Section 1
Calculating Total Value Using Frequencies
Property
To find the total value of all data on a line plot, multiply each unique data value by its frequency (the number of times it appears), and then add all the products together.
In this Grade 5 lesson from enVision Mathematics Chapter 10, students learn to solve word problems by interpreting measurement data displayed in line plots, including reading fractional values and calculating totals using multiplication and addition of fractions. Students practice writing and solving equations to find totals and differences from real-world data sets such as rainfall amounts and string lengths. The lesson builds skills in organizing line plot data into frequency tables to support accurate multi-step calculations with fractions.
Section 1
Calculating Total Value Using Frequencies
To find the total value of all data on a line plot, multiply each unique data value by its frequency (the number of times it appears), and then add all the products together.
Section 2
Solving Multi-Step Problems with Line Plots Using Equations
To solve a word problem using a line plot, represent the unknown value with a variable (such as ).
Use the data from the line plot and keywords from the problem to write a mathematical equation.
