Large Lot Of Teachers Instruction Materials. ASCS Formative Assessment & Differentiated Classroom materials. Most of these materials have not been used. Some do have some bending due to storage and mishandling. And some minor staining. There are also some. On ASCD materials including PDxpert. Most of these items were published and distributed in the mid 2000s. Note that the leadership paper materials seem to be incomplete in the Leadership for Differentiating instruction. This is probably due to being shuffled in the moving process. Please see photos for more info. Thanks so much for your interest.
