Amazing Transpiration
Learners observe a leaf and discuss the way that water is released from a leaf through its stomata. For this water cycle lesson, students calculate how much water leaves produce from a whole tree.
Curated OER
Does Sunlight Effect Leaf Size?
Students 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 constant...
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
Students use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry instructional activity, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets...

Unit 6 Math Vocabulary Cards (Grade 5)
Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...
Curated OER
Cut It Out
Sixth graders derive an original formula for calculating the area of an irregular figure.
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
Students follow written directions to construct their own tangram. In this tangram instructional activity, students use their tangram to develop original figures that illustrate characters and/or objects from their favorite nursery...
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
Polygons, Pingos, and Themokarst! Oh MY!
Students complete activities to learn about the common land features in Alaska. In this land study instructional activity, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos....
Curated OER
Geometry Scavenger Hunt
Young scholars 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. 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 finished...

How Many Leaves on a Tree? (Version 2)
A second attack at figuring out the number of leaves on a tree, this activity makes both an excellent follow-up to version 1 and a stand-alone activity. Learners practice setting parameters and deciding acceptable estimate precision, and...

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...

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 lesson begins with a...
Curated OER
Let's Tesselate
Students 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
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.
Curated OER
Geometry and Tony Smith Sculpture
Young scholars 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...
Curated OER
What's Your Design?
Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.
