Ways of Thinking: Make Connections

Take notes about your classmates’ methods for adding and subtracting positive and negative fractions and decimals.


As other students present, ask questions such as:

  • Are you sure you moved the correct number of units for the second number?
  • Are you sure you moved in the correct direction for the second number?
  • Can you explain again how you found your answer?
  • How did you decide which operations you needed to perform in order to solve the problem?
  • Shouldn’t the answer to that problem be negative?
  • How does your explanation compare with that of other students?
