Financial Literacy:Although Financial Literacy is not a strand within the Math Curriculm, it must be integrated into teaching math K-12. So, when you explore decimals, money, algebraic growth patterns, data management, and basic operations try to integrate some of the resources already developed for use in the elementary classroom (e.g, lesson plans, interactive games, on-line stock market investment games, etc.)
