#### Rhombus Diagonals

Delving into a proof that the diagonals of a rhombus are perpendicular to each other, this lecture evaluates the angles and sides of this figure. It would serve as a great test preparation activity.

Lesson Planet

#### Properties of Different Quadrilaterals

Properly apply the properties of parallelograms. Pupils answer a set of questions designed to review the categories of quadrilaterals. They then identify the shape in each set of quadrilaterals that does not belong and explain why.

Lesson Planet

#### Quadrilaterals

Connect the quadrilaterals. Working in teams, pupils use a variety of tasks to make connections between special quadrilaterals. With the properties well defined, the groups construct quadrilaterals based on those properties. Learners...

#### Quadrilateral Or Not?

Teach young mathematicians which shapes are classified as quadrilaterals and which aren't. A fun card game engages learners of all levels as they match shapes to the teacher's requests.

Lesson Planet

#### Accessible Shapes

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Lesson Planet

#### Construct a 30 Degree Angle

Split it down the middle. Using the tools of geometric construction, the video shows two different methods of constructing a 30-degree angle. The first method bisects an angle of an equilateral triangle. The second uses the diagonal of a...

#### Area and Perimeter of Rhombuses and Kites: Lesson

Flip the triangles up and create a parallelogram. Using the idea of transformations, the video develops the area formula for rhombi and kites. The segment of an extensive geometry playlist uses the formula to find the areas of different...

Lesson Planet

#### Quadrilateral Quandary

Classify quadrilaterals quickly. After playing a game to identify quadrilaterals, your young scholars should come away with knowledge of the properties of quadrilaterals. They then apply this knowledge to create a decision tree to ease...

Lesson Planet

#### Classifying Parallelograms: Lesson

Properly organize parallelograms. Given special parallelograms, the narrator of a short video explains the properties of each. The section of a playlist on geometry uses the properties to classify the special parallelograms.

Lesson Planet

#### Classifying Quadrilaterals in the Coordinate Plane: Lesson

Coordinate the classification of quadrilaterals. Given the definitions of special quadrilaterals, a portion of a geometry playlist highlights ways to classify a quadrilateral. The video takes information from figures on a coordinate...

Lesson Planet

#### Diagonals to Quadrilaterals

Begin from the inside and work outward. Pupils construct quadrilaterals based upon the descriptions of the diagonals. Pairs then work through several configurations of diagonals and determine the types of quadrilaterals they can form....

Lesson Planet

#### Transformations of Parallelograms and Rhombi

Back to the original figure. Young mathematicians consider transformations that carry figures onto themselves. The figures in question are a parallelogram and a rhombus.

Lesson Planet

#### Building Graduation Caps

Top off geometric calculations by building caps. Groups determine the sizes needed and build each member a mortar board graduation cap. Using the average size, the team calculates the total amount of material required to build a typical...

#### Exploring Quadrilaterals

Sort this resource into the Use pile. Scholars investigate attributes of quadrilaterals and then use the results to sort and classify the shapes labeling each figure with their properties to justify the classifications.

Lesson Planet

#### Quadrilateral Sort

If only you had a Sorting Hat to sort out quadrilaterals. Learners sort cutouts of quadrilaterals based on their properties and attributes. A flowchart helps them organize the results of the activity.
