Chris Woodin, who teaches math at Landmark School, shares tips and strategies for teaching mathematics to students who have learning disabilities.  While the strategies are not specifically designed for students who are blind or visually impaired, many of the techniques can be adapted.  The emphasis is on teaching math through kinesthesia.  Topics included on the site are numeration; addition & subtraction; multiplication & division; fractions, decimals, percents; word problems; Algebra 1; and thematic units.  Many lessons include videos and downloadable documents to support the lesson.
