Pupils explore the concept of trapezoids.  In this trapezoids instructional activity, students identify legs and bases of a trapezoid.  Pupils discuss the similarities and differences between isosceles trapezoids and right...

In this tangram learning exercise, students trace the tangram pieces and cut them out to solve the five problems. Students make shapes with the tangram pieces.

Shape one's understanding of geometry using the resource. The sixth of seven chapters in 6th Grade Math focuses on geometry principles. Future mathematicians learn to find the area of parallelograms, trapezoids, triangles, and other...

Scholars play against three other participants to show what they know about geometric figures. Starting at the beginning, kangaroos jump from shape to shape to match the figure to the displayed word and make their way to the finish...

Swimming pools are no fun without water. For a pool in the shape of a trapezoidal prism, scholars first calculate the amount of water needed to fill the pool. They use experimental data on water flow to determine whether to haul water...

Prepare for the zombie apocalypse ... by studying quadrilaterals? Given a map of an imaginary town, scholars identify quadrilaterals created by streets. They then use Google Earth and Google Maps to find parallelograms, rectangles,...

Face the vertex of two-dimensional shapes and discover what each figure requires as part of its classification. With one shape per slide, learners see what makes each shape special and compare it to others with similar qualities. 

Many things in life take the shape of a polynomial curve. Learners design a polynomial function to model a riverbed. Using different strategies, they find the flow rate through the river.

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...

Put the tree back in geometry! Explore shapes and celebrate Christmas while using pentagon, square, and triangle pattern blocks to create a Christmas tree.

Students explore differents types of triangles and quadriaterals. For this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

In this geometry skills worksheet, students solve 4 problems that require them to calculate the area of parallelograms and trapezoids.

Seventh graders practice finding the area and perimeter of polygons. In this polygon area lesson plan, 7th graders brainstorm shapes and take a walk to locate shapes. Students record properties of shapes and use various shapes to...

In this math worksheet, students find the areas for the shapes. They apply the appropriate formula for each shape that is drawn and in the word problems.

Fourth graders use polygons to create animal figures with symmetry. In this polygons and symmetry lesson plan, 4th graders create a symmetrical animal collage by cutting and gluing geometric shapes and figures from math...

Students observe how certain geometric shapes can be used to make some structures rigid and others flexible. The activity involves construction of a 30-60 right triangle, folding while following directions, and identifying polygons.

Students create identify properties of trapezoids. In this geometry instructional activity, students calculate the area of given trapezoids and review the area formula for parallelograms. They draw a correlation between the area of a...

Students explore a variety of geometric shapes, name them, and list their characteristics. The shapes are transposed into structures and checked for accuracy.

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

In this perimeter and area worksheet, 10th graders solve 12 different problems related to perimeter and area of various shapes. First, they determine the area of a parallelogram with a particular base and height. Then, students determine...

In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Students find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the...

Third graders discover geometric shapes by completing a series of games and activities. Using ropes with knots tied every foot, they make shapes such as squares, triangles, and hexagons. In pairs, 3rd graders use pattern blocks to...

In this area worksheet, 10th graders solve 7 various types of problems by finding the area of various shapes in geometry. First, they determine what happens to the area and perimeter of a rectangle when the length and width are doubled....

Second graders examine two-dimensional shapes using their characteristics. In this shapes lesson, 2nd graders identify similarities and differences by using cut out shapes, diagrams, mirrors, and graphic organizers.
