Balancing Informed Decision

Type: Investigation

Theme: Inequalities

Grades: 5, 6, 7, 8, 9, 10, 11, 12

Learning Target: Students will create a weighted balance, write an inequality, and use a spreadsheet to make an informed decision.


This project is for groups of two. Please create a one-page within a group PowerPoint. You will be answering the following question using researched information and a weighted balance.

Question: Should computers and the Internet be used to learn mathematics the majority of time?

  1. Research benefits and drawbacks from computers, Internet, and online learning.
  2. Use the following parameters to make your informed decision. You may add or subtract or reorganize your parameters.
  3. Plan a weighted balance to help generate a conclusion to the question.
  4. Write a simplified annotated inequality with mathematical expressions which describes your decision. Such as:
      1.0sp+0.5re+2em > 2mp+1.0pr+0.5et, where:

    sp = Speed of Learning 
    re = Easy research 
    em = Employable skills 

    pm = Mental/Physical
    pr = Privacy
    et = Ethical

  5. Use a spreadsheet to calculate the weights of your decision.
  6. Obtain and provide a Peer Review.
  7. Create a diagram in PowerPoint (1 slide) showing your weighted balance.
  8. Research: Which downstream communities rely on water from the glacier?
  9. Write a brief one paragraph conclusion. Enter it into the Note field in the group PowerPoint presentation.


  1. One page in group PowerPoint.
  2. Provide a document with at least three references.
  3. Submit a Peer Review.
