Engaging - Interactive - Successful

A Guide to Success with Math is a guide to understanding and teaching math based on the Orton-Gillingham Approach for Literacy Instruction. 

For some students, mathematics is a road traveled in small steps. 

A successful multisensory approach leads the student through small increments of understanding toward unifying themes in mathematics. Student’s strengths and needs must be recognized and addressed with built-in “checks for error,” as well as a built-in system for building confidence and competence.

The OG interactive, cognitive approach for learning math enables students to develop more effective ways of thinking about math and applying new skills.
