### Algebraic Expectation Quiz

### Algebraic Expectation Quiz

Notes to teachers(1):

- On each slide, you will see a ‘student’s work’ and the ‘text book answer’. Students should ask themselves: “How likely is it that the student is on track to get the right answer?”
- We are not interested in special cases.
- We are not interested what the precise wording of the original question may have been.
- We are interested in equivalent expressions.
- While the ‘student’ does not have exactly the same mathematical expression as that presented in the ‘text book’, is their expression at least equivalent? It may not be in ‘simplest form’ but is it at least logically correct?
- We are interested in whether students can identify those cases where no amount of further rearrangement or simplification could result in identical expressions.

Notes to teachers (2):

- Make sure each student has an answer sheet and pen or pencil.
- Use the next 3 slides to explain the concept of the test to your students and get them ready to do the practice questions. Click the mouse or press the right arrow key after each of these introductory slides.
- When you get to the ‘Practice Questions’ slide stress to students that
- each question is shown for a only a few seconds
- they should make a quick judgment and circle their response on the answer sheet
- Click the mouse or press the right arrow key to start the Practice Questions and allow the slide show to proceed automatically until it stops at the ‘Get Ready to Begin’ slide
- When ready, click the mouse or press the right arrow key to start the Quiz and allow the slide show to proceed automatically until a ‘Short Break’ slide.
- You control the length of each ‘Short Break’.
- When ready, click the mouse or press the right arrow key to move on to the next set of automatic slides.

Middle Secondary Years

For each question in the Quiz you will see a student’s answer and the text book answer. Ask yourself ‘How likely do you think it is that the student’s answer is right?’Example:StudentText3+2x 2x+3Definitely Probably No idea Probably Definitelywrong wrong right right

This helps you see when the slide changes

Practice Questions

- There are 3 practice questions.
- You will see each question for only a few seconds.
- Make a quick judgment about the student’s answer

Definitely Probably No idea Probably Definitely wrong wrong right right

- Circle your response on the answer sheet.
