Cumulative Review

Hello!

Well... it's Friday after school and I feel horrible about the test today. I really thought that it was very straight-forward and that you would finish it quickly and gain a real boost in your confidence. I was really surprised that you were still working very hard at it by the time the period ended.

I was really proud of you though. You toughed it out and did not give up and even did not complain about it throughout. That is a sign of maturity and hopefully a sign that you understand the purpose of the testing... it is to show you and myself your understanding of the material so far, to see what you need more practise on, and what you already grasp. As much as I am required to submit marks throughout the course, these marks are not a measure of your intelligence, but a measure of your understanding and perhaps, but perhaps not, your effort. Only you can judge that for yourselves.

SO, this is what I've decided to do. There are three areas that the majority of you seemed to struggle with on the test and two are actually somewhat related. I am going to spend one class on each topic next week and then give you back your tests on Thursday to complete.

Monday, topic 1: Changing between the standard form of an equation and point-intercept form and creating an equation of a line given two points.

See http://www.purplemath.com/modules/strtlneq.htm
See http://www.gomath.com/htdocs/lesson/linearequation_lesson1.htm

Tuesday, topic 2: Using the cosine law and solving for either the length of a side of a triangle or one of the angles of a triangle.

See http://www.wsd1.org/waec/math/Applied%20Math%20Advanced/Trigonometry/Cosine%20Law/cosinelawexamples.htm

Wednesday, topic 3: Rational exponents... simplifying polynomial expressions using the exponent laws.

See http://www.purplemath.com/modules/simpexpo.htm for integral exponents
See this link for rational exponents.

Each class your hopework will be to create study notes on these topics (like the math dictionary I had planned for you to complete, but never did assign!)

So, chin up! We are going to get through this!

Have a fantastic weekend,

Miss N.
