 4. Halving one factor halves the answer.

What is 1 times 0?

0. Any number multiplied by zero is zero, because zero groups of 1 contain nothing.

What is 1 × 7 and 1 × 8?

1 × 7 = 7 and 1 × 8 = 8. These two are the facts most people find hardest, so they are worth practising on their own.

Is 15 in the 1 times table?

Yes: every whole number is in the 1 times table.

How do I learn the 1 times table quickly?

Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
