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,...

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

In this geometry worksheet, 10th graders determine the area and perimeters of various quadrilaterals and triangles.  The one page worksheet contains ten problems.  Answers are not provided. 

In this online interactive math skills worksheet, students solve 10 multiple choice math problems regarding geometry skills. Students may view the correct answers.

Seventh graders study geometric shapes around the classroom. In this geometry lesson plan, 7th graders discuss their answers in groups to the Anticipation/Reaction guide handout. Students complete the reaction side of the guide and...

Everyone knows that opposite sides of a parallelogram are congruent, but can you prove it? Challenge pupils to use triangle congruence to prove properties of quadrilaterals. Learners complete formal two-column proofs before moving on to...

Combine math and language arts in the same lesson with a reading passage about number prefixes in geometric shapes. After reading several short paragraphs about the different prefixes used in shape names, kids answer five comprehension...

Scholars explore parallelograms in this geometry lesson. They investigate the properties of a parallelogram. Assisted by technology, your learners will construct a parallelogram and examine the sides, angles, and diagonals to discover...

Students identify geometric patterns in quilts. In this geometry lesson plan, students view various types of quilts and identify the geometric shapes. Students construct one hundred patch paper quilts using geometric shapes.

Students take an Internet field trip to research fractions. ESOL strategies include using pattern block manipulatives and pairing ESOL and non-ESOL students on computers.

Middle and high schoolers explore the concept of proving the Pythagorean Theorem. They research proofs of the Pythagorean Theorem. Pupils create posters of proofs, and research Greek mathematicians.

What shape do I see? Pupils will use what they know about geometric figures to determine which shape is hidden behind the squares. The shapes identified in the game: square, triangle, hexagon, and decagon. This is a great warm-up activity.

In this conditional statement learning exercise, students read statements and identify the inverse of the statement.  They write conditional statements based upon given criteria.  This two-page learning exercise contains 5...

High schoolers discover properties of parallelograms as they construct a parallelogram using Cabri Jr. They will measure angles and side lengths of their construction and determine the relationship between the diagonals of a...

Students measure prisms and determine their volume. In this measurement and reasoning lesson, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders. They determine...

Students calculate area, perimeter and length of rectangles. In this geometry lesson, students create different formulas for the problem they are being asked to solve. They use the navigator to move the shape around and make observations.

In this geometry worksheet, 2nd graders trace the squares on the left and draw a line to connect the ones that are the same size on the right.

In this perimeter worksheet, 10th graders solve and complete nineteen various geometry problems. First, they find the length of given segments in addition to the perimeter of a kite. Then, students find the value of a variable so that...

In this geometry and shapes worksheet, 5th graders practice calculating the shaded area of 2 objects. Students count the squares on 2 grids to find the volume of each object in cube units.

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

In this geometry worksheet, students describe the effect of a proportional change on the perimeter or circumference and area of the given circles or quadrilaterals.  The one page worksheet contains ten problems.  Answers are...

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...

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

Students identify polygons.  In this geometric shape instructional activity, students explore the characteristics of polygons.  They identify polygons, and classify triangles according to their sides and angles.  Students...
