  1. Patterns

  2. 2, 4, 6, 8, … 1, 3, 5, 7, 9, … • Geometrical • Numerical

  3. Where can you find patterns? • music • investments • sleep habits • nature

  4. From pictures or physical models we can sometimes find both numerical and geometrical patterns.

  5. Understanding a pattern can help us: • extend the pattern • create new patterns

  6. MODELS Numerical Mathematicians … • look for patterns • find patterns in physical or pictorial models • look for ways to create different models for patterns • use mathematical models to solve problems Algebraic Graphical

  7. Number Patterns Term Number Term Expression 2 2 + 2 2 + 2 + 2 2 + 2 + 2 + 2 2 1(2) 1 2 3 4 n? 4 2(2) 6 3(2) 8 4(2) __(2) n
