How many sides does that polygon have? Building directly from lesson number eight in this series, learners now find the area and perimeter of any polygon on the coordinate plane. They decompose the polygons into triangles and use Green's...

Sixth graders design rectangular gardens with a given perimeter and generalize how to maximize the area Students applying the formulas for perimeter and area of polygons. They analyze length, area, and volume and make relationships...

Students solve problems by finding the perimeter and area of an enclosed area. In this geometry lesson, students differentiate between the area and the perimeter. They see how they relate and how to use it to maximize an enclosed area.

Fifth graders demonstrate the concept of perimeter and area using manipulative. In this area and perimeter lesson plan, 5th graders explore area and perimeter through the exploration style of teaching using eatable and non-eatable...

Beginning geometers use tiles and grid paper to draw and calculate perimeter and area. Rectangles of different sizes are created and then measured to build understanding. The one-inch grid sheet referenced is attached. 

Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.

Students use their knowledge of area and perimeter to design a fictitious garden fence. In this area and perimeter lesson, students design a garden fence with a set perimeter. They are given the cost per foot of the fence, and determine...

Students explore area and perimeter through coordinate geometry using student literature, hands-on manipulatives, and the Internet.

Students explore geometry by participating in a school measuring activity. In this perimeter lesson, students discuss the techniques and methods used in order to measure a large perimeter or geometric figure. Students utilize grid paper,...

Third graders create polygons with perimeters of 30 centimeters, use the centimeter grid paper to determine the area of each shape, and organize the shapes to make generalizations from the patterns they see.

Students use M&Ms to simulate radioactive decay of elements.

Learners identify the stages of the water cycle. They listen to the book "Magic School Bus: Wet All Over," examine the Build Your Own Water Cycle website, predict and measure the amount of water in a jar for a week, and read a short play...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Students create a rectangular garden using paper and tiles. In this geometry instructional activity, students investigate the largest possible rectangle that can be created given specific boundaries. They use grid paper to draw the...
