Pros

  • Video can be paused to allow time for calculations
  • Uses estimation for plotting fractions and decimals
Cons

  • Learners are expected to be able to convert rational numbers on their own
  • Does not show conversions
  • Fast-paced video
  • Limited reasoning for plotting points with estimation
  • Video does not reflect stated 6.ns.6a standard but more closely reflects 6.ns.6c standard which is to position rational numbers on a number line
