Geometry: Old McDonald's Pigpen

by Texas Instruments


In this activity, students explore – numerically, graphically, algebraically, and verbally – the mathematics involved in maximizing the area of a rectangle with a fixed perimeter.

Key Steps

  • Image

    Students will graph scatter plots, analyze quadratic functions, and determine the maximum value of a parabola.

  • Image

    Students will solve design problems that satisfy physical constraints by using geometric and algebraic methods.

  • Image

    Students will observe numeric patterns, reason abstractly, and make connections between geometric figures and algebraic expressions.
