Mathematics teachers who participated in Rice University School Mathematics Project's 2014 Spring Networking Conference on February 1 provided material for this wonderful resource for K-12 Texas mathematics teachers. Attendees identified mathematical terms new to their grade level in the revised TEKS; these terms are bold typed.
