Data in Math

After Winter Break we have moved into a unit in math dealing with data analysis. One of our first lessons was created to help students understand how data can be useful. We pretended we were going to do a fund raiser on making and selling friendship bracelets. We discussed how favorite colors and designs had to be incorporated into our bracelets to be profitable. The size of the average wrist is just as important. Taking an hour of math time, students collected each person's wrist size to the nearest 1/8 inch and then plotted the data on line plots. In analyzing the line plot we were able to find median, mode, the mean to determine which size of bracelets would need to be made the most.
