Mathematical Thinking can be seen as a task, enrichment, or a starter in the classroom. Regardless, it is a problem that makes students think while supporting the CCSS standard listed utilizing the Mathematical Practices.
This Mathematical Thinker is the byproduct of a discussion during a professional development session. It just kinda popped out of my mouth. Students physically move doing factors. It is also very quick. Great lesson starter.
This thinker is designed to go with Grade 3 EnVision Topic 4 lesson 3 but will work with any lesson instructing towards 3.OA.5.
