INSTRUCTIONS

GRADE 1-2

1. You have 45 minutes to solve 18 multiple choice problems. For each problem,

circle only one of the proposed five choices. If you circle more than one choice,

your response will be marked as wrong.

2. Record your answers in the response form. Remember that this is the only sheet

that is marked, so make sure you have all your answers transferred here by the

end of the contest.

3. The problems are arranged in three groups. A correct answer of the first 6

problems is worth 3 points. A correct answer of the problems 7-12 is worth 4

points. A correct answer of the problems 13-18 is worth 5 points. For each

incorrect answer, one point is deducted from your score. Each unanswered

question is worth 0 points. To avoid negative scores, you start from 18 points. The

maximum score possible is 90.

4. Calculators and graph paper are not permitted. You are allowed to use rough

paper for draft work.

5. The figures are not drawn to scale. They should be used only for illustration.

6. Remember, you have about 2-3 minutes for each problem; hence, if a problem

appears to be too difficult, save it for later and move on to the other problems.

7. At the end of the allotted time, please submit the response form to the contest

supervisor. Please do not forget to pick up your Certificate of Participation!

Good luck! Canadian Math Kangaroo Contest team
