This workshop, The Complexities of Measurement, will give participants an understanding of common misconceptions students have about measurement and will provide some tools and strategies to help students improve their conceptual understanding of this topic. The workshop will explore why it is important to study measurement in the upper elementary grades as well as why teachers need to pay particular attention to the ideas of unitization and iteration. In the final project for this course, participants will design activities for their students that promote a conceptual understanding of measurement and which are immediately useful in the classroom.
