**Teacher Guidelines**

These guidelines are intended to suggest ways of using this package in class.

**1. Plotting Lesson**

Describe briefly how to plot points on an Argand diagram and then allow the students to begin using the web site. Observe the students performing the plotting task. Allow the students to do the exercise until you feel that they are very comfortable with it.

**2. Manipulation of complex numbers**

Hand out the Formulae page.

The manipulation of complex numbers section should be used to reinforce classroom instruction . All the exercises use a random number generator so that students will get different exercises. Again the teacher should observe the students while they complete the task. A score of 10 is suggested as evidence that the student has mastered the task but the teacher is probably a better judge.

**3. Division**

The division section links with the "Express a quotient in the fornm a+bi" which is directly taken from previous exam papers. An infinite number of questions are asked again using a random number generator and the student should continue until they are very familiar and ten is the recommended number.

**4. Modulus**

The modulus section explains pythagoras theorem and allows the student to practice recognising the sides of a right angled triangle (Adjacent, hypoteneuse and opposite). The lesson continues with a guide to calculating the modulus and is followed by a series of random questions as before.

**5. Quadratics**

This section teaches a student how to solve quadratic equations. Using a random number generator the student is given the opportunity to try out exercises with the support of hints.

**6. Sample Exam**

This allows the students to see examples of questions from Past Papers and gives hints on how they are done. The full worked examples are available when the student is ready for them.

**7. Quiz**

The quiz is based on the entire section and includes some details that have not been covered. The new details are embedded into the question to allow the students to work out links for themselves.
