Math in Focus Chapter 13: Bar Graphs & Line Plots
Trimester 2
Big Idea: Bar graphs and line plots help to organize data. Bar graphs are used to compare data. Line plots show how data is spread out.
Vocabulary: vertical, horizontal, axis, scale, line plot, survey

Common Core State Standards:
- CCSS.MATH.CONTENT.3.MD.B.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
- CCSS.MATH.CONTENT.3.MD.B.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.
- CC.K-12.MP.1 Make sense of problems and persevere in solving them.
- CC.K-12.MP.2 Reason abstractly and quantitatively.
- CC.K-12.MP.3 Construct viable arguments and critique the reasoning of others.
- CC.K-12.MP.4 Model with mathematics.
- CC.K-12.MP.5 Use appropriate tools strategically.
- CC.K-12.MP.6 Attend to precision.
