As a part of our school SWISI program, we work on math skills during our assigned time. For this activity students will be scanning QR codes that align with the unit they are working on in math at the time.

"These three free digital courses introduce students to what data science is and why it matters. Through interactive exercises, students explore foundational data science knowledge, including collecting, visualizing, and understanding data. Data Science Foundations is the 101-course with two extension opportunities in the form of a Financial Wellness and Banking Fraud simulation."
Includes 3 courses:
*foundations
*financial wellness
*banking fraud

A web page and interactive applet illustrating the properties of a decagon (10 sided polygon). The applet shows a decagon where the user can drag any vertex to reshape it. User can see that the interior and exterior angles are constant in a regular decagon, but vary in an irregular version. Controls allow the display or hiding of the diagonals, and triangles within the decagon. The web page lists the properties of a decagon including interior angles, exterior angles, sum of exterior angles, area, number of diagonals and number of internal triangles. Links to pages with generalized properties of all polygons. 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 demonstrate the intersection of two lines. The applet shows two line segments with draggable end points. As the lines are moved, the intersection point id continuously updated. If the two segments do not intersect, a message pops up to that effect. Applet can be enlarged to full screen size for use with a classroom projector.
