The topic Negative number word problems is a topic under the 6th grade (U.S.) Math Mission. This exercise involves various word problems that concentrate on interpretations and uses of negative numbers

Types of Problems

There are three types of problems in this exercise:

  1. Determine direction: This problem provides a situation that can be interpreted in one of two possible directions, one positive and one negative. The user is asked to correctly select the interpretation.
    Nnwp1

    Determine direction

  2. Type answer: This problem has a word problem situation where there is an interpretation that could be in either a positive or negative direction. The user is asked to solve the problem and type the answer in the provide box.
    Nnwp2

    Type answer

  3. Interpret zero in situation: This problem has a situation described in which zero can be made to represent a particular place or value. Users are asked to select the correct interpretation of what "zero" represents.
    Nnwp3

    Interpret zero in situation

Strategies

This exercise is medium to get accuracy badges because careful reading is sometimes necessary to see which direction is positive. The speed badges should also be considered medium because of the careful reading that is necessary.

  1. These problems can be done more quickly with a visual interpretation (such as a number line) of the problem.
  2. On Interpret zero in situation the zero point can be determined in the first part of the word problem.

Real-life Applications

  1. Negative numbers are used to represent land below sea level.
  2. Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature.
