This lesson plan offers the cool math surprise that "odd numbers hide in squares!"
Students also explore "where do even numbers hide?"
This is a detailed, classroom-tested lesson plan, with a script of teacher prompts/questions (and answers).
Students will be eager to go home and share their math surprise with family and friends. A letter/form for parents is included, to send you feedback on what their child shared and what they themselves learned.
Materials needed are linking cubes (or similar), square grid chart paper, and markers.
