Using Proportions to Estimate Fish Populations Simulation: Capture - Recapture

Show your students how proportional thinking is used by scientists to estimate wildlife populations using a capture - recapture process. In cooperative groups, students will use a lake (paper bag) full of fish (beans) to capture, tag, recapture, and record their findings. They will use their data to write proportions and estimate the total number of fish in the lake. Students will use easy-to-follow instructions on an editable Google Slides presentation and record their data and work on an included paper. Supplies needed (per group) include: paper bags, dry beans (or other item to represent fish), and small paper cups - all found at most dollar stores.
