Patterns

A pattern is a series that is repeated more than one time. From the shape of a flower to the numbers on a clock, everywhere you look you will be able to find some sort of pattern, whether man made or natural. However, patterns can be much more than a set of shapes.

Patterns are an essential and central part of maths. Think back to Primary 1 and 2 when you first started to learn to recognise and count numbers within 20. You were taught this through patterns and number stories.

For example, the story of 3 is:

3+0, 2+1, 1+2 and 0+3.

Patterns are also a great tool in helping you develop the key thinking skill of mathematical reasoning. This sounds like a bit of a mouthful, but it basically means your ability to think logically about a problem to work out the best steps and strategies to use to help solve it.

For example, when you were learning your 9 times tables, you may have noticed that the digits of any multiple of nine will add up to nine (or a multiple of nine), which is a really handy way of checking your answers:

9 x 3 = 27 (2 + 7 = 9).

Using patterns to help solve maths problems

Identifying the rule for a repeated number pattern can help you solve sequences where numbers are missing, for example:

7, 14, 21, __, 35

By finding the relationship between neighbouring sets of numbers (adding 7 or multiples of 7), you can calculate the missing number, in this case 28.

This pattern will also allow you to confidently predict numbers as the sequence grows or shrinks. For example: What would the eleventh number be in this sequence? As we already have the first 5 numbers, and because we know the pattern is following the 7 times tables, the eleventh number can be calculated using the sum 7 x 11 = 77.
