About the Activity: In this activity, students will use ratio and proportion to estimate the population of deer in a forest. Students will manipulate concrete objects that are instructional in formulating and testing their thinking and understanding of ratio and proportion. Using “tag and recapture” process the goal is to predict the number of deer in the forest. With their findings students can come to the conclusion on issues such as over population, when hunting season should be, whether the season is right for hunting and many more.
