Let's Play Ball
Students will be able to collect data and plot fractions on a line plot.
Introduction (5 minutes)
- Tell students that today they will be playing a game to learn a new math skill.
- Tell them that they will use information from their game, or the game's data, to make a type of graph where the frequency of an item is recorded along a number line called a line plot.
- Explain to students that they will be making a data chart, which is used to organize the data, and a line plot, which shows data on a number line to show frequency.
Explicit Instruction/Teacher Modeling (15 minutes)
- Demonstrate how to create a data chart. Give students an example problem. Example: A group of 5 students are supposed to read 8 books over the summer.
- Tell students that you're going to make a data chart to show how to record the information from about the students.
- Draw a data chart where the left column is labeled "students" and the right column is labeled "books read."
- Explain that you will record the number of books read as a fraction out of eight.
- Tell students that the numerator is the part, or number of books the students have read, and the denominator represents the total of the set, which in this case is eight for the total number of books.
- Fill in the chart with your own data. Explain that when a fraction is 3/8, it means that a student read three out of the recommended eight books.
- Explain that with this data we can create a line plot to show frequency, or the number of times a certain outcome occurs.
- Draw a line plot and show with Xs and fractions where the data would be placed.
- Ask students to find the most frequented number of books read.
Guided Practice/Interactive Modeling (15 minutes)
- Explain to the students that they are going to play a game of silent ball. Let them know that after they are put into groups they must make a data chart.
- On the left side they need to label the column "Students" and write the names of each person in the group.
- Have students label the right column "number of catches."
- Each student will be given 6 chances to catch the "silent" ball. Tell students that it is called the silent ball because there is no talking.
- Ask the students what they think the denominator should be. They should answer "six."
- Tell your students to create the line plot. Taking data from various groups, brainstorm what fractions should be used on the graph.
- Place the students in groups.
Independent Working Time (15 minutes)
- Tell the students that after each person's turn they should place the data next to there name on the data chart. * Tell them to make sure that they record all the data before plotting it on the line plot.
- Monitor their work as they are recording their data on the chart.
- Enrichment: Students that are more advanced can find the range, mode, and average of the data. They can also complete the Skiing Time Averages worksheet.
- Support: Match students that need extra support with a peer to help them correctly record the data.
Assessment (10 minutes)
- Have the students plot data on a data chart and plot it on a blank line plot. Check for correct placements of fractions and Xs on the line plot.
Review and Closing (5 minutes)
- Ask students why data charts and line plots are useful in the real world.
- Ask students to brainstorm what other games use data to record information, and what the relevance of this information is.
