Texas Instruments: At a Snail's Pace for the Ti 73 Explorer
It is hard to imagine a way to mathematically describe a spiral. Spirals are commonly seen in nature. There are a number of different types of spirals. Some interesting examples include the spiral arrangements of scales in pine cones,...

Alex: How Long Will It Take?
In this lesson, students will participate in a group activity using a sponge ball and a growing human circle. The students will be added to a circle in groups of two and will pass the sponge ball from hand to hand until it returns to the...
