Second graders examine the attributes of two-dimensional shapes. In this geometry lesson, 2nd graders play a game in order to identify two-dimensional shapes and to name them.

Sixth graders build figures out of tangrams. In this symmetry lesson, 6th graders view tangrams and identify the polygons included in them. Students divide into groups, identify their tangram pieces, define the lines of symmetry, and use...

In this learning exercise, learners review topics from Algebra 2. Topics include synthetic division, rational algebraic expressions, quadratic functions, imaginary number, composite functions, and inverse of a function. The three-page...

Fourth graders draw pictures and diagrams as they attempt to solve a mathematical problem involving the arrangement of eleven tables shaped like equilateral triangles and the seating of exactly twenty-five people.

Art is a form of expression that can be controversial, obtuse, and completely driven by the political and social times. Explore Nouveau Realism and Pop Art, which exemplify the nature of modern thought and expression. This visually rich...

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

Third graders are challenged to use scientific thinking, they experiment and observe which objects are attracted to a magnet. Pupils use the evidence to construct an explanation as to what common property the objects attracted to a...

Scholars find a pattern from a geometric sequence and write the formula for extending it. The activity includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Encourage mastery of demonstrative adjectives and demonstrative pronouns. Try out the presentation to introduce your class to the concepts and practice with two integrated exercises. The At a Glance tab and Full Lesson tab can be used...

Messenger's sun shade measures 8 ft x 6 ft and will have temperatures reaching 700 degree Fahrenheit on the outside while maintaining a cool 70 degrees underneath. In the third activity of four, groups discuss the basic properties of...

Functions require an input in order to get an output, which explains why the answer always has at least two parts. After only three multi-part questions, the teacher can analyze pupils' strengths and weaknesses when it comes to...

How are forces and motion important to a swing set? Scholars explore the concepts of force and motion using swing sets. In preparation for their own STEM design project, individuals take surveys and data from peers, complete labs on...

Introduce emerging engineers to the process of metal plating. This resource provides background reading on chemical engineering, plating, and corrosion. It concludes with a copper plating activity. The standards alignment list includes...

Speed up the class's understanding of acceleration with a presentation! The resource includes a definition, example problems, acceleration due to gravity, and a graphical representation of acceleration.

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

Students investigate orthographic drawings. In this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.

High schoolers create a contour drawing of a hand creating an illusion of depth. After a brief demonstration of contour drawing, students practice by creating pictures of various objects. The final project consists of creating a...

Students explore photography by utilizing digital cameras. For this 3 dimensional lesson, students create eye glasses using red and blue acetate in order to view 3-D images. Students utilize computers and digital cameras to enhance...

Students investigate the concepts related to observing two dimensional objects. They also build three dimensional objects using the two dimensional objects. The students give an oral or written explanation for how the pieces fit together...

Third graders examine two-dimensional objects and create a 3-D image of the object. They make models of the Taj Mahal and buildings in Delhi.

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Recognize the tense used in each sentence. This online resource requires learners to select a verb tense from the choices presented. There are 10 sentences to work with, and the answer pops up immediately after a selection is made. 

Double the dimensions, quadruple the surface area. Pairs build similar prisms and compare the ratios of their surface areas and volumes to the ratio of the heights. Given two similar cones, partners determine the ratios of the lateral...
