Take out a pencil and a piece of paper. Write down your name and title the paper – Chapter 1 Pre-assessment. This series of pre-assessments is designed to assess what you know and don’t know about Equations and Expressions, the topics in Chapter 1. Your answers will be used to create your assignment list for the chapter. Questions will stay on the board for a limited amount of time. Please take this time to workout, calculate and/or answer the question. If you don’t know the answer, do your best to either guess or write down thoughts or partial guesses. Blank answers and no responses are most detrimental as I will have to assume you have absolutely no idea. Even wrong answers give an idea of what you are thinking. Questions with a calculator with a Green circle mean you MUST explain how to use the calculator to solve the problem. While it may be possible to solve without the calculator, points are awarded based on your answers of HOW to use the calculator to solve the problem.
