My new blog is http://dmcpress.org and it will continue to inform my vision. See SAMR image below. In some recent posts (here…

Parent Who Criticized His Son’s Math Program Is Sued By Curriculum Company

Read moreWanna do* Adventures
In our investigations of children’s understanding of the mathematics of data, we identified ideas that were particularly interesting or empowering to children, and watched where they spontaneously made mathematical games and challenges for themselves. Interwoven with this process was our own deepening understanding and enjoyment of this branch of mathematics. Taking cues from children’s aesthetics…
Read moreDoing Dynamic Math & Tech Adventures
Helping students to improve their problem solving ability is one of the major goals of mathematics education. The dynamic math approach is intended to help facilitate that ability. Preliminaries Students should be organized for small groups activity. Each group chooses a “captain” who will be responsible for sharing his groups decisions. Room arranged appropriately for…
