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

• To show data in a bar graph

• To represent data in a pie chart

What does each 'X' represent in the insect length line plot?

• The number of different insect species

• The total number of insects

• The length of one classroom pet insect

• The average length of insects

How do you find the most common insect length in the collection?

• By counting the number of insects

• By subtracting the shortest length from the longest

• By finding the length with the most 'X's above it

• By adding all lengths and dividing by the number of insects

What is the difference in length between the longest and shortest insect?

• 6/8

• 3/8

• 1/2

• 7/8

How do you calculate the combined length of insects measuring 4/8 of an inch?

• By subtracting 4/8 from the total length of all insects

• By dividing the total number of insects by 4/8

• By adding the numerators of each 4/8 measurement

• By multiplying the number of insects by 4/8

How many boys ate pizza at the party?

• Fifteen

• Thirteen

• Ten

• Eight

Which fraction of pizza was eaten the most?

• 3/8

• 4/8

• 5/8

• 2/8

Did more boys eat 4/8 or 5/8 of the pizza?

• 4/8

• 5/8

• Neither, as most ate 3/8

• Both were eaten equally

How many boys ate at least half of the pizza?

• Seven

• Six

• Eight

• Nine

What is the difference in size between the most and least common amounts of pizza eaten?

• 3/8

• 2/8

• 4/8

• 1/8
