On a teacher-designed individual screening for graphing, less than 25% of kindergarten students demonstrated knowledge of graphing which requires students to collect, organize, represent, and interpret data. A Tn Math K-2 Content Standard is STATISTICS AND PROBABILITY: In order to develop an understanding of Statistics and Probability, the mathematics curriculum must include problems which require students to collect, organize, represent, and interpret data; make inferences and predictions; present and evaluate inferences and predictions; present and evaluate arguments based on data analysis; and model situations to determine theoretical and experimental probabilities. Learning Expectations:
Through the investigation of meaningful problems, individually or in cooperative groups while using appropriate technology, students in K-2 should be able to:
· collect data by observing, measuring, surveying and counting;
· demonstrate a variety of techniques for representing and organizing data such as arrays of physical objects, tallies, pictographs and bar graphs;
· interpret data by identifying patterns and relationships, considering cause and effect, and drawing conclusions;
· articulate specific questions based on collected data;
· determine and justify the relative likelihood of simple chance events.
The Teacher Survey items to be addressed are: "Students find ways to use what they learn, and students understand how they can best demonstrate what they know about topics."
