Overview
All living things eventually die. How long an organism is often dependent on a number of factors. In this lesson, students will have the opportunity to explore some of these factors by comparing the life spans of a variety of Arizona animals. In the process, they will perform two-digit subtraction and develop pictographs. This lesson can be enhanced by reading How Many Candles? by Helen Griffith.
