Investigate the properties of three-dimensional figures with this Arctic-themed math lesson. Beginning with a class discussion about different types of solid figures present in the classroom, young mathematicians are then given a...

An excellent resource for a geometry class, as well as for an electrical engineering course. A thorough reference sheet covers geometric shapes such as triangles, parallelograms, and circles, as well as 3-D shapes and the Pythagorean...

In a two-part learning exercise, young geometers examine 3-D shapes and describe their attributes in a table. They will be able to draw the shape and name the number of vertices, faces, and edges. In the second part, individuals...

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

Arm your class members with the six C's of primary source analysis—content, citation, context, connections, communication, and conclusions—and help them to establish a solid system for analyzing historical sources of...

Develop a solid understanding of the manipulation of expressions to produce equivalent expressions. Given an expression, pupils rearrange it to create a new one. Their new functions must match the structure of the model expressions.

Develop a solid understanding of multiplication. The interactive provides opportunities for learners to continue building a deep understanding of multiplication. Pupils use the application to find the product of two numbers and find...

Young geometers get some solid skills practice in evaluating slopes. Beginning with the basics of slope through two points and progressing through properties of parallel and perpendicular lines, the building of skills is gradual and...

Young mathematicians examine area of different figures with the same cross-sectional lengths and work up to volumes of 3D figures with the same cross-sectional areas. The instruction and the exercises stress that the two...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

When should you use more and most when writing adverbs? Practice comparative and superlative adverbs with a review worksheet. After reading through the information at the top of the page, kids decide if they should use the...

How should pupils read short stories? Set them up for this unit with an introductory lesson that goes over the main characteristics of a short story and starts learners off reading their first short story of the unit. In order to get a...

How can you show that an item is colder than something else? Or that it is more beautiful? Use a worksheet to reinforce the concept of comparative adjectives. With fill-in-the-blanks, word banks, and multiple choice questions, the...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to learners their different roles in the activity, the teacher reads aloud a...

Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

Strengthen your high schoolers' writing with a series of steps for writing successfully. With sections on organizing an essay, choosing a topic, crafting a thesis statement, and revising a draft, the lesson encourages your class to...

What is the relationship between a hemisphere, a cone, and a cylinder? Using Cavalieri's Principle, the class determines that the sum of the volume of a hemisphere and a cone with the same radius and height equals the volume of a...

After reading an informational text detailing the ins and outs of snowflakes, scholars draw their own special design then work cooperatively to role play a snowman building scenario. 

There's something about the classic volcano demonstration that can grab any learners' attention. Scholars begin with a reading and grand conversation about volcanoes, construct an erupting volcano using vinegar and baking soda, then...

Creating buildings that reach hundreds of feet into the sky is no easy task. The third instructional activity in this series begins with four activities that engage young architects in exploring the major challenges that are faced when...

The construction of skyscrapers is no simple undertaking, involving the careful coordination and planning of many different people. The third lesson in this series explores this detailed process by first teaching children about the main...
