Properties Everywhere

This lesson captures students’ interest, provides a review of the primary unit objectives, and assesses students’ prior knowledge. This experience focuses students’ attention on the attributes of objects and rules for sorting them while building vocabulary for describing attributes and for classifying objects.

Comparing Columns on a Bar Graph

During this lesson, students apply what they know about comparison subtraction by constructing bar graphs and using the graphs to answer questions.

Bar Graph Investigations

During this lesson, the students apply what they know about comparison subtraction by constructing bar graphs and using them to answer questions. They conduct a survey to gather data and then complete a bar graph. They also use the data to generate a bar graph using technology.

Freckle Face

This lesson initiates the development of skills in collecting and recording data. Students collect data about a partner's face and tally the data from the whole class. They learn the convention for displaying a set of five using tally marks. Then students create a pictograph and pose and answer questions about the data set.

The Eyes Have It

Students collect data about the eye color of class members. They create bar graphs with several classifications of data. They pose and answer questions about the data by looking at the graph, and they find the range and mode.

Up on Top

In this lesson students generate bar graphs. Posing and answering questions using the graphs gives them an opportunity to apply their reasoning and communication skills. They also consider whether a given category is likely, certain, or impossible.

Eye to Eye

Students learn to pose mathematical questions about themselves and their surroundings through class. They gather data about eye color from their classmates and another class within their school. They organize this data to answer questions.

Baby Weight

In this lesson, students work with data to complete an organized chart by doubling or halving numbers. Then, they compare data using vertical and horizontal bar graphs.

How Many Steps?

In this lesson, students participate in activities to develop concepts of measurement and statistics. Students are asked to measure distances using non-standard units and to record their measurement in a bar graph. Then they are asked to make comparisons using the bar graph.

What's the Weather?

In this lesson, students analyze information represented by pictographs. Students are asked to discuss, describe, read, write, and make predictions about the graphs and the information they contain.
