The Chocolate Princess

Tonight I am marking a Cubic Functions test ready for my year 11 Maths Methods class, first session tomorrow morning. We will start studying Circular functions so I called into the supermarket to buy 20 paper plates. We will use them to draw a unit circle with divisions marked in degrees and radians. We may then develop the sine, cosine and tangent graphs from them?

When I arrive in class I expect “The Chocolate Princess” will be there loaded up with a good supply of chocolate. Checkout Chick by night and talented Maths student by day – she sure loves her chocolate! After payday “The Chocolate Princess” buys her fav choc bars and takes advantage of a staff discount as well.

Luckily their are current studies whose findings show: How eating chocolate can help improve your maths.

Here is a problem I will pose to “The Chocolate Princess”:

The chocolate Princess has broken her 8 x 3 block into 4 equal pieces as shown. Now she can share her yummy chocolate with her 3 best friends. With 3 straight breaks, in how many different ways could the block be divided? With each case, what fraction would each person get?
