Quadrilateral Teacher Resources

In this geometry worksheet, students distinguish which of eight shapes are squares, rectangles and/or triangles. Students write the name of each shape on the lines provided.

In this trapezoids instructional activity, 10th graders solve 5 different problems related to trapezoids and applying the appropriate theorem. First, they define a trapezoid, including its bases, legs, and base angles. Then, students use...

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

For this geometry worksheet, students solve problems dealing with polygons. They differentiate between similar and congruent polygons. There are 18 questions with an answer key.

Students use wax paper to look at different properties of circles such as chords, tangent lines, inscribed angles, and inscribed angles in a semi-circle, as well as finding the center of the circle, and use GSP to investigate cyclic...

Middle schoolers investigate the concept of tessellations and how they are formed using angles. They categorize how different patterns do and not tessellate and separate them into two different places for assessment. The teacher draws...

Pupils expand their knowledge of quadrilaterals and identify basic symmetrical forms. Over three weeks, they explore the math, application, and discussion of symmetry. After conducting Internet research, students create symmetrical...

Learners discover and apply the formula for the area and perimeter of rectangles and squares. They draw the shapes on graph paper and create tables that include their information.

Students investigate tips for calculating math problems mentally.

Students explain the formula for finding the area of a paralellogram and its relation to the area of a rectangle. Finally, they construct the formula for the area of a paralellogram.

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

Twelfth graders apply perimeter measurement to items found in newspapers and calculate the cost in terms of feet or yards. They share answers and explanations with classmates.

Students listen to the teacher read "A Dreamer's Cloak." They examine the difference between squares and circles and create their own cloak by using a paper bag and different shapes.

Pupils, in groups, venture onto the schoolground on a scavenger hunt for shapes. They are given tasks: recorder, team leader, presenter, reporter, and behavior guidelines and a time limit. They search the school for shapes found in real...

Young scholars are given patterns of trapezoids and are to calculate the area of one trapezoid by using both patterns. They should form a parallelogram and calculate the area. They practice this technique until there is understanding.

Students work with given formulas to solve for specific variables. The calculation of the volume of a cylinder and the change in volume when there is a constant surface area is analyzed in this lesson.

Students review basic shapes, such as circles, squares, triangles, and rectangles, find objects in those shapes in classroom, watch Clifford's Fun with Shapes video, practice reproducing four shapes, and rotate through four classroom...

Seventh graders review the concept of finding the areas of a rectangle. This lesson uses the classroom as a real life application for the formula of area. They measure classroom in order to compute the area.

Fifth graders practice fraction skills by making quilts using paper or cloth for the squares and rectangles. Each square of the quilt is an equivalent fraction which they design. Students can also use this activity to demonstrate how to...

Students investigate squares. They generate patterns from structured situations and find a rule for the general term and express it using words and symbols. Students generate patterns from a rule and substitute values and formulas.

Fourth graders investigate the relationships between the area and perimeters of squares and rectangles. They calculate the perimeter of rectangles and squares using a formula. Students investigate the relationship between the perimeter...

Fourth graders explore how to find the area of a rectangular object. As a class, they discuss definition of area and strategies for finding area. The teacher models finding the area of an object by counting squares. Students observe...

Twelfth graders are able to deduce the area of polygons by using several methods such as coordinate method. They are able to apply the area of polygons to real life situations. Students apply the Pythagorean Theorem in problem solving...

Eighth graders practice calculating the perimeter of different shapes. As a class, they work together to calculate the area of rectangles and triangles using the proper formula. To end the lesson, they determine how many feet are in a...
