  Each tutorial explains the concepts of significant digits using explanations, step by step examples, and practice problems. In this screen, students are shown how increasing the number of decimal places in a number also increases its precision. Students can interact by shooting at an object and see how the changes in precision affect the chance of hitting the object.

After each tutorial, students can practice their understanding by taking a 25 question quiz of randomly selected problems. The goal is to get 90% or above on each of the four drills. In this screen, students must read the instrument correctly using the correct number of significant digits.
