Visualizing the Maximum Area of a 4-Sided Rectangular Enclosure

Increasing Spatial Reasoning Skills: Optimization of Measurement

Visualizing the Maximum Area of a 4-Sided Rectangular Enclosure

In the past, when introducing the concept of Optimization of Measurement, students would complete a series of investigations involving different lengths of rope, fence, etc. and would make connections from the table of values and graph they would produce. While I still intend to do some of the investigations, I want to make them more real and especially more visual to hopefully help students better retain the knowledge and develop a deep understanding.
