We started our data unit today. This week we are introducing some new vocabulary terms.
Data, survey, tally marks, tally chart, graph, bar graph, picture graph
During this unit, students explore concepts of data analysis involving up to three categories of data. Students collect, organize, represent, and interpret data. Many of the problems about data are structured to represent a variety of addition and subtraction situations like those they worked with in Unit 1. A Big Idea that connects most of the work in this cluster is that data can be presented in graphs and charts, and a variety of questions can be answered by collecting and analyzing data.
