Big Ideas

  • Patterns represent identified regularities. Types of patterns include complex repeating patterns, increasing and decreasing patterns, and recursive patterns (Small 2009, p.3).
  • A variable is a symbol that can stand for any one of a set of numbers or other objects and can be represented by boxes or letters (Van de Walle and Lovin 2006, p. 274).
  • Patterns are key factors in understanding mathematical concepts. The ability to create, recognize and extend patterns is essential for making generalizations, seeing relationships and understanding the order and logic of mathematics (Burns 2000, p. 112).
  • Patterns can be recognized, extended and generalized into symbols, words, diagrams, number lines, charts and graphs (Van de Walle and Lovin 2006, p. 265).
