Unit 1 of our new math program has first graders focusing on organizing and representing categorical data. During this exploration, mathematicians began by sorting objects into categories of their choice, describing their categories, and counting the number of objects in each category. Currently, students are learning to collect data by conducting a survey and recording and organizing that data in a way that makes sense to them. Some represented the results using objects, symbols, tally marks, or numbers. They are also making sense of one another's representations.
