The purpose of this Warm-up is to introduce the students to a new routine called Notice and Wonder, which will be used throughout the year. This routine provides an opportunity for all students to contribute to the conversation and for the teacher to listen to what knowledge students already have. In this Notice and Wonder, students share ideas they have about connecting cubes.

A picture of connecting cubes is provided. However, it is preferable to display a collection of actual connecting cubes. Students should have at least one connecting cube to examine up close.
