Students will gather data to make predictions and generalizations about a population. Similar to investigations in earlier grades, students will represent variables in a drawing, collect data, and represent that data (TIMS Laboratory Method). Students will describe and make predictions and generalizations about the population by reading data represented in tables and scaled graphs.
