Year 1 Numbers - Number Patterns
Patterns are all around us. Can you see the patterns in numbers?

Year 1 Numbers - Number Patterns

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.

Question 1
What is the next number in this sequence:
80, 70, 60, 50, 40
41
30
39
10
The numbers are going down in tens
Question 2
What is the next number in this sequence:
99, 98, 97, 96, 95
94
