Boxes & Blocks: Square Play
Students add a new angle to block play with this spatial challenge. In this early childhood math lesson, students use creative-thinking, patterning, visual-spatial, and fine-motor skills to explore the different shapes that can be made...
Curated OER
Geometry Jeopardy
Students identify the pattern in a problem. In this geometry lesson, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.
