Big Ideas
Mathematics is sometimes referred to as the "science of patterns." Exploring patterns and then translating and representing these patterns into words, symbols, expressions, equations and graphs help Grade 9 students better understand linear functions. Connecting functions to prior learning and to real-life situations facilitates student learning. There are several important
Big Ideas that are addressed in this outcome:
- Algebra is a way to represent and explain mathematical relationships and is used to describe and analyze change (Small 2009, p.7).
- Equations are used to express relationships between two quantities (Van de Walle 2001, p. 384).
- The equal sign means that the quantity on the left-hand side of the equation is the same as the quantity on the right-hand side.
- 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).
