This packet contains notes on signficant figures and how to record answers to calculations. The notes include 7 rules for counting signficant figures and the practice questions ask students to detail which of the 7 rules that was applied to counting the significant figures. By requiring students to give the rules, the process of looking at the notes to determine the correct number of significant figures is reinforced. The section on the recording calculated answers gives the rules and the thought process to get to the correctly recorded answers. There is a section that has the students to step-wise go through the thought process for each of the four mathematical functions. Finally, there is a section that has the students correctly perform calcuations and record their answers correctly.
