Algebraic reasoning and geometry are intertwined, and exploring one often leads to connections to the other. In this 75-minute webinar, we will begin with a hands-on geometry activity designed for children and adults to do together, then move to an informal introduction to linear graphs with adult learner activities.


    This professional development activity/course is designed for:

  • Adult education teachers at all levels of math ability and comfort

In this webinar, we will explore how to create a wheeled toy for a young child out of materials found around the house, which can launch an investigation of circles appropriate for both children and adults. Activities will include discovery of the relationships between the parts of a circle, estimating measurements, and using those relationships to explore graphing data. Activities will begin with concrete measurement and extend to more abstract reasoning. This fulfills adult learners' needs in their dual role as caregivers of children and learners of mathematics.

    Learning Objectives

    Upon completion of this professional development activity/course, you will be able to:

  • Create a wheeled toy for a young child and share the activity with your adult students
    Connect abstract geometry topics to a real-life concrete example
    Informally explain what pi means and how it relates to the circumference of a circle
    Build from geometry concepts to graphing data
