Here is an excellent cross-curricular lesson. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

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...

Seventh graders are introduced to making inferences about artifacts. Using a grid system, they locate the artifacts and determine where they originated from. They use this information to make conclusions about the way people lived...

Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...

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...

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

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...

Math whizzes use the area probability applet to manipulate the size of the circle and the rectangle to explore the probability that a point in the rectangle is also in the circle.

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

Develop a better understanding of the value of pi. Learners explore the area of a circle using estimation and graph paper. While continuing to estimate the area of the circle using smaller and smaller grids, the number pi emerges. 

Learners use grid boxes as a measurement tool and discover how grids are used for mapmaking and scaling down an area. They begin by attempting to draw a model shape drawn by the teacher by using the gridding process. At the conclusion of...

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

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.

Fourth graders estimate the surface area of a pond using the chance method and the estimation method. They complete a graph and a short report comparing the results of the two methods.

Young mathematicians join the ancient order of the Pythagoreans by completing an assessment task that asks them to find the area of tilted squares on dot paper. They then look at patterns in the squares to develop the...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

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.

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. 

Students investigate unit conversion.  For this unit conversion lesson, students will build models of square and cubic centimeters using grid paper and generate formula tables for converting units of area and volume.  The...

Trace Columbus' voyages by locating them on 21st Century maps.  Using a navigators lesson, 4th graders will examine the Age of Exploration and trace Columbus's routes accurately on laminated world maps using different maps. Note:...

Learners establish a grid system over an archaelogical site. They label each grid unit. They determine the location of artifacts within each grid unit. They construct a scientific inquiry concerning the location of artifacts on the site.

Learners calculate the area of different polygons. In this geometry lesson, students explore polygons based in their shape and number of sides. They find the formula for the area and use each specific formula for each shape.

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.
