  ASDEC provides the only Orton-Gillingham Based program endorsed by the International Dyslexia Association in the Washington, DC region. The program provides intensive instruction in reading, writing, spelling, and handwriting. Physical movement is added to the visual and auditory stimuli to provide multisensory learning. The hands-on aspect of the structured routines facilitates attention and concentration. The careful development of conceptual understanding and the high level of repetition reinforce memory. All activities build on the mastery of skills, which helps students build self-esteem as they experience success each day.

  Program Dates: July 7-25, 2025

  Getting Ready for Middle School –  Rising 5  (depending on pre-assessment) and 6th Grade Students

  This summer review program is appropriate for students who have language based and/or related disabilities who have significant gaps in their skills and conceptual foundations. We will cover basic numeracy and place value concepts with a focus on fractions as they relate to whole numbers. We will explore the concepts surrounding multiplication and division but we will not drill math facts for rote memory.  Rather we will explore patterns which aid reasoning and memory in a more humane way of addressing these deficits common to students with language-based disabilities.  We will stress the long division algorithm, and multidigit arithmetic which form the core of middle school math.  Our final week will be devoted to fraction and decimal concepts. Students must commit to attending all three weeks of the program and no exceptions will be allowed.  Students must be able to function in a group as well as independently with instructor support.

  Multisensory Math 1 Online

  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:
  July 9-September 22, 2025

  With two 90 minute online sessions  with instructors - evening and weekend options available. Scheduling of online sessions will occur after the start of the class.

  You will receive instructions to login to the course on the first day of the course. 
  

  You will receive your math manual  by the first day of the class. Please provide a SECURE mailing address for delivery of your math manual.

  Refund Policy

  Courses: 50% if withdrawal is at least ten working days before the start of class. No refunds are available less than 10 days prior to the start of class. If a course is sold out, ASDEC will not refund payment at any time.  For more payment details please go to: http://www.asdec.org/ASDEC_payment

  MSM 2 Online 

  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.

  
  

  Online meetings: Dates to be determined with instructor after the course opens.

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