Q1 Compare Products

19. Buyer Beware


Buying and selling on the Internet has changed the way we live. We can now perform a web search to locate, compare, and buy goods and services.

In this Quest you are going to compare the pros and cons of different products.

During this Quest, you are going to compare specifications of three different devices, compare products and select the best choice for your classroom based on features and cost.  

Key Vocabulary:

Memory: measured in Bytes (eg. Gigabytes) of information able to be stored on a computer. Example: 1 Gigabyte of storage can hold approximately 200 songs.

Screen Size: is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches

Resolution: number of distinct pixels in each dimension that can be displayed on a device and determines how sharp the image is on the screen

Processor: a part of a computer, such as the central processing unit, that performs calculations or other manipulations of data

Specifications: a detailed description of the features, operating system, amount of memory, processor speed, etc.


1. Your class is receiving a grant of $6,000. You have been asked to evaluate and recommend a tablet device to purchase from Samsung, Apple, Amazon.

2. Open, Copy and Save this Tablet Product Specifications Chart. The chart includes a blank column for a device your school might already be using or is considering for purchase.

3. Discuss the importance of the different features of each device in a small group or as a class and identify pros and cons. 

  • Memory, storage, resolution & screensize, processor, price.
  • Consider whether other features are important for your class work:

    cameras, the ability to attach a monitor or projector to it, keyboard or touchscreen, USB port for external devices...

4. Calculate how many of each device can be purchased with the grant funds.

5. Select one device (or the one your school is already using or considering) and make a recommendation to the rest of the class with at least 3 reasons why you selected it. Document this on your copy of the Tablet product chart in the table provided at the bottom of it.

6. Save and share your Tablet product chart and final recommendation with your teacher.

Bonus activities:

1. Your small groups can present and defend your recommended device to the rest of the class for a final class vote for a single device recommendation.

2. Invite your school or district technology director to present your recommendation and ask how the school/district makes a decision.

3. An anonymous donor has offered to match the grant. Will this make a difference to your recommendation?

4. Search Amazon for the device chosen and read the user reviews. Does this change your recommendation?
