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...

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Extend scholars' learning experience with a unit consisting of five shape lesson plans, an extension activity, assessment, and rubric. Begin by reading a story about shapes, then conduct an overview and assign pupils' their first...

The 21st segment in a 28-part series provides learners with area problems involving composite figures. To find the solution, pupils must decide whether to add or subtract areas. The composite figures are composed of quadrilaterals,...

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...

Students compute areas of squares, rectangles, and so on and summarize the formulas for computing areas and explain how the formulas are derived and understand the reasoning behind them.

Sixth graders use different measuring tools to measure area, perimeter, and circumference of different shapes. In this measurement lesson plan, 6th graders measure parallelograms, triangles, and circles.

Learners show the correlation between quadrilaterals, parallelograms, rectangles and squares.

In this tessellations worksheet, 10th graders solve 6 different types of tessellation problems that includes drawing. First, they define polygon, regular polygon, tessellation, regular tessellation, and semi-regular tessellation. Then,...

Sixth graders explore different polygons. In this polygon lesson, 6th graders examine a rhombus, quadrilateral, parallelogram, and rectangles. Students compare and contrast polygons and research shapes on the Internet.

Students use construction technology to identify and find relationships between the attributes of various quadrilaterals. They make and test conjectures about the distinguishing properties of parallelograms, rectangles, rhombuses,...

In this area and perimeter worksheet, students find the length or area of seventeen figures.  The figures examined are triangles, trapezoids, parallelograms, rectangles, and hexagons.  Some examples and solutions are...

Seventh graders complete activities to further their understanding of area formulas. In this area lesson, 7th graders watch as the teacher uses Polystrips to model parallelograms. Students find the area of a rectangle and answer...

In this quadrilateral and angle sum worksheet, students review the five types of quadrilaterals. Students then find each missing angle measure and classify the figures as quadrilateral, parallelogram, rectangle, rhombus, square, or...

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Fourth graders investigate the concept of computing the area using different shapes. They use prior knowledge in order to devise a formula for a parallelogram. Scaffolding is provided by the teacher to find the formula of area for...

Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

In this geometry worksheet, young mathematicians apply the formulas for the area and perimeter of polygons and circles to solve a variety of skills practice and problem-solving questions.

In this perimeter and circumference worksheet, students observe diagrams and determine their perimeter or circumference. Diagrams include triangles, circles, parallelograms, rectangles, and composite figures. This one-page worksheet...

Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...

Students visit various websites to calculate the area of circles, triangles, rectangles, trapezoids, and parallelograms. They explore math problems and play interactive games dealing with geometry.

Challenge math scholars with polygon word problems that require logical reasoning. They answer two word problems about geometric shapes and their arrangement in a column based on clues given. Next, learners draw a robot made of...

Another good presentation by Christine Berg is here for you. In it, learners are coached on definitions of area and perimeter and are shown how to perform calculations for both. They also see how to calculate the area of a triangle by...

Students comprehend how Landsat satellites orbit teh Earth to produce images. They comprehend the elliptical path of satellites. Students recognize that a different orbital path is needed for different satellites to perform their tasks....
