Does Sunlight Effect Leaf Size?
Young scholars make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in...
Curated OER
Triangle Explorer
Students compute the area of triangles in a computer program. In this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.
Curated OER
Unit Perimeters and Areas
Learners use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson plan, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are...
Curated OER
Elements of Art
Third graders discover elements in visual art. In this visual art lesson plan, 3rd graders explore the use of line, shape, and color in visual art. After reviewing works of art, students create unique art pieces. Technology resources...
Curated OER
Cut It Out
Sixth graders derive an original formula for calculating the area of an irregular figure.

A Galactic Fact Sheet
In this galactic fact worksheet, students read through important facts about galaxies, their shapes, and distances from the Sun.
Curated OER
Perimeter
Students explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.
Curated OER
Hickory Dickory Dock
Learners follow written directions to construct their own tangram. In this tangram lesson, students use their tangram to develop original figures that illustrate characters and/or objects from their favorite nursery rhyme. Learners also...
Curated OER
Perimeter
Students use their hands, feet, computer, and rulers to measure the perimeter of objects. In this measurement lesson plan, students measure objects around the room and computer generated shapes.
Curated OER
Shape Toss
Learners get a bounce ball and find a Polyspot. On the teacher's signal, students underhand throw to a target. They keep their own score: one point each time they hit a target.
Curated OER
Polygons, Pingos, and Themokarst! Oh MY!
Young scholars complete activities to learn about the common land features in Alaska. In this land study lesson, students study an overhead for permafrost features. Young scholars define ice wedge polygons, thermokarst, and pingos....
Curated OER
Geometry Scavenger Hunt
Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
Pennsylvania Department of Education
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
The Good, The Bad, The Ugly
Sixth graders examine the causes of the stock market crash of 1929. For 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...

Which container holds a larger amount of popcorn?
What does popcorn have to do with math? Seventh grade mathematicians are provided an opportunity to develop a conceptual understanding of the formula for volume and to use it as a tool to solve problems. The instructional activity...
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
Orbital path of Landsat
Students comprehend how Landsat satellites orbit teh Earth to produce images. They comprehend the elliptical path of satellites. Students recognize that a different orbital path is needed for different satellites to perform their tasks....
Curated OER
Let's Tesselate
Learners investigate the geometrical concepts of translation, reflection, and rotation. They make different observations looking for the concepts that are displayed in classroom items like floor tiles, carpet designs, and visuals hung in...
Curated OER
Estimation
Students complete computer activities about estimating if items are more or less than a given amount. In this estimation lesson plan, students also estimate measurements around the classroom.
Curated OER
The Estimation Station
Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.
Curated OER
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.
Curated OER
Introduction to Estimation and Making Arrays
Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.
