Newton, MA : EDC, 2009. Mathematics Improvement Toolkit Collaboration and Co-Teaching, a workshop for mathematics and special educators, focuses on ways in which teachers can collaborate within a co-teaching model to support all learners, particularly those with mild to moderate learning disabilities receiving the general curriculum. This tool, developed at EDC, Inc., provides all the information and materials needed by school-based facilitators to conduct the 5-hour workshop. This workshop should be facilitated by experienced math or special education teachers, teacher leaders, or curriculum specialists. Since this workshop is about collaboration and co-teaching, it is ideally co-facilitated by two individuals, one with expertise in teaching math and one with special education teaching expertise. 20100504.
