This Sketchpad activity, which opens on Geometer's Sketchpad as well as on iOS with Sketchbook Explorer (cataloged separately), allows students to be informally introduced to a rectangular array model of multiplication in this series of three games. Learners subdivide a rectangular array into strips of size 1, 2, and 5 squares and then skip count to determine the total number of squares in the array. A three-minute movie provides detailed instructions and downloadable PDF of teacher notes and student worksheets are also included.
