Students discover the ratio between their heights and the lengths of their intestines. This activity is a good introduction to using lists to find the mean and performing operations on lists. Students then describe and generalize these patterns verbally, symbolically, and graphically. Students learn about patterning and writing simple rules as they explore a hypothetical situation about Martians. Students use ordered pairs to reproduce a picture of a dolphin on the TI-73 screen, and then set up an appropriate viewing window.
Students collect data from a dripping faucet.
Afterwards, they view the same data using a table, a graph, and the trace feature. Students collect data and examine variables that may cause a change in the distance a toy car will travel on the floor when it is rolled down a ramp. Students investigate the results of tossing 5 coins. They compare what happens to what is expected to happen. In this real-world activity, students comparison shop in their community.
