Data Representations

TEKS Objective

The student is expected to record and organize data using pictures, numbers, and words.

Essential Understanding

The student develops abilities necessary to do scientific inquiry in classroom and outdoor investigations.

Science Background

Setup and Collect Data: Discovery Education (website) - Information about the types of data (e.g., quantitative, qualitative) students can collect from an investigation.

Signature Lesson

Freckle Face: Illuminations Resources for Teaching Math (website) - Students collect and record information about a partner’s face, combine all data from the class, and organize the data into representative pictographs.

Supporting Lessons

The Eyes Have It: Illuminations Resources for Teaching Math (website) - In this investigation, students collect data about their classmates’ eye color and create bar graphs that organize and classify the data collected. Then they pose and answer questions based on the data, and find the range and mode.

Elaboration Lessons and Extensions

Up On Top: Illuminations Resources for Teaching Math (website) - Students generate bar graphs, which they use to devise and answer questions during an investigation related to hair color. Includes assessment and extensions.

Assessment Ideas

Have students identify a research topic on which they would like to collect data (e.g., the number of pets owned by each of their classmates). Once all data have been gathered, instruct students to represent their findings in any form that is appropriate, or in several different forms (tables, charts, illustrations, etc.).
