### Lesson plan

# Let's Play Ball

#### Learning Objectives

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

*(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.

#### Differentiation

**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.
