Students create tessellations. In this geometry lesson, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.

Students calculate the are of regular polygons. In this geometry lesson, students create polygons on the computer and move it around to create different shapes. They explore the area of different polygons and how they inter-relate.

Students select a method of presenting on a given topic by rolling paper dice which have various presentation methods on them. They produce the activity and share it with the class.

Pupils play the "space-breaker" game, in which they are required to create a picture using shapes or lines called out to them) to reinforce the concept of geometric shape and line.

Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...

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...

Eighth graders review adding and subtracting of integers. The class makes a number line from -10 to 10 and practice adding and subtracting by "acting out" the math problems. Students play a card game using the number cards from a regular...

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

Students create a picture of an actual scene or overlap the called out lines or shapes into a space-breaker. If someone calls out a line or shape a student had not planned to use in the art, they have to figure out some way to use it...

Students use the Internet to complete a webquest about the terrorist attacks on September 11th, 2001. They complete a worksheet with the researched information.

A site that captures the heartfelt reactions, eyewitness accounts, and diverse opinions of Americans and others in the months that followed the terrorist attacks on the World Trade Center, the Pentagon, and United Airlines Flight 93.

This U.S. Supreme Court case allowed the publication of the "Pentagon Papers." The OYEZ resource provides an abstract containing a concise summary, an audio file, a link to the full text of the decision and a record of how the justices...

Victims of the tragic events of September 11th, Pentagon, World Trade Center, and United Flight 93 Pennsylvania, are listed and remembered in this special project.

A year after the attacks on the World Trade Center and the Pentagon, PBS FRONTLINE explores what America saw on September 11th. For many people, the most difficult questions that remain are not about politics, military strategy, or...
