In this geometry worksheet, 10th graders determine the answer to a vocabulary questions and then follow the give rules to place the answer in the appropriate place on the crossword grid.   The one page worksheet contains 18...

In this geometry worksheet, students differentiate between perpendicular and parallel planes and lines. They identify segments that are parallel and perpendicular to sides. There are  22 questions.

Students discover which regular polygons can be used to tile a plane.

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students investigate geo-profiling.  In this secondary mathematics lesson, students use geo-profiling to determine the most probable location of a criminal.  Students find the centroid of a polygon where the vertices represent...

In this measurement lesson, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.

For this perimeter and area worksheet, students find the perimeter and area of regular polygons. They identify the perimeter and area of polygons such as triangles, trapezoids, circles, rectangles, and parallelograms. Students write the...

Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.

In this math worksheet, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

Students identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.

Learners explore the concept of polygons on a two-dimensional plane. They identify polygons in everyday life and draw different polygons according to their classification. Using a geoboard and geobands, they consrtuct polygons and even...

Define and review math vocabulary. Use the CEENBoT to draw pictures that represent each vocabulary word. Pupils work in groups to play math pictionary.

Fifth graders work with polygons.

Learners explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. Learners place dots on the screen to recognize that they have created Sierpinski's Triangle.

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...

Ninth graders investigate quadrilaterals.  In this geometry lesson, 9th graders examine and classify quadrilaterals using the slope, midpoint and distance formulas.  Additionally, students create various quadrilaterals given...

Students investigate nets as they relate to volume and area. In this geometry lesson plan, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...

Tenth graders explore congruent triangles.  In this geometry lesson, 10th graders investigate the conditions necessary to prove two triangles congruent.  The lesson combines dry erase board activities and the use of technology.

First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Third graders engage in a instructional activity that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while...
