Hands-On Geometry for Struggling Math Students

My students need Polydrons, like the Pyramid Set, the Geometry Classroom Set and the Archimedean Solids Starter Set, for hands-on exploration of geometry concepts to develop concrete understanding, especially with three-dimensional figures.

Hooray! This project is fully funded

My Students

Geometry can seem very abstract, especially three-dimensional geometry, but it doesn't have to be. I want my students to able to explore geometry in a way that is meaningful and engaging- manipulating various Polydron pieces to create and analyze attributes of many different shapes.

I teach 8th graders who have a lot of difficulty with math.

To get them the help they need, they take a Math Intervention class in addition to their grade-level math class. In Intervention, we work on basic and foundational math skills to fill in gaps or misconceptions in numbers and operations, geometry, measurement, algebra, and data analysis and probability, as well as logic and problem solving. This ensures they have the prerequisite knowledge needed for the higher-level math concepts that they learn in current and future math classes. I teach in a low-income area of Austin, Texas. Many of my students' parents did not complete high school or barely speak English. These kids need all the opportunities they can get. One great opportunity they do have is a second, small-group math class with a teacher dedicated to meeting each of their individual educational needs, helping to develop a strong foundation on which they can build the more challenging math concepts in future classes.

My Project

My students will get a concrete understanding of geometry through these various types of Polydrons. Instead of a lecture, they will learn through experience manipulating the materials. Discussion will follow, strengthening students' understanding as well as their mathematical communication, helping them retain and internalize the concepts.

These Polydrons will allow my students to explore geometry in a meaningful way- with their hands, where the concepts are concrete and tangible.

Hands-on learning really helps to bridge the gap and make mathematics accessible to all students, especially those in my intervention classes. Please help support this project to make their math intervention even more engaging, productive, and successful, and promote mathematics success in their futures!
