CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

This is a remix of Alike or Different Game from Illustrative Mathematics, https://tasks.illustrativemathematics.org/content-standards/tasks/515.  The purpose of this activity is to give students practice classifying objects according to one attribute to support sol K.12.  The teacher gives each student an object.  They travel the room with their hand raised to find another student to compare their object with.  They compare to see if the object is alike or different and how (color, size, shape, thickness).  They trade objects and travel the room to find someone else to compare with. 

The first day of Kindergarten is long anticipated by parents and young students. Students expect school to be a dynamic and safe place to learn, an objective that is realized immediately by their involvement in purposeful and meaningful action. In Topics A and B, classification activities allow students to analyze and observe their world and articulate their observations. Reasoning and dialogue begin immediately. In Topics C, D, E, and F, students order, count, and write up to ten objects to answer ‘how many’ questions from linear, to array, to circular, and finally to scattered configurations wherein they must devise a path through the objects as they count. In Topics G and H, students use their understanding of relationships between numbers to recognize that each successive number name refers to a quantity that is one greater and that the number before is one less.

In Module 1, students began the year observing their world. What is exactly the same? What is the same but...? They matched and sorted according to criteria sequenced from simple to complex. Their perceptions evolve into observations about numbers to 10.

This sorting activity allows the students to explore several hands-on tasks that will encourage the students to use critical thinking skills to categorize and logically sort items by one or more attributes.

Sorting and classifying objects according to attributesMathematics Instructional Plans (MIPs) help teachers align instruction with the  Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.
