An interactive applet and associated web page that show the properties of a circumcircle of a polygon. The applet shows a regular polygon where the user can drag the vertices to reshape it and alter the number of sides. As the polygon is being varied, the circumcircle is shown, passing through all vertices. The text describes two ways to calculate the radius of the circumcircle, depending on what you are given to start. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the circumference of a circle. The applet shows a circle with a radius line. The radius endpoints are draggable and the circle is resized accordingly. The formula relating radius to circumference is updated continually as you drag. Introduces the idea of Pi. The formula can be hidden for class discussion and estimation. See also the entries for circumference and diameter. See also entries for radius and diameter. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that show the definition and properties of the bounding box of a polygon or set of points. The bounding box is used in other entries to find area using the so-called box method. The grid, coordinates and calculations can be turned on and off for class problem solving. The applet can be printed in the state it appears on the screen to make handouts. The web page has a full definition of a bounding box when the coordinates of the points defining it are known, and has links to other pages relating to coordinate geometry and a worked example. Applet can be enlarged to full screen size for use with a classroom projector.

MIT has developed Climate Science, Risk & Solutions, an interactive online textbook on climate change. It features clear navigation, extensive content, and engaging elements such as read-aloud sections, interactive graphs, and quizzes. Divided into sections like Climate Science, Change, Risk, and Solutions, it includes a glossary with hover-over definitions, additional resources, and a FAQ section. Users can also download the content as a PDF.

Note -
If the dense text is challenging, consider using audio alongside the written sections for easier comprehension. Focus on the interactive parts and quizzes if you're unable to cover the entire site, maximizing engagement with the most interactive features.

The College and Career Competency Framework, developed by Drs. Gaumer Erickson and Noonan, supports educators in systematically embedding intrapersonal, interpersonal, and cognitive competencies into course content. In this way, educators support students to develop into career-equipped, lifelong learners who are socially and emotionally engaged. The College and Career Competency Wheel includes 26 specific competencies categorized in three domains. Each competency is integral to in-school and post-secondary success, as determined by current and emerging research.

This site includes free, research-based instructional resources for all 26 competencies, as well as professional development opportunities to systematically teach competencies and academic learning standards simultaneously, thereby improving academic achievement, engagement, and post-school outcomes.

An interactive applet and associated web page that demonstrate the concept of collinear points. Four draggable points are shown. Dragging any one of them will cause the others to move so they are always collinear. A button controls the line that can be drawn through them. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the concept of complementary angles (angles that add to 90 degrees). The applet shows two angles. You can drag the endpoints of each angle and the other angle changes so that they always add to 90 degrees. They are drawn in such a way that it is visually obvious that together they form a right angle, although they are separate on the page. The angle measure readouts can be turned off for class discussions. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the concept of a concave polygon - one where at least one interior angle is greater than 180 degrees. The applet shows an irregular polygon initially with one interior angle greater than 180 degrees. The user can drag any vertex and change the number of sides in the range 3..99. When the polygon is concave, the angles that make it so are drawn in red. The goal is to show through experimentation what the concept of concavity really means. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the concept of concentricity. The applet shows two resizeable concentric circles and the common center point. As they are dragged to resize, they remain concentric. Applet can be enlarged to full screen size for use with a classroom projector.
