    Instructor: Marilyn Zecher

    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.

    Program Dates:
    April 7 - June 23, 2018.
    With two 90 minute online sessions with Marilyn Zecher.

    ASDEC faculty present Sounds In Syllables (SIS), one of the most powerful Orton-Gillingham based methods designed to teach reading (decoding, fluency, and comprehension). These methods integrate research-based evidence from neurology, cognitive sciences, psychology, speech-language pathology, and linguistics to produce the most durable remediation for students with even the most severe learning disabilities.

    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.


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

    Language Foundations (also known as “Structured Language Basics – SLB) is an Orton-Gillingham based multisensory approach to teaching reading-language arts skills in an inclusive classroom.  This curriculum is equally successful with elementary, secondary, and adult students for whom reading and spelling present significant problems.  More importantly, the use of Language Foundations in the primary grades can act as a preventative measure for difficulty with reading and spelling in the later grades.


    Over 9,000 teachers have been trained in Language Foundations (LF) with research indicating substantial improvement among students receiving LF instruction.  Teachers deliver a scripted curriculum of 125 multisensory lessons that provide instruction in reading, spelling, grammar, handwriting and composition. In addition, teachers receive a full kit of instructional materials. Teachers are not required to make additional instructional materials. The comprehensive materials tool kit includes teacher manual, manipulatives and student kits.
