## 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.

Instructions

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?**

- Research benefits and drawbacks from computers, Internet, and online learning.
- Use the following parameters to make your informed decision. You may add or subtract or reorganize your parameters.
- Plan a weighted balance to help generate a conclusion to the question.
- Write a simplified annotated inequality with mathematical expressions which describes your decision. Such as:

1.0s_{p}+0.5r_{e}+2e_{m}> 2m_{p}+1.0p_{r}+0.5e_{t}, where:

s

_{p}= Speed of Learning

r_{e}= Easy research

e_{m}= Employable skillsp

_{m}= Mental/Physical

p_{r}= Privacy

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

**Submission**

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