Multisensory Math 1 Intensive (Winter 2020)

Instructor: Marilyn Zecher

Course Description

Based on the Orton-Gillingham philosophy of teaching, Marilyn Zecher's Multisensory Mathematics I applies the research-based Concrete-Representation-Abstract (CRA) approach to teaching mathematics as advocated by the National Math Panel and the NCTM. Participants learn to apply this methodology in guiding students from foundation skills and numeracy to place value, operations, fractions and decimals. Participants learn to use manipulatives effectively to reinforce concepts, aid memory and enhance performance for all students. Strategies for helping students learn and retrieve math facts are stressed as well as structured procedures for computational accuracy. This approach is especially effective with students who learn differently, inclusion classes and ESL learners. The approach is effective for initial instruction as well as remedial work at all levels and is compatible with all curricula and programs.


Multisensory Math Distance Course Pacing Guide

  • Expect to invest 3 1/2 to 4 1/2 hours per week in video viewing, taking notes, practicing with manipulatives, completing an assigned reading and participating in the class blog. 
  • Additionally there are two video conferences of two hours each offered at  in the evenings or on weekends.  You must participate in one for the first half of the course content and one for the second half.  Additional office hours and Q&A sessions may be scheduled as per participant requests. Some are scheduled in the evenings, other on the weekends. You choose. If you miss an assigned video conference, there will be one accessible by video that you can watch to make up the content. 
  • Assigned readings can be completed at any time during the course though some are of greater benefit if completed with course sections. 
  • Course Assignments  The length of time needed to devote to the assignments depends on the level of certification desired.  CEU participants - complete all videos, video conferences and three questions from the final exam.  Credit seeking participants complete all readings, the exam, and a lesson plan project which includes a 10 minute video demonstration of proficient teaching. Graduate credit applications, complete an additional university level project in lieu of a research paper. 


Next Class:  January 11, 2020   With  two online meetings with the instructors.

Multisensory Math 2 Online

Instructor: Marilyn Zecher

Course Description

Marilyn Zecher presents the follow-up course to Multisensory Math 1. Based on the Orton-Gillingham philosophy of teaching, Multisensory Mathematics II applies the research-based Concrete-Representation-Abstract (CRA) approach to teaching mathematics as advocated by the National Math Panel and the National Council of Teachers of Math (NCTM). Participants learn to apply this methodology in guiding students from foundation skills such as multiplication, division and fractions to operations in upper levels of math including Pre-Algebra, Algebra I, Algebra II and Geometry. This approach is especially effective with students who learn differently, inclusion classes and ELL learners. The approach is effective for initial instruction as well as remedial work at all levels and is compatible with all curricula and programs.

Successful completion of Multisensory Math 1 is required prior to enrolling in Math 2.

Next Class:     TBD


Study Skills Online


Dr. Anthony Henley presents Study Skills and Learning Strategies: evidence-based methods to help students improve executive functioning, test-taking skills, and comprehension. Instruction is based primarily on the SKORE method developed by Claire Nissenbaum, a Fellow of the Orton-Gillingham Academy and Founder of ASDEC. Participants will also learn to provide students with an overview of phonics and general study skills. In addition, they will learn how to boost test-taking skills that emphasize understanding directions and identifying key words. Study Skills is one of four required courses for Academic Therapy (AT) Certification. Participants may begin their AT training with this course.

Participants will learn specific methods to help students in three critical areas: Executive Function, Study Strategies and Grammar/Writing.

Next Class: February 8-April 25, 202
