Abstract

This workshop introduces users to the Spirals Excel file which was developed to encourage exploration of the relation between geometric and numeric patterns for young learners. This can create a firmer understanding of multiplication, division, and fractions even before these concepts are formally introduced in a highly interactive and visual fashion. Such explorations may feel more like creating art than learning math. Although developed for independent exploration, the Spirals file could readily be employed in classroom settings for students with Excel-enabled tablets, or via smart-boards to amplify a variety of topics in elementary and early secondary education.
