First graders observe and measure their shadows. They go outside at three hour increments during the course of a day. Each time students measure and record the length of their shadows. Students read books about shadows and discuss why...

Fourth graders investigate a range of circles, each with a different radius, diameter and circumference and assemble this information in their search for relationships.The measurement of circles and the relationships to be found within...

Students convert English to metric units. In this math lesson, students give examples of measurements they encounter in their daily lives. The share their answers in class.

Students calculate the length of a side of a triangle using a trigonometric function. They calculate the measure of an angle given two sides of a triangle with a trigonometric function.

Students design and construct a suspension bridge. Math is used to compare the actual measurements of the bridge to the student's version.

Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

Young scholars analyze rocks. In this geology lesson, students collect rocks from the schoolyard and sort them according to various characteristics, such as color, size, and weight.

Students collect and sort rocks based on visible characteristics.  In this statistics instructional activity, students determine adequate sample size and categorize rocks based on characteristics.  The book Everybody Needs a...

Students create a Hexaflexagon using a formula. In this calculus lesson, students apply the definition of delta epsilon as it relates to limit to create a shape using creases. They relate the same rule to triangles and investigate angles.

Students explore Earth science by identifying types of rocks in their schoolyard. In this geology lesson, students collect a group of rocks from their playground and categorize them based on color, shape and size. Students read the book...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Hands-on and real-world applications are great ways to teach mathematical concepts. Creative thinkers examine how ratios are used to create scale models of buildings and structures. They practice working with ratios by looking at a map...

A couple PowerPoint presentations are used to stimulate discussion about the perspectives of different countries on the issue of energy consumption. Afterward, they play a game in which each team is assigned a country, considers its...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson plan series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Looking for a different approach to triangle congruence criteria? Employ transformations to determine congruent triangles. Learners list the transformations required to map one triangle to the next. They learn to identify congruence...

Trying to understand the vastness of outer space can be quite a challenge for young scientists. Help put things in perspective with this cross-curricular activity as students work in pairs creating scaled models of...

What makes a good monarch? Elementary and middle schoolers examine popular symbols of the British monarchy before designing a television advertisement about the qualities needed in a monarch. Next, they write poems using metaphors and...

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

Students define the parts of a database, search strategies to locate information electronically, create/modify databases, etc. and enter data into a prepared spreadsheet to perform calculations.

A lesson involving mapping, the use of a compass, writing and following directions, and exploring the first two themes of geography is here for you. Learners create original maps that show the routes they take through their own...

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...

This page includes a space to write in the date, but what does the date even mean? And where does it come from? Inform your class about the various calendars and how the Western calendar came into widespread use with an informational...

Wrap up a lesson on surface area with a resource that asks scholars to use the idea of wrapping paper to investigate surface area. They draw representations of rectangular prisms on graph paper to find the areas of the respective...
