1. 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.

2. Notes to teachers (2):
Make sure each student has an answer sheet and pen or pencil.
Use the next 4 slides to explain the concept of the test to your students.
Explain that they will only see each item for a few seconds. Your students should make a quick judgment and circle their response for that item on the answer sheet.
You should click the mouse or press the right arrow key after each of these introductory slides.
Once you reach the first test item, N1, allow the slide show to proceed automatically until the ‘short break’.
You control the length of this short break. Click the mouse or press the right arrow key to move on to the second set of automatic slides.

3. Algebraic Expectation Quiz
Middle Secondary Years

4. In this series of questions you will see a student’s answers and the text book answers. For each question ask yourself ‘How likely do you think it is that the student’s answer is right?’ Example: Student Text x x Definitely Probably No idea Probably Definitely wrong wrong right right
This helps you see when the slide changes

5. Example
Student Text (x+x) x Definitely Probably No idea Probably Definitely wrong wrong right right
