In this constructions and loci worksheet, students create a scale drawing of a running track. They identify the starting positions for a given race. Students bisect angles. They construct an angle trisector. This three page worksheet...

Students explore U.S. History by analyzing the Great Depression. In this economic instability instructional activity, students read fictitious accounts of a farm dealing with the loss of a Strawberry Farm and discuss the reasons behind...

Learners practice theories dealing with equals sign used as a balance, inequality symbols and practice utilizing a box or some other geometric shape to represent an unknown number. They assess numeracy problems embedded in language-rick...

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson plan, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional...

Students identify tangents, chords and secants. For this geometry lesson, students graph circles and identify angles created by secant lines, tangent lines and chords.

Students collect data and crate a distribution sample. In this statistics lesson, students compare and contrast their collected data. This assignment requires the students to be comfortable with navigating the internet.  

Young scholars learn how to make patterns. Students first display their prior knowledge of patterns before delving into the lesson. They complete a worksheet and participate in a web-based class activity. They work in cooperative groups...

Students calculate the altitude of triangles.  In the web based lesson, students explore the interior distance from a given point in a polygon to its side.  They compute the sum of these lengths. Students read life...

Students explore ruby-throated hummingbirds.  In this cross-curricular hummingbirds lesson, students listen to the book The Mystery of the Missing Hummingbirds and choose related topics to research with a partner. Students draw or...

Tenth graders investigate where in the real world triangles are used. For this geometry lesson, 10th graders write an essay describing where in their lives triangles are used. They can use food, buildings, clothing or anything triangular...

Learners gain an appreciation of the polygons and polyhedrons around them that make their world one of order and strength. They build polygons and polyhedrons, and then construct airplanes out of polygons.

Students analyze a set of data. They work in cooperative groups and use chain links to identify the mean, median, and mode of the chain.

Fourth graders examine specific bird characteristics and become more aware of the ecosystems that support each bird. They engage in bird walks, mapping the areas where they find evidence of bird activity.

Students make a quilt. In this geometry lesson plan, students discuss patchwork quilts and learn some different geometric shapes and patterns that are commonly used. Students explore designs with triangles and squares and then make their...

Students identify geometric patterns in quilts. In this geometry lesson plan, students view various types of quilts and identify the geometric shapes. Students construct one hundred patch paper quilts using geometric shapes.

Third graders describe 2D and 3D shapes. For this geometry lesson, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they have...

Students participate in an adding game. In this adding numbers lesson, students calculate the sum of the dice and remove a number from their activity sheet.  Students who first removes the numbers is the winner.

Students view objects sorted by one characteristic and name that characteristic.  In this sorting rule lesson plan, students explore to find a new characteristic and write a description of that rule.  In early grades the rule...

Students investigate the Sierpinski triangle and calculate the ratio and area of the triangle. In this fractals lesson, students calculate parts of a Sierpincki triangle. They use Google Earth to help them construct the different parts...

Students work together to perform simple experiments discovering the properties of air. They share their results with their classmates. They examine how engineers use the properties of air to clean the air of pollutants.

Students research native plants. They identify the plant by scientific name, size, amount of water needed and color. Pupils measure and plot an area of school property. Students create an outdoor classroom. Additional cross curriculum...

Students identify patterns found in nature. In this algebra lesson, students model situation in nature using fractals. They investigate biological geometric structures and draw conclusion based on geometric concepts.
