Class VI: Patterns in Mathematics
Explore triangle numbers, square numbers, growing patterns, difference patterns, visual dot arrangements, and rule-making.
Fact Sheet: What is a Pattern?
A pattern is a repeated or growing arrangement that follows a rule. In mathematics, we can find patterns in numbers, shapes, dots, tiles, and real-life designs.
Triangle Numbers: 1, 3, 6, 10, 15, ...
1361015?
Differences are +2, +3, +4, +5, so the next difference is +6. Therefore, 15 + 6 = 21.
A good pattern answer gives both the next value and the reason.
