**Focus Points**

**Investigation 1 Representing Multiplication with Arrays**

**Session 1.1 How Many in a Box**

Students record and organize data about the number of items in a box and describe the shape of the data distribution.

**Session 1.2 How Tall are 4th Graders**

Students measure the heights of their classmates and use the data to describe the heights of students in the class.

**Session 1.3 How Tall are 1st Graders**

Students collect height data from a first-grade class. They create a representation of first-grade and fourth-grade height data in order to compare the groups.

__Session 1.4 ____Representing the Heights of Fourth and First Graders__

Students complete and compare their representations of the heights of first and fourth graders. They develop arguments about what the data show.

**Session 1.5 ****Representing and Comparing Data**

Students use the representations of the height data to make arguments about how their data models a comparison of first and fourth grade heights. Students complete an assessment in which they compare two data sets.
