Strategies

This exercise is easy to get accuracy and speed badges because there is only one type of problem and the manipulative is very easy to use.

  1. The non-visible tick marks on the manipulate are change and are based on the fraction you are working with. For example, when your fraction has a denominator of three, the hidden ticks marks are in thirds.
  2. It is sometimes easier to move from a larger number back a few spots rather than counting upwards every time.

Real-life Applications

  1. Negative numbers are used to represent land below sea level.
