# Algebra Patterns and Functions

## Knowledge base & tools to develop mathematical literacy

### Knowledge base

Mathematical knowledge base with concepts necessary for learners to conceptualize to become mathemtically literate and misconceptions that must be over come. Particularly important for how learners develop their understanding for algebra, patterns, and functions are:

*Concepts related to:*

- Algebra & Patterns
- Ratio & proportion
- Concepts and Outcomes from Science for All Americans (SFAA) & National Assessment for Educational Progress (NAEP)
