Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, students apply this new knowledge to...

In this area of shapes unit, upper graders participate in hands-on problem solving activities to find the formulas for the area of a parallelogram, a triangle, and a trapezoid. They manipulate the geoboard to explore relationships among...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Geometric shapes are really cool. Examine triangles, quadrilaterals, trapezoids, rhombuses, parallelograms, pentagons, and hexagons with your class. They draw large shapes and small shapes then compare them to understand their shapely...

Learning how to define vocabulary words related to solving parallelograms will assist your learners in identifying different parallelograms. They use the navigator to view different shapes created by moving the parallelogram around.

Students study geometric shapes and practice naming them properly. In this geometry lesson, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...

Third graders investigate congruent polygons through dance. In this congruency lesson, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

Students classify quadrilaterals, In this quadrilaterals lesson, students watch a video about parallelograms, discuss the different types of quadrilaterals, and complete a worksheet classifying 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.

Students construct a variety of four-sided figures using a K'NEX Geometry Set. They view and discuss pictures of shapes, then in small groups they construct as many four-sided shapes as possible using the K'NEX Rods and Connectors. As a...

Students calculate the area of a parallelogram. In this geometry lesson, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.

Young scholars calculate the area of parallelograms. For this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.

Students learn the basic definitions of a quadrilateral, parallelogram, rectangle and square and explain the relationship/classification process between them.

Young scholars read the book The Math Curse by Jon Scieszka and study geometry. In this geometry lesson, students identify geometric shapes and their properties. Young scholars create a geo-critter.

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Students identify different properties of parallelograms. In this geometry instructional activity, students complete problems that proves the theorems and properties of parallelograms. They graph the different shapes on paper.

Students find the area of polygons.  For this area of polygons lesson, students find the area of parallelograms, rectangles, squares, and other polygons.  They identify each given figure and determine the appropriate formula...

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...

Sixth graders identify and use area formulas for finding the area of geometric shapes.

Third graders use various shapes to identify polygons and understand symmetry. They explore pattern blocks noticing their similarities and differences, then share with other team members. They draw 3 polygons in their journals and...

Use this geometry review worksheet to have learners complete nine problems involving transformations, area, volume, and unit conversions. They answer one multiple choice question on estimating lengths.

Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...
