Overview

Number Play is a virtual simulation tool that can be utilized during math workshops to support the investigation of numbers, quantities, cardinality, and subitizing. The simulation can be scaffolded by teachers and utilized by students in a variety of ways: subitize to 5, subitize to 10, predict the next number in a sequence, identify the number of objects in a set, and count objects to 20. Through purposeful play, students can explore and demonstrate their understanding of these concepts by utilizing the simulation platform. This tool could be used at the beginning of a mini-lesson (such as a form of number talk) or during math workshop as a task for students to engage with.
