Using TIMSS Videos to Improve Learning of Mathematics: A Resource Guide
Proof Lessons by Topic
Some TIMSS video lessons fit together in ways that will be helpful to pre-service and in-service teacher educators and professional developers as they plan a sequence of meetings with teachers. Following is a grouping of lessons by topics. Teachers need not strictly follow the recommended lesson order, but what is given here is the result of extensive viewings of these videos. There is no recommended order for the overall topics, since this will vary from one setting to another.
