A line plot shows data with X marks stacked above a number line. This 3rd grade making line plots from data worksheet has two items, numbered 1 and 2, on grid paper. In item 1, Aliya tracked the scores of people who played an online game. Her tally chart lists the scores 1, 2, 4, 5, 7 and 9, with a group of tally marks next to each one. In item 2, Mrs. Read counted how many books people checked out from the library. This time, the data sits in a frequency table, from 1 to 6 books. Your child draws one line plot for each item, so there are two plots to build. A mother and her son read together beside item 1. Page two shows both line plots, with a key that says one X is one person.
