Developing Mathematical Literacy: TIPS4RM put out this document to help teachers develop and implement the Three Part Lesson into their math classroom which promotes math talk and the sharing of mathematical ideas.



GIZMOS: Please check out Gizmos for your students. Gizmos are online simulations for students in Grade 3 -12 for math and science. Please contact Evelyn Heath at Evelyn.Heath@tdsb.on.ca to get set up on Gizmos.




Grade 8:
Students design a rollercoaster or skateboard park using circles. They use circumference and area formulas to find the length of the coaster and the area underneath it. At first it seems complicated but once they get started they get. I have to keep reminding them to keep it simple! I've attached the outline, the rubric and my examples. I will have the students examples up shortly. Submitted by Sudeep Sanyal, Karen Kain School of the Arts.

Example Pieces of Work

Title: A Dicey Situation
Grade(s): 7 & 8
Strand(s): Data Management & Probability
Problem:
Jamie made up a new dice game. Two players each roll an ordinary six-sided die. Of the two numbers shown, the smaller number is subtracted from the larger.
Scoring:- If the difference is 0, 1, or 2, player A gets 1 point.- If the difference is 3, 4, or 5, player B gets 1 point.
The game ends after 12 rounds. The player with the most points wins the game.
A) If you are given the choice of being Player A or Player B, which would you pick, assuming you want to win? (Remember to explain all the steps you use in making your decision.)
B) Describe another way of scoring that is fair for this game of differences. Explain how you know it is fair.

What to look for: Students should be given the opportunity to play the game with a partner. Level four students might make the connection immediately as to who is more likely to win, but they can still be expected to calculate the individual probabilities.

Title: The Monty Hall Problem
Grade(s): 8, 7 and 6
Strand(s): Data Management & Probability, Number Sense (fractions)
Problem:
You are on a game show and you are presented with a choice of 3 doors. Behind one is a luxury car, and behind the two others are nothing. The game show host asks you to pick one of the doors.
After you select one, and as part of the game, the host opens an unpicked door which he knows to be empty. You are asked if you would like to keep the door that you chose, or switch your choice to the remaining unopened door.
Should you switch? Why or why not?

What to look for: This problem can be examined by using a tree diagram. If computers are available, students may try the link below. It is a Monty Hall Problem simulator that works quite well and keeps track of their choices so that they can work out the probabilities on the go.

Title: Squares & Circles
Grade(s): 8
Strand(s): Measurement
Problem:This is simply an extra worksheet that can be used for students to practice and apply the formulas for area and circumference of circles.
What to look for: Questions 12-15 can be quite tricky. Their solutions require students to divide the square into triangles and apply the formula for the area of a triangle. If they are not prompted beforehand they will often miss this point.

Title: Burning Candle
Grade(s): 8,7
Strand(s): Data Management & Probability
Problem:
Candle manufacturer companies advertise that their products are better quality and have the longest mean burning times. John decides to select same size candles form three different companies, Bright Candle, Fire Candle and Shiny Candle – and do an experiment with 15 candles in order to test which company has a better product. He recorded the number of minutes that each candle burned.
(see .pdf for list of values and remainder of question).
What to look for: This question can be used to prompt a discussion about the most appropriate measure of central tendency (mean, median and mode).

Title: Painted Cubes
Grade(s): 8,7,6
Strand(s): Patterning & Algebra, Number Sense
Problem:
A toy company wants to create and sell a game that uses solid colored cubes of varying sizes. They use smaller cube-a-links to create (solid) cubes that are 2x2x2, 3x3x3, 4x4x4 and so on.
Once the larger cubes are created, they are dipped (fully) into red paint, so that the outsides are painted entirely red.
The company wants to keep track of the paint they use, but they must first know how many cube-a-link faces are painted.
Size of large cube
# of small cubes with 3 red faces
# of small cubes with 2 red faces
# of small cubes with 1 red face
# of small cubes with 0 red faces
Total # of small cubes
2x2x2





3x3x3





4x4x4





5x5x5





6x6x6

















10x10x10





nxnxn





Can you see the patterns in the table?
Can you generalize these patterns (create equations predicting how many cubes with 3, 2,1,0 and total) for a large cube nxnxn?
How are those equations (or columns) related to what you see?

What to look for: Generalized patterns can be observed by completing the missing values in each column. (Each column generates a separate equation). The nice part about this problem is that it affords an opportunity to relate the equations to visual patterns.
