Second Look - Measurement

Wondrous Tales of Measurement
A 5-day mini-unit taught to third graders to address the concepts of measurement, angles, and circumference through literature. Includes example activity sheets.

Investigations: A Mathematical Measurement Mystery
An activity about mysteries focused on teaching measurement. Investigations are hands-on, open-ended activities that encourage problem solving, reasoning, communication, and mathematical connections. Investigations is a regular feature of Teaching Children Mathematics and highlights activities that develop conceptual understanding of mathematics topics.

The Power of String: Building a Conceptual Foundation for Measuring Rate
How students build a conceptual foundation for measuring rate through the use of engineering devices such as: Lego robotics, interactive, multimedia, and a simple string.  Student work and data collections samples are also discussed.

Illuminations Lesson: Competing Coasters

In these activities, students look at attributes that vary from coaster to coaster, attributes that make each scream machine uniquely thrilling. Students use a Web site to view photos of roller coasters from around the country. Based on the pictures, students predict which coaster is faster, which is higher, which goes farther, and which takes longer. They look up data on another Web site to check their predictions. Finally, students evaluate their estimates of speed, height, etc., to see whether their estimation skills improve with experience.
