Students will create a map that includes (at minimum) five buildings, one must be your house and one must be the post office. They will use the spheros to find the best route to the post office in order to ship their gift, in the shortest amount of time. Students will need to find the length and width of each building on your map, using the spheros and the distance=rate x time and find the area of each building.

This is an introductory project-based lesson. It is assumed that background knowledge of vocabulary, procedural steps, and concept have been previously instructed. In this project, students will create a square-based pyramid net that would represent their actual tent. Then, they will need to figure out how much fabric that they will need in order to cover their tent. Extensions are built into this activity that would allow the students to practice / explore skills with decimals, percents, and ratios.

In this project, students will create videos that describe what surface area is, what algorithmic steps are needed to find surface area, and finally, they will show how to find the surface area of a polyhedron. Note: This lesson assumes that students have had previous lessons on surface area. This lesson is meant to be sort of a summative assessment tool in which students show their conceptual and procedural fluency of surface area.

A web page and interactive applet showing the ways to calculate the area of a parallelogram. The user can drag the vertices of the parallelogram and the other points change automatically to ensure it remains a parallelogram. A grid inside the shape allows students to estimate the area visually, then check against the actual computed area, which is continuously recomputed and displayed. The text on the page gives three different ways to calculate the area with a formula for each. The applet uses one of the methods to compute the area in real time, so it changes as the rhombus is reshaped with the mouse. A companion page is http://www.mathopenref.com/parallelogram.html showing the definition and properties of a parallelogram 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 explain the area of a triangle. The applet shows a triangle that can be reshaped by dragging any vertex. As it changes, the area is continually recalculated using the 'half base times height' method. The triangle has a fixed square grid in its interior that can be used to visually estimate the area for later correlation with the calculated value. The calculation can be hidden while estimation is in progress. The text page has links to a similar page that uses Heron's Formula to compute the area. 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.

Students are given two vertices of a triangle and its area. They are asked to determine where the third vertex is located. The mathematics task is intended to be a problem or question that encourages the use of mathematical practices. The dialogue is meant to show how students might engage in the mathematical practices as they work on the task.
