An interactive applet and associated web page that provide step-by-step instructions on how to find the centroid of a triangle using only a compass and straightedge. The method used involves constructing two of the triangle's medians. The centroid is where they intersect. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

An interactive applet and associated web page that provide step-by-step instructions on how to find a median of a triangle using only a compass and straightedge. The method used involves bisecting one side, then drawing a line from this midpoint to the opposite vertex. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that provide step-by-step instructions on how to construct the orthocenter of a triangle using only a compass and straightedge. The method used involves constructing two altitudes of the triangle, which intersect at the orthocenter. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

Students work in pairs to create three simple types of model bridges (beam, arch, suspension). They observe quantitatively how the bridges work under load and why engineers use different types of bridges for different places. They also get an idea of the parts needed to build bridges, and their functions. The strength of model bridges is mainly a factor of the quality of materials used, and therefore they do not provide a clear visual representation of tension and compression forces involved. Yet, students are able to see these forces at work in three prototype designs and draw conclusions about their dependence on span, width and supporting structures of the bridge designs.

The construction of the perpendicular bisector of a line segment is one of the most common in plane geometry and it is undertaken here. In addition to giving students a chance to work with straightedge and compass, the problem uses triangle congruence both to show that the constructed line is perpendicular to AB and to show that it bisects AB.

Students examine consumer choices and fair trade in this excellent grade 7/8 project. Choices are available for I DO, WE DO and YOU DO.

This form of painting became popular during the Cultural Revolution in China (1966-1976). Images depicting people's every day lives became a natural focus under the regime of Chairman Mao. Artists in places like Hu County in Shaanxi Province (near Xi'an), where these painting were made, were discovered and became popular. This particular series of Peasant Paintings, by a mature, female artist named Dong, were done in a studio production method.The peasant paintings depict festivals and daily routines: preparing food, doing laundry, traditional parades (lanterns, dragons), animals and fish. Some tell stories with symbolism. This curriculum resource will provide potential lesson topics and areas of discovery and a set of images for teachers of art, Chinese culture & history at elementary, middle and high school levels. The paintings may serve as supplementary visuals for K-8 teachers of science, and geography.

This assignment is based on an integration of current events with an examination of indigenous cultures in North America. There are two final products involved – a presentation and a fullclass discussion.

Students will examine Rembrandt's "Abduction of Europa" and discuss how the artist has taken an ancient Greek myth and contemporized it for a 17th-century Dutch audience. They will then read origin myths and choose a scene to illustrate in a contemporary setting.

Dr. Royce observes a lesson on water evaporation in Ms. Maronpots class, gives her feedback, and visits again one week later. See the changes Ms. M makes in her lesson before and after the visit.

Teachers are required to implement the adopted content standards and to make the connection between standards-based curriculum and the planning and designing of lessons to ensure that students meet expected content standards. This Module serves as a basic guide for the process (est. completion time: 2.5 hours).

Chandra Garcia uses continent-shaped puzzle pieces to teach her students about continental drift. Working in small groups and using fossil evidence, students must work cooperatively and find consensus among themselves to build their arguments.

Continents/Oceans Quiz
Students will match the names of the continents and oceans to the letters on the map

Drag the proper label to the continent or ocean while the globe spins by.

Students use the robot paths they documented during the associated Robots on Ice Engineering Challenge activity to learn about and then make artwork. During the previous activity, students recorded the path of their robots through a maze in order to collect data during a remote research simulation. Now, they take a new look at the robot paths, seeing them from an art perspective as continuous line drawings. Students learn about Picasso’s famous works of art that used the same technique. Then they learn the artistic definition of a line and see examples of how it is used in different art pieces; they practice making continuous line drawings and then create sculptures of their drawings using colorful wire. A PowerPoint® presentation is provided to guide the activity.

Students will focus on how one artist tells the story of Joseph using continuous narrative. By observing and discussing visual details such as color and movement found in the painting, students write about what they think is happening. Students are encouraged to use the actions they observed in the painting to create and write a new story with a new character, and then illustrate them in their own continuous narrative.

This amazing video will clearly explain the PeBL philosophy at Sun West School Division. The who, what, when, where, why and how of PeBL are addressed and articluated clearly for the parent and community audience. Topics include the continuum of learning, transfer of responsibility, personalized learning, the three pillars of PeBL. This resource will clearly explain everything you need to know to get started embracing PeBL at home!

This graphic addresses the considerations (where, when, who, how, what and why) of PeBL, as well as the learning environment and the transfer of responsibility.
