Linear Measure

Activity Name	Activity Description
Perimeter Explorer	Students are shown shapes on a grid after setting the area and asked to calculate perimeters of the shapes.
The Tortoise and Hare Race	Students step through the 'tortoise and hare' race in a short investigation of Zeno's paradox. Discussion can focus on the use of significant digits in linear measure.
Cantor's Comb	Students input a fractional parameter and view the geometric fractal patterns generated by repeatedly erasing the central portion of a line segment.
Shape Explorer	The applet creates an irregular shape on a grid. Students determine area and perimeter of the given shape and check their answers with input to the applet. Discussion should focus on the difference between linear measures (perimeter) and surface measures (area).
