The Sorting Activity is a great math center/station for your classroom! In this activity, students are given 12 numbered tiles to arrange in three separate categories using common characteristics. The catch: students do not know the common characteristic of each category!! My student find this activity fun, but challenging! This particular version focuses on the topic of divisibility. This download includes; the full answer key, the common characteristic printable template sheet, and the printable "cut-out" number tiles!
