[Free Registration/Login may be required to access all resource tools.] This concept teaches students the properties of rhombuses, rectangles, and squares.

Examines special parallelograms. Students learn about a rectangle, rhombus, and square. Definitions and examples with solutions are included.

This activity allows the teacher to cover the properties of a parallelogram, rectangle, rhombus, square, kite, and trapezoid in two days (90 min. block scheduling) Using a group setting students discover these properties using the Cabri...

In this activity, students will study special types of parallelograms like rhombus and rectangle, and investigate properties related to their diagonals.

This lesson presents the idea that the area of any right triangle is exactly half of a certain rectangle, and contains varied exercises for students.

This tutorial provides a brief introduction about what area is, then gives the formulas for area of a square, rectangle, parallelogram, trapezoid, triangle, and circle. Examples of each formula are provided.

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

Students are taught how to calculate the perimeter of a parallelogram. Extra practice drill problems are also included.

Calculate certain variables of a parallelogram depending on the inputs provided. Calculations include side lengths, corner angles, diagonals, height, perimeter, and area of parallelograms.

A complete reference guide to quadrilaterals including squares, rectangles, parallelograms, trapezoids, and rhombus. It provides definitions and interactive activities that enhance further explanation.

A thorough look at the extensive uses of geoboards in the classroom. Links are listed which give introductory information on geoboards - for teachers new to using them. Then, lesson plans are provided for using geoboards in teaching...

[Free Registration/Login Required] In this flipchart, students will investigate the area and perimeter of rectangles and parallelograms. This is an interactive lesson and also includes an assessment.

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

Practice using your graphing calculator for constructing a parallelogram, a rhombus, a kite, a trapezoid, an isosceles trapezoid, a rectangle, and a square. If you get stumped or if you would like to check your work, then select the View...

Quadrilaterals-parallelograms, rectangles, and trapezoids-are thoroughly introduced in this lesson plan for upper elementary and middle school students. Lots of resources are linked to it to help support the teacher and students....

In this lesson plan, students learn how the diagonals of a rhombus are related. They use interactive sketches to learn about the properties of the angles and diagonals of squares, rectangles, rhombuses, parallelograms, and other...

This lesson plan helps students explore the mathematical concept of area and features resource links to further learning. CCSS.Math.Content.3.MD.C.7.a Find the area of a rectangle with whole-number side lengths by tiling it

At early stages of understanding of geometric shapes, 4th graders describe shapes, but do not yet characterize shapes by their properties. One example of a misconception students have at this stage is that a rectangle has two short sides...

Are you looking for a very basic website that will explain the basic properties of a quadrilateral? Use this site to learn about the properties of a square, rhombus, rectangle, parallelogram, trapezoid, and kite. There are also some...

Given examples of quadrilaterals and their component parts, the student will use explorations and concrete models to prove a quadrilateral is a parallelogram, rectangle, square, or rhombus using opposite sides, opposite angles, or...

Find the area or perimeter of shapes like triangles, rectangles, parallelograms, and hexagons on the coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[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...
