Lesson Plan

Create a line plot by marking a number line with evenly spaced fractional intervals (halves, fourths, or eighths of a unit) and placing X marks above the values to represent a data set of measurements

Choose an appropriate fractional scale for the number line based on the denominators present in the data set - for example, using eighths when the data includes 1/8, 3/8, and 1/2

Read and interpret a line plot to answer questions about the data, including identifying the most common measurement, the range, and the number of data points at each value

Add fractions from a line plot to solve problems such as "What is the total length of all objects that measured 3/4 inch?"

Subtract fractions from a line plot to solve problems such as "How much longer is the longest object than the shortest object?"

Multiply a fraction by a whole number using line plot data to solve problems such as "If there are 4 objects that each measure 3/8 inch, what is their combined length?"

5.MD.B.2

5.MD.B.2: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally.
