This multimedia that includes a short video [1:19] and other interactive activities on Learn Alberta math resource looks at real-world examples of shape classification in the investigation and solving of crimes. The accompanying...

Test your knowledge of the sum of angles inside a quadrilateral.

Test your knowledge of identifying quadrilaterals.

Determine quadrilaterals based on parallel sides.

The lesson investigates types of quadrilaterals. Definitions, examples, and a worksheet are available.

Introductory site on polygons, with exercises on the basic ones.

Learn about the properties of rectangles, rhombuses, and squares, and practice identifying them. Includes hints for questions. CCSS.Math.Content.3.G.A.1 Understand that shapes in different categories

Identify squares, rectangles, and rhombuses. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints. CCSS.Math.Content.3.G.A.1 Understand that shapes in different categories

[Free Registration/Login may be required to access all resource tools.] Cursor down if needed to locate the video "Visually Identifying Quadrilaterals (Trapezoids, Parallelograms, Rectangles, Squares, Rhombi)." Students watch a video and...

After reviewing the properties of different quadrilaterals, students answer questions about each type.

[Free Registration/Login may be required to access all resource tools.] For this learning module, students are asked to identify which type of quadrilateral matches the description given. Includes video demonstrating a sample problem...

In this instructional activity on 2D shapes, 3rd graders will learn to discriminate quadrilaterals from other polygons. Additionally, they will be able to identify attributes of a square, rectangle, and rhombus.

Brush up on your math skills relating to the types of quadrilaterals then try some practice problems to test your understanding.

Determine the missing angle measures of quadrilaterals inscribed in circles.

The learning activity asks students to identify quadrilaterals by characteristics rather than appearance. Learners drag the vertices of the shape to reveal the true shape of the quadrilateral. [Requires Java.]

The tutorial examines the different properties of quadrilaterals. The table consists of picture of the shape and a list of the shape's properties.

Guide a mummy safely through the burial chambers of a pyramid as you solve length and area problems in basic to advanced geometry. There are four game zones that deal with circles and triangles, quadrilaterals, the Pythagorean Theorem,...

An interesting technique is used for student viewers to learn about quadrilaterals. A viewer can meet the quadrilateral family by clicking on a link and characters will introduce themselves and tell you about their distinguishing...

Learn about the properties of 2-D shapes: circles, triangles, polygons, and quadrilaterals. Includes information, video, and examples about each, with games and quizzes for reinforcement.

Test your knowledge of the area of quadrilaterals.

In this activity, students use the tools of Cabri Jr to test their knowledge of geometry. They investigate the properties of the shape formed by connecting the midpoints of adjacent sides of a quadrilateral.

Students will be sent ordered pairs through lists using the TI-Navigator. These pairs will then be graphed as a line graph and students will classify the shape of the quadrilateral and justify their choice.

Here is a huge collection of teacher resources for teaching 2-D and 3-D shapes. Includes smartboard and PowerPoint presentations, as well as worksheets and helpful hints.

In this task, students ultimately use the definitions they are given for three types of quadrilaterals and what they know about parallel sides to identify that a square fits all the definitions and explain why. Aligns with 4.G.A.2.
