Problem setting: Cassandra and her brother Craig want to raise frogs in their back yard. They bought 16 meters of tall fencing to build a rectangular fence to hold the frogs.
Independently collect and explore data: Use the geoboard in the handout to draw all the different rectangular pens that they could build with their fencing. Each pen must use all 16 meters of fencing and should use the dots as corners. Make a table to record and organize the data.
Using the Geoboard applet from the National Library of Virtual Manipulatives.
