Hello my future teachers! Below is a list of topics that I would love for one of you to teach:
Sales Tax
Prime Factorization
GCF / LCM
Mode, Median, Mean, Range
Probability
Lines of Symmetry
Coordinate Plane - Shapes
Graphs
You will need to come up with a lesson plan which includes a teaching objective, an explanation, an activity, an assignment, and an assessment...
Please let me know if you are interested in any of these topics or have your own that you would like to do!

7-5 Working with Percents
% multiplied by "of" = 100 mutliplied by "is" ...
ALL PERCENT PROBLEMS!
There are four items or elements to each percent problem. One of them is always 100. Therefore, there are three possible unknowns in the problem - you must be given at least two of the three. Fill the known values into the above equation and solve for the unknown...
The above equation should be written first for ALL problems! Then your paper should show a logical, vertical progression revealing each step to ultimately arrive at the answer.

9-3 Area of Circles
Area of a Circle = Pi x radius squared.
Radius = 1/2 of the diameter of a circle.
Pi is approx = to 3.14
Circumference = 2 x Pi x Radius
draw the picture! make sure that your answer makes sense!
Always use Pi = 3.14 not 22/7!!!
REMEMBER - a number raised to the power of 2 is not MULTIPLIED by 2 it means to multiply the number times itself!

9-2 Areas of Quadrilaterals
Area of parallelogram = Base X Height
Base can be the length of any of the four sides.
Height is the perpendicular distance (the distance that forms a right angle with the chosen base) from the base to the opposite side.
Area of trapezoid = (b1+b2)H / 2; length of base 1 plus length of base 2 multiplied by the height and then divided by 2.
The bases of the trapezoid are the parallel sides. The height is the perpendicular distance between the bases.

9-1 Areas of Rectangles and Triangles
Area of Rectangle = length x width
The length and width of the rectangle can be either measurement...
Area of Triangle = base x height / 2
The area of trianlge is 1/2 the area of the rectangle that contains it!
A hectare = 10,000 square meters
Please draw a picture for EVERY problem!
Please write a formula for EVERY problem!
