Powerful Polygons
Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Measurement: Lesson 2
Fourth graders find the perimeter of a geometric shape by adding the lengths of the sides. They find the area of a square or rectangle by counting square units. Students use multiplication to find the area of a rectangle. They estimate...

Density Column Lab - Part 2
Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

The Good, The Bad, The Ugly
Sixth graders examine the causes of the stock market crash of 1929. In this integrated math/history unit on the stock market, 6th graders study, research, and read stocks, visit a local bank, and create a PowerPoint to show the...
Curated OER
Irregular Fractals
Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
Curated OER
Unit Perimeters and Areas
Students use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...
Curated OER
Perimeter
Young scholars explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Young scholars use the Perimeter Explorer applet to find the perimeter of various shapes.

Determining Densities
Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...
Teach Engineering
Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Multiplication Using Arrays
Explore the concept of multiplication by using arrays. Classmates use arrays to gain a better understanding of multiplication. They break arrays apart to model the distributive property of multiplication over addition. The relationship...
Curated OER
Cut It Out
Sixth graders derive an original formula for calculating the area of an irregular figure.
Curated OER
Amazing Transpiration
Learners observe a leaf and discuss the way that water is released from a leaf through its stomata. For this water cycle instructional activity, students calculate how much water leaves produce from a whole tree. ...
Curated OER
Density - To Float or Not to Float? That is the Question!
Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.
Teach Engineering
Surface Tension Lab
What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...
Curated OER
Plant Structure
In this plant science worksheet, students complete a crossword puzzle with 48 questions. They identify the different parts of a plant.
Curated OER
Do You See What I See?
Students engage in a lesson that differentiates between right and wrong types of observations. In order to conduct the experiment they are provided with leaves and nameless objects with different designs. The two are compared and...
Curated OER
Line: a Geometric Exercise
Pupils study the different types of lines and create a drawing demonstrating what they learned.
Curated OER
Geometry and Tony Smith Sculpture
Students respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label for...
