Maths Quiz - Year 1 Numbers - Number Patterns (Questions)

Patterns repeat in a steady order. Spot the rule, predict the next term, and build your own simple patterns with colours, shapes, and numbers.

Fascinating Fact:

Red, blue, blue, red, blue, blue. Turn it into numbers 1, 2, 2, 1, 2, 2.

In KS1 Maths, you learn to notice repeats and rules in sequences. A pattern could be colours, shapes, or numbers that follow the same order again and again.

  • Pattern: A repeat that follows a rule, such as 1, 2, 2, 1, 2, 2.
  • Rule: The instruction that makes the pattern, like “red then two blues”.
  • Term: Each item in the pattern, for example one colour or one number.
How do I find the rule in a number pattern?

Look at how the terms change. Are you adding the same amount, switching between two numbers, or repeating a short block like 1, 2, 2, 1, 2, 2?

What comes next if a pattern repeats every three terms?

Copy the same three-term block again. If the block is A, B, C, then the next terms are A, B, C in the same order.

How can I check if my answer fits the pattern?

Apply the rule to the last few terms. If your number keeps the same rule and the pattern still repeats, your answer fits.
