Learning Target Quiz 1

This is your first Learning Target quiz! This quiz contains questions for Learning Targets 1 and 2.

• It's to your advantage to attempt as many problems as possible. But you do not need to attempt all the problems. Only attempt the ones you believe you are ready to take.
• Do your work on separate pages with each Learning Target on its own separate page. Please do not put multiple Learning Targets on the same page.
• Make sure to consult the Standards for Assessments in MTH 225 document before starting on your work, so you're clear on what is expected and what constitutes a "successful" attempt.
• When you are done: Scan each Learning Target to a clear, legible, black-and-white PDF and upload the PDF to the designated folder on Blackboard. Remember do not just take a picture with your camera –- use a scanning app to create a PDF, and upload the PDF.
