This sequence of activities introduces the ideas behind the Pythagorean Theorem to young children using an "intellectually honest form" that grounds complex mathematical ideas in tangible, visual models. It progresses from counting and shape identification in early grades to calculating area through unit squares, eventually exploring right triangles on coordinate planes. By incorporating 3D-printed puzzles and visual prompts, this approach allows students to engage with "big ideas" without abstr

This is a classic number puzzle. Great for family nights, PT meetings, and send-home math activities. It can also be used to introduce the idea of base-two numbers or binary numbers.

Cube-Inspired Mathematical Explorations (Grades 3-6)This is a lesson plan I put together for my student teachers to learn about the art of lesson planning. It has all the major components found in a professional lesson plan with detailed descriptions of activities and student-teacher interactions. The cube is a common object and a mathematical gem; it can be approached from multiple levels and multiple perspectives. Have fun teaching and learning. lgbu
