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.
