Early Patterns – Repeating Patterns You Can See
Spotting and continuing a simple repeating pattern – red, blue, red, blue… – is a foundational “pre-algebra” skill, and many maths educators consider pattern recognition one of the deepest, most transferable abilities in all of mathematics. The exact same instinct that spots “what comes next” in a row of coloured blocks resurfaces again and again throughout this whole Patterns and Sequences section – in multiplication tables, in number sequences, and eventually in algebraic formulas.
Humans have decorated pottery, textiles, and buildings with repeating patterns for tens of thousands of years, long before anyone wrote down a mathematical description of what a “pattern” actually is. That instinct to notice and continue a repeating design is genuinely ancient – this page simply gives it a name and a starting point for the more formal number patterns that follow.
AB Patterns
The simplest repeating pattern alternates between just two items, over and over: A, B, A, B, A, B…
The pattern alternates Red, Blue, over and over, so the next colour is Blue.
ABC Patterns
The pattern repeats Circle, Square, Triangle, so the missing item is Square.
Real-Life Application
- Clothing and fabric: stripes and checks are repeating patterns.
- Music: rhythms often repeat in a steady beat.
- Buildings: tiled floors and brick walls use repeating patterns.
Key Takeaways
- A repeating pattern uses a fixed unit of items over and over, such as AB or ABC.
- Finding “what comes next” means first identifying the repeating unit.
- Pattern recognition here is the seed of the number and algebraic patterns covered throughout this section.
