Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

Students analyze characteristics of various 2 dimensional shapes and explore their properties and use various vocabulary terms to discuss geometric relationships.

Students, in groups, estimate measurments and then select the tools needed and measure various items at Black Bayou Lake refuge.

For this math worksheet, students find the solutions to the eighteen problems while substituting the numbers for the variables in the expressions.

Students explore different types of quadrilaterals. Students define the terminology used with quadrilaterals. They create particular quadrilaterals based on specific characteristics of the quadrilaterals using an online tool.

In this math worksheet, students look for the properties related to each shape and then fill in the graphic organizer with the categories needed.

Students are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.

Third graders represent fractions as part of a whole. In this fractions lesson plan, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson plan includes individual practice and an assessment instead of...

Young scholars create their own Chinese tangrams using in-class direction and prior knowledge in this two-day lesson for the early elementary classroom. Chinese toys are also explored.

These activities provide an opportunity for students to explore the area formulas for triangles, trapezoids, and parallelograms.

Resource examines the area of geometric solids through examples and a video lesson. [0:39]

To find the area of a triangle, try to make a parallelogram using a copy of the triangle.

Demonstrates how to calculate the area of two-dimensional shapes using formulas. Covers parallelogram, triangle, trapezoid, and circle. Includes a video modeling how to find the area of a circle and a triangle. [0:59]

Students review the definition and area formula for the rectangle, square, parallelogram, triangle, trapezoid, and circle.

Try to figure out the area of this challenging shape. In order to view the images, you will need to use JavaSketchpad.

This lesson presents the idea that the area of any triangle is exactly half of a certain parallelogram -- thus we get the familiar formula of multiplying the base and the altitude and taking half of that. The lesson contains varied...

Students solve for the area of rectangles, squares, triangles, trapezoids, and parallelograms.

[Free Registration/Login may be required to access all resource tools.] This study guide looks at the definitions and units for perimeter, area, and circumference, and at the perimeter and area of different shapes, including regular...

Given composite figures (combinations of rectangles, squares, parallelograms, trapezoids, triangles, semicircles, and quarter circles), students will be able to determine expressions for the area as well as calculate the area of the figure.

Given information about composite fiugres, the student will determine the area of composite 2-dimensional figures comprised of a combination of triangles and parallelograms using appropriate units of measure.

Sixth graders find the area of rectangles, triangles, parallelograms, and trapezoids by using formulas or by composing into rectangles or triangles.

[Free Registration/Login may be required to access all resource tools.] This study guide reviews the formulas for area and perimeter of triangles and different kinds of quadrilaterals.

Calculate the Area of a Trapezoid This Concept Handheld Software Application reviews the definition and area formula for the rectangle, square, parallelogram, triangle, trapezoid, and circle.

Students will find the area of a parallelogram and the area of a triangle.
