Fourth graders create and construct a fabric quilt symbolizing the heritage of the Wisconsin community of Cashton. They research Wisconsin historical symbols and use math skills to calculate the number and sizes of the quilt squares. ...

Students talk about the types of insects that you might see if you looked in the garden. They then brainstorm for ideas about how to solve the problem, sort objects into categories and display the results and count the objects in a...

Students explore ratios and their relationships to fractions. They explain the process of identifying ratios and describe their comparison. Students write ratios as fractions and by using colons. They convert the ratios to percents.

Fourth graders construct squares and rectanges in order to help them find areas and perimeters. They gain an understanding of area and perimeter through teacher modeling and then they construct squares and rectangles.

Students learn the difference between perimeter and area by watching a video and a hands on activity.

Learners predict the speeds of humans and hermit crabs and investigate their predictions using ratios and formulas. AppleWorks is used for this lesson plan, which includes a data worksheet.

Students use four different computer estimation applets with several classroom estimation activities.

Fourth graders find the area and perimeters of squares and rectangles using a calculator to check their multiplication. They use the appropriate formulas to find the area and perimeter of the given geometric shapes.

Students work in groups that are engaged in different activities at different times. They watch the video "Madagascar" and collect data pertaining to the Fish Eagle's arm spam. They work together to perform mathematical computations...

In this triangle worksheet, students draw the type of triangles described, 4 total. Space is provided for student's drawings. A reference web site is given for additional activities.

Fourth graders, acting as foresters, determine timber volumes as sawtimber or pulpwood for marketing. They find the marketable value of a tree using its diameter and volume.

Learners calculate the area of triangles using a variety of materials including computer applets.

Students label objects in their classroom based on mass and volume using the metric system. They examine the relationship between the numerical value and the corresponding metric unit.

Learners figure out and discuss the irony of this coin-centric poem. They also practice persuasive letter writing, and identify and count coin/money values.

Students read and relate the poem, "Clouds" by Aileen Fisher to a demonstration on cloud formation. They create clouds in jars using ice water and matches then discuss the ways clouds can be used to predict weather.

Students investigate geometric shapes in their environment, make a geometric design, and write paragraphs describing the design.

Students identify, describe, count, tally, and graph life found in one square foot of land.

Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

In this area and perimeter worksheet, students complete a set of 6 problems, finding area of rectangles and area and perimeter of squares. 

Students identify the sources of pollution and waste in their community. They examine the process of recycling and how to eliminate some of their family waste.

Fourth graders are introduced to the problem by weighing objects on the balance scales. Use weights in both pans. (If you don't have access to scales use 2 containers and a child acting as the balance.) They then listen to the problem...

Students develop a graphic way of visualizing the concept of a million by utilizing what had happened to the Nashua River due to the dumping of raw sewage in 1962.

Students work in pairs, first doubling each number with pencil and paper, and checking it with a calculator.

Students discuss the directions on a package of seeds. They open the package, count the seeds, and determine the planting requirements for the seeds.
