Everyday Mathematics is the research-based math curriculum model for all students K-5, and for grade 6 in 2008-2009. 

Everyday Mathematics covers a broad range of mathematics content, not just numbers and arithmetic. Everyday Mathematics is designed to enable elementary aged children to be lifelong mathematical thinkers.

Every strand within the program is addressed at an age and grade-appropriate level every year, with major concepts presented five different times (and often in different ways) over two-year spans. This instructional strategy is referred to as the "two-five rule."  The Everyday Mathematics strands are as follows:

• Numbers & Numeration
• Operations & Computation
• Patterns, Functions, & Algebra
• Geometry
• Measurement & Reference Frames
• Data & Chance
