Students display what they have learned about bridges as they construct their bridge. They present their projects to the rest of the class. They compare and contrast the construction of the bridges.

Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...

Students study the significance of the quantum model and how scientific theories adapt over time.  In this investigative lesson students describe the contributions that scientists have helped develop the atomic theory and identify...

Third graders sort and classify the four Arthropod classes. They are given puzzle pieces of one Arthropod example. Each group is to put their puzzle together, glue it on a piece of construction paper and label the ir puzzle.

Students use a ball to push and pull to demonstrate the concept of force. In this force lesson plan, students talk about the importance of force in space and use balls to demonstrate this phenomena.

Students analyze NASA data from the Multi-angle Imaging Spectroradiometer. In this NASA data instructional activity, students access an assigned website to examine information from the MISR on the Terra Satellite. They determine how...

Use Glencoe's Math Course 3 randomly generated self-checking quiz to test your knowledge of indirect measurement. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the...

This site gives a short interactive quiz which allows students to self-assess their understanding of indirect measurement.

Compare the lengths of 2 objects indirectly by using a third object. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

First Graders need to use direct and indirect comparisons to measure objects. Today they will use their new knowledge of dinosaurs to find the longest of the giant lizards.

Welcome to Martha's STEM Stories! STEM stands for science, technology, engineering, and mathematics. You may already know that doing STEM means testing ideas, collecting data, making calculations, and drawing graphs and charts-but you...

Dr. Math explains how to find distances indirectly by using the Pythagorean theorem.

In this inquiry-based activity, learners will work in groups to gather measurements needed to approximate the height of a building. Students will discover how geometric mean can be used to find the lengths of missing sides of right...

Dr. Math offers a way to calculate the altitude of a triangle using only the lengths of the sides of the triangle. He briefly explains how this was used by the Egyptians long ago.

This source offers videos, solutions, examples, and songs to help kids learn how to order three objects by length and compare the lengths of two objects indirectly by using a third object.

If you think you can handle the Pythagorean Theorem, then this is a math challenge you should try. Explore geometric relationships and measurement in this one page activity from the NCTM Math Challenges for Families series.

Children will learn about and explore measurement to successfully design a dog house for his or her cutout paper dog. Each section of this weeklong adventure is introduced by a video clip or online game that encourages children to...

In this week's Afterschool Adventure, children will practice and explore strategies for solving addition and subtraction problems, such as using counters and rulers, performing mental math, and drawing pictures. As children encounter...

In this video, Harry finds money on the sidewalk. He uses ratio, proportion, and some knowledge about shadows to return it to the rightful owner. In the accompanying classroom activity, students investigate whether there is a consistent...
