Sara VanDerWerf is a high school mathematics teacher who also serves as a consultant to other mathematics educators. Mathematics tutors and teachers will find a number of resources and ideas that may be of interest in her blog. These resources include classroom activities, lesson plan ideas, teaching reflections, and links to relevant outside resources. In one recent post, VanDerWerf discusses five things elementary school teachers can do to prepare students for secondary mathematics classes. VanDerWerf developed this list with Laura Wagenman, an elementary school math educator. In another recent post, VanDerWerf shares photographs of her classroom space (which includes a "calculator museum"), accompanied by explanations of how she sets up her classroom. In another post, she describes a "stand and talk," which is a variation of the think-pair-share activity designed to increase student engagement.
