Students explore points, lines and planes as it relates to geometry. In this geometry lesson, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Young scholars compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry...

Fifth graders classify triangles. In this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Students look at the geometry in an artwork. For this art history/geometry lesson, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines, angles, and...

Learners identify clues that tell them about where, when, who and what they are seeing in art images. They work, step by step, through the layers of meaning, delving more deeply into these layers with each work as they progress through...

Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle lesson, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson gives students a meaningful way to practice these...

Fifth graders use the Internet to learn about translations, reflections and rotations. Students access the Transmographer program on the Internet, where they practice what they have learned. Students also complete a worksheet.

Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Fourth graders explore polygons. For this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

Students create a mini city using proportions that fit a model human they construct using tin foil. They plan the city including a library, sports arena, living spaces, parks and businesses. When constructing the paper buildings, they...

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Students take a sample of fish and try to determine how many fish are in the sea.  In this scientific sampling lesson, students explore the way scientists measure large areas of samples. Students record the distribution in a quadrant.

Students stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.

Students examine the idea of "regularity" as it pertains to geometry.  In this geometry lesson students complete several assignments that are part of trihedral angles and regular polyhedrons.

In this math worksheet, students work at home with a family member to identify triangles and find the areas. Students find 3 triangles in tile patterns, wallpaper, paintings or anywhere in the home and answer 6 questions.

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

In this congruency activity, students find congruency in everyday packaging on everyday items and answer questions about them. Students answer 4 questions.

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Students investigate visual arts by researching art on the Internet. In this expressionism lesson, students identify several famous artworks on-line based on self expression and discuss the techniques. Students examine steel sculptures...

Students develop an appreciation for complex structures in nature. They observe patterns in nature in relationship to the Real World. Students use observation skills to assist in problem solving. They show comprehension of the concepts...

Students differentiate between ellipse and hyperbola. For this algebra lesson, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Students review types of polygons and list several examples of each. They assume the role of a landscape artist interviewing for a job. They create sketches of their plans for six polygonal gardens and write an expository paragraph...
