Over a decade's worth of materials developed by the Preparing to Teach Mathematics with Technology project are available in the FREE PTMT portal. Both instructors and college students can enroll to access materials. The PTMT materials include several units that help teachers consider math ideas, good pedagogy, and learn skills with different technology. Many have used in online methods courses!! Modules focus on Geometry, Data Analysis and Probability, Algebra, Statistical Investigations, Voices from the Field (classroom videos and teacher interviews). Over the years our author team includes myself and several very active AMTE members: Karen Flanagan Hollebrands, Allison Waling McCulloch, Jen Nickell Lovett, Charity Cayton.
