My artifact this year was teaching a Guided Math unit with my Grade 7 class. I had my students work together with similar abilities to achieve full learning potential. My supports and guidance while doing this unit was other teachers in our school who are already implementing Guided Math in their classroom. Students collaborated well within their groups and were happy with the process and their individual results.

An interactive applet and associated web page that demonstrate opposite rays. The applet shows two rays with a common endpoint and can be dragged with the mouse. If the rays are in a line, the message 'Opposite rays' appears. A detent makes it easier to get them perfectly aligned. Applet can be enlarged to full screen size for use with a classroom projector.

A web page and interactive applet demonstrating the concept of the orthocenter of a triangle. The applet shows a triangle where the user can drag the vertices around. The orthocenter and the altitude lines that generate it are continuously moved as the user drags the vertices. By experimentation the user can observe that the orthocenter can be inside or outside the triangle. The page text explains the definition of the orthocenter and how to find it. Applet can be enlarged to full screen size for use with a classroom projector.

Two besotted rulers must embrace proportional units in order to unite their lands. It takes mathematical reasoning to identify the problem, and solution, when engineers from Queentopia and Kingopolis build a bridge to meet in the middle of the river.
