This activity uses coins or chips (each side is different) to simulate population growth. The students have a bag of ~70 coins or chips.
The student (working independently or in pairs) simulates exponential population growth with the coins or chips by following the directions included with this product.
The activity represents the growth of Wildebugs (fictitious bugs) over a period of a few years. The students dump a number of chips from a cup, add more chips to the "population" according to how they land, and repeat. The recording sheets record the data as the students continue with the activity.
A grid is included so that the student may graph their data and see the exponential function visually.
My students have loved this activity because of the hands-on and visual aspects of the activity. It is a nice way to introduce or reinforce exponential functions. The recording sheets include comparing the modeling of exponential growth and calculating the growth from a multiplier.
