Lesson objective: Solve problems by generating measurement data and creating a line plot.

This lesson provides an opportunity for students to apply their knowledge and understanding of line plots to a real-life situation. Students are asked to solve for how many different sizes of sacks are needed for the class based on each student's length.

Key Concept students will use:

- We can display measurement data by making a line plot.

Skills students will use:

- measurement
- represent and interpret data (Grade 1, Unit 3)

Students engage in Mathematical Practice 1 (Students will make sense of problems and persevere in solving problems by generating, collecting, and interpreting data) as they measure and record their lengths, and as they create their line plots to find out how many sacks they need for each length.

**Key vocabulary: **

- measurement

**Special materials needed:**

- cenitmeter
- data
- inch
- ruler
- yard stick
