Line Plots in Grade 4 Math

Miss Gru, a fourth-grade teacher, introduces a lesson on creating and interpreting line plots using fractions. The lesson includes key vocabulary, such as data, fraction, and line plot. Students practice by creating a line plot for insect lengths and analyzing it to solve problems involving addition and subtraction of fractions. Another example involves a pizza party, where students analyze a line plot to determine the amount of pizza eaten. The lesson concludes with a recap of the learning objectives.

What is the purpose of a line plot?

• To display data above a number line

• To calculate the total of a data set
