Exponent Power

You can use some 3’s for the base and some for the exponents. Using a calculator to help you, show that the largest number occurs when you develop the expression 33 × 3 × 3.

Pong Soccer

The ping pong ball has a smaller radius than the soccer ball. Therefore, it must fall farther before it hits the ground.

Polly Wolly Doodle

You can start by noticing that db = b. Therefore, b must be half of d. Try each case: 8 and 4, 6 and 3, 4 and 2, and 2 and 1. One possible solution is a =1, b = 4, c = 5, and d = 8. Are there any others?

Pattern Puzzle

Divide the number in the first column by the number in the second column. Then, multiply by 3. The missing number is 18.

Magic Polynomials

Represent the polynomial as ax3 + bx2 + cx + d.

If x = 10, this becomes 1000a + 100b + 10c + d.

Comparing this to 2351, the polynomial must be 2x3 + 3x2 + 5x + 1.

DaVinci Goes Linear

Replace each letter by the letter that is 3 to its left in the alphabet. For example, P becomes M. The decoded message is MEETATSIX.

Present for Damian

Let x represent the cost of the item.

The table summarizes the provided data.

Friend

Costx

Anwar

x – 15

Grace

x – 14

Colin

x – 13

Diana

x – 12

Evan

x – 11

The cost of the present must be greater than the total amount of dollars of the five friends.

x > x – 15 + x – 14 + x – 13 + x – 12 + x – 11

x > 5x – 65

x < 16.25

Since Anwar is $15 short, x > 15. The only integer that satisfies both inequalities is 16. Therefore, the present cost $16.

On a Tangent

When Allan lets the string go, the ball will continue along a tangent to the circle. Deirdre is most likely to catch the ball.

Deserted Island

The number of rations available when the plane landed on the island was 120 × 15 = 1800.

At the end of five days, 120 × 5 = 600 rations had been used.

So, there were 1800 – 600 = 1200 rations remaining.

Tips for Students
Why Studying Math is Different
Take Charge and Take Action
Preparing for Tests

Why Studying Math is Different
  • Reading a math resource is not like reading a novel. You may have to stop and think about some ideas before proceeding.
  • Math is a cumulative subject. If you miss a concept one day, it may come back to haunt you and could even prevent you from understanding concepts you study later. Always get help as soon as you recognize that you have a problem.
  • Build up a network of math partners you can consult if you run into a roadblock. These are the days of easy communication. Telephone, email, and instant messaging are all available. Use them.
Take Charge and Take Action
  • Take responsibility for your own success. If you find that you don’t know or understand something, take whatever steps are necessary to fix the problem. Do not let others distract you from your purpose.
  • Be an active participant in the classroom. Volunteer answers to questions and offer to place solutions on the blackboard. Ask questions immediately when you think you have lost the thread of the lesson.
  • Math is learned by doing problems. Although you need to know some facts and procedures, you get really good at math by working through problems. It’s wise to work on a problem yourself as much as possible. You may need to ask for help at some point, but do not give up too easily. The more you can do on your own, the more your brain will develop and the easier future problems will seem.
  • Problem solving is one of the key skills in the study of math. There are tips for problem solving starting on page xv in the front of MathLinks 9. Your teacher will show you additional strategies that you can use. In short, the steps are:
    • Understand the problem.
    • Plan how to solve it.
    • Do It! Carry out your plan.
    • Look Back. Review how you solved the problem and the answer you received. Does it make sense? If the answer seems unreasonable, it may be necessary to look for errors or select another strategy.
  • Before beginning an assignment, review your class notes. Ensure that you understand the worked examples and the meaning of any new terms. Consider highlighting important concepts, equations, or definitions.
  • As you work on each chapter, use the Foldable™ at the beginning of the chapter to keep track of information from the chapter, including Key Words, examples, Key Ideas, and what you need to work on.
  • If you have completed the assigned problems, but still don’t feel comfortable with the concepts, do a few more. Most teachers will assign about half of the problems in a given exercise. If you run out of Practise questions before you feel comfortable with the concepts, ask the teacher for more. The Student Centre section of the MathLinks 9 Online Learning Centrehas many things to help you.
  • If you find that you need some help or a hint to proceed with the solution to a problem, be careful not to get too much help. You want a coach, not a handout. Once you see where to go, thank your coach. Do not ask for the entire solution. That robs you of an important learning opportunity.
  • Remember that you have not failed at solving a question until you quit. Sometimes it is useful to skip a tricky question after thinking about it for a few minutes and then come back to it later.
  • If there is any reason why you cannot finish your entire math assignment, it is better to do a few problems from each part than to do just the first problems in the assignment.
  • If the homework load is light on a given day, use the extra time to review and practise concepts covered earlier in the course.
  • Allow a few minutes at the end of your math work session to have a look at the next lesson so that you know what is coming up. It is not necessary to work through the lesson, just to get a feeling for what is going to happen in the next math class.
Preparing for Tests
  • If you do your homework conscientiously and work at fixing problems as they occur, then preparing for tests becomes much easier. All you need to do is remind yourself of the concepts that you are going to be tested on and do some sample problems to sharpen your skills.
  • When you get your test, take a minute or two to look it over. You do not have to do #1 first. If you know how to attack #3, then do that one first.
  • Do not get bogged down on a question. If your strategy does not seem to be working and you are stuck for an alternative, go on to another question.
  • Sometimes you will not finish a test in the time allotted. If this seems to be happening, do not panic. Accept that you are not going to finish. Make it your goal to do as many questions as you can before the time runs out.
  • Read each question carefully. Be sure that you answer what is being asked.
  • Show all of your work. If you make an error and arrive at the wrong answer, you will at least get partial marks.
  • If you have time left, use it to verify your answers. You can sometimes work backwards to do this. Alternatively, you can solve the same question a different way. Be sure to check calculations. A slip of the finger on a calculator can easily lead to a wrong answer.
  • Watch out for panic attacks or "freezeups". This occasionally happens to many students on a test. Time may be short, solutions are not going well, and you have an overwhelming sense of panic. The best thing to do is STOP. Turn the test over on your desk. Take several deep breaths, exhaling slowly. Remind yourself that you prepared for this test and that you can do most, probably all, of the questions on it. Then, return to the test, select a question that you can do, and work through it.
  • If panic becomes a serious problem, consider learning one or more relaxation techniques or consulting a counselor for other strategies. Keep in mind that these will not help if the real source of the panic is inadequate preparation for the test.

Power Roll (Any Number of Players)

Materials Needed:
• scissors
• two six-sided dice
BLM: Power Roll Cards (26.0K)

1. Print and cut out the cards on BLM: Power Roll Cards. Shuffle the cards.

2. Before playing the game, players decide whether to play for a certain length of time or for a certain number of rounds.

3. Each player rolls one die to decide who will play first. The player with the highest roll goes first. If there is a tie, roll again.

4. The first player draws a card from the pile and rolls the dice. The objective is to use one rolled number as the base and the other rolled number as the exponent to form a power that is equal to the number on the card. Each player gets 10 rolls to achieve this. Use the table to determine the scores.

Number of Rolls Score
1 10
2 9
3 8
4 7
5 6
6 5
7 4
8 3
9 2
10 1

Example: Sara’s card is 32. She rolls a 2 and a 5 on the fifth roll to form 25. Her score is 6 points.

5. Once a player forms an equivalent power or uses up all 10 rolls, play passes to the next player.

6. Play continues for as long as players wish. The winner is the player with the highest score.

Licence Plates (Any Number of Players)

Materials Needed:
• chips or tokens of two colours

1. The object is for players to observe licence plates on motor vehicles in a parking lot and note the last two numbers on each plate. They continue to observe licence plates until a match is found or they note 20 licence plates. This completes a round of play. Before doing so, each player makes a prediction about whether or not there will be a match.

2. One player acts as the bank and distributes five chips of the appropriate colour to each player.
• Players who predict there will be a match get chips of one colour.
• Players who predict there will not be a match get chips of another colour.
Players play against the bank.

3. The winners in a round receive a chip. The losers must pay a chip.

4. Play at least six rounds.

5. Determine which prediction is more likely to win.
