UNIT PREPARATION

Gather 12 metersticks or yardsticks. See Lesson 5 Material Preparation.

Display the Math Practices page where all students can see it.

Prepare copies of the Centimeter Graph Paper Master for the unit. Students will need about 10 copies.

Students will need the following tools readily available for the Daily Practice and Problems items in this unit:

LESSON SESSIONS DESCRIPTION SUPPLIES

LESSON 1

Getting to Know
Room 204

 2 Students are introduced to Room 204, a fictional classroom of 22 children, through a class picture, data table, and graph. Students analyze Room 204's data as well as collect, organize, and graph data that describe their own classroom. Students are introduced to the terms variable and value.
  • chart paper or poster-size graph paper

LESSON 2

Getting to Know
Room 204
a Little Better

 2 Students distinguish between categorical and numerical variables. They collect, organize, and graph numerical data that describe themselves.
  • easel paper or poster-size graph paper

LESSON 3

An Average Activity

 2 Students make predictions and generalizations about students in Room 204 and their own classroom using the median to average data.  

LESSON 4

The Four Servants

 1 Four servants (Artist, Table-Maker, Grapher, and Answerer) help a young prince find the golden bird that will save his father's life. The story is a variation on traditional magical helper folk tales. The story revisits the TIMS Laboratory Method.  

LESSON 5

Arm Span vs. Height

 4–5 Students collect data to model the relationship between the arm span and height of their classmates. They then use these models to make predictions and generalizations.
  • metersticks or yardsticks
  • rulers
  • calculators
  • red pen or marker
  • masking tape
  • poster-size graph paper
  • blank paper

LESSON 6

Workshop: Graphs and Averages

 1–2 In this Workshop, students solve problems to practice or extend the data concepts explored in this unit. They choose problems that match their ability to describe a data set represented in a bar graph, find the median, and make predictions and generalizations about a data set using a median.
