Data sets can be organized in a variety of ways, including line plots. How can you use addition and subtraction to help solve world problems in How can line plots and other tools help to solve measurement problems? In addition to, in-depth inferences or applications that go beyond level. For analyze the best way to display the data set.(pie chart, line graph, bar graph, pictograph, etc.) based on a line plot, provide 2 3 different interpretations/conclusions that you can reach from the data set. 3.5 In addition to performance, in-depth inferences and applications with partial success. make a line plot to display a data set of measurements in fractions of a unit (1/2, ¼, 1/8). (4.MD.4) solve problems involving addition and subtraction of fractions by using information presented in line plots.
