Use this introductory geometry worksheet as a projected warm-up for your class, doing it together and then revealing the explanation on the bottom half. Learners examine a square and a circle, each bisected by a dotted line. They must...

It's time for a geometry warm up! Geometry scholars examine a figure to determine its name from a list of four choices. The figure, a trapezoid, is large enough for the whole class to see if you were to project this. An explanation at...

Students find the area of polygons.  In 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...

In this properties of geometric shapes worksheet, 4th graders write the words all, some or no to complete twelve statements about the properties of the shapes.

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 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 worksheet, 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 the...

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...

In this geometry learning exercise, 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...

Students 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 examples...

Learners 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...

Students investigate tips for calculating math problems mentally.

Young scholars 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.

Students 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.

Students, 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...

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...

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...
