Fourth graders at Oasis Academy recently turned their classroom floor into a hands-on math lab, bringing geometry to life in an unexpected way.
Large shapes were taped onto the floor — rectangles, polygons, and even an L-shaped figure — and students were given stacks of letter-size paper with a simple task: measure the area and perimeter of each shape using only the sheets of paper as their measuring tools.
Working in small groups and rotating through each shape, students carefully placed the paper inside the outlines to cover the space without overlapping. As they counted the sheets they developed a concrete understanding of area as the amount of space inside a figure.
The lesson then shifted to perimeter. Students lined the sheets along the taped borders, discovering that while two shapes might have similar areas, the distance around them could be very different. The activity sparked curiosity and teamwork, with students adjusting, recounting, and refining their strategies.
“Students always enjoy using tools to explore their learning, rather than just plugging numbers into a formula on a workbook page or computer screen,” said Rebecca Farley, Fourth Grade Teacher. “When they’re on the floor discussing the concept and strategizing together, that’s real mathematical thinking happening.”
“Those are the light-bulb moments — the reason we teach. The excitement, teamwork, and thoughtful conversations showed me that the learning truly stuck,” she said.
