Number Patterns
Exploring patterns formed by sequences of numbers.
Core concept
Interesting relationships exist between different number patterns — for example, adding two consecutive triangular numbers always produces a square number (1+3=4, 3+6=9, 6+10=16). Patterns like these are not just curiosities; they form the basis of algebra and help students recognise structure in mathematics, which is essential for solving more complex problems in later years, including in geometry and combinatorics.
