Description: One of a series of documents describing the progression of a topic across several grade levels, informed both by research on children's development and by the structure of mathematics. As students work with data in Grades K-5, they build foundations for their study of statistics and probability in Grades 6 and beyond, and they strengthen and apply what they are learning in arithmetic. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph. Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units-whole numbers, halves, or quarters.*Teacher Advisor is 100% free.
