Students progress from concrete hands-on activities to the use of abstract symbols and concepts. Working in cooperative learning groups, they collect and analyze data to make generalizations and predictions about patterns they discover. Small groups of students are directed to collect all of the litter found in designated areas of the school. Examines its graph, comparing and discussing the significance of data patterns. Compares and contrasts its graph with those of other groups.

Describe in writing the effects of litter on the environment and to develop a solution for this problem. Write what our litter might tell a person from the future about us, our habits, and environment. Overall Value Promoting the achievement of several cognitive and effective behaviors, it fosters creative exploration of key concepts in mathematics and science. Students gain a clear understanding of the nature of data collection, analysis of data, and the use of graphs to present information. They also learn to identify problems that exist in their environment and to develop strategies to solve these problems.
