2 Foreword Avant-Propos

The Centre for Education in Mathematics and Computing is pleased to announce the results of the 2019 Canadian Senior and Intermediate Mathematics Contests.

Our congratulations go to all who participated in this year’s CSMC and CIMC. This year’s Contests were re- sounding successes, with averages of 31.3 and 29.1, respectively.

As always, we would like to thank the hard-working Problems Committees. Many of the members of these Com- mittees are active secondary school teachers who volunteer their time and contribute dozens of hours of expertise. Without their intriguing and sometimes amusing problems, these Contests would not be possible.

We would also like to thank all participants, both teachers and students. We hope that the papers provided you with some interesting mathematics to think about and play with. Thank you for your support! Please con- tinue to encourage your colleagues and fellow students to become involved in our activities.

Le Centre d’éducation en mathématiques et en informatique à d’annoncer les résultats du Conours canadiens de mathématiques de niveau supérieur et intermédiaire 2019.

Nos félicitations vont à tous les participants du CCMS et du CCMI de cette année. Les Concours de cette année retentissaient de succès, avec des moyennes de 31,3 et 29,1, respectivement.

Nous aimerions surtout remercier les Comités de problèmes pour leur dur travail. Plusieurs membres de ces Comités sont des enseignant(e)s d’école secondaire actifs qui offre leur temps et contribuent des douzaines d’heures d’expertise. Sans leurs problèmes perspicaces et amusants, ces Concours ne seraient pas possibles.

Nous aimerions remercier aussi tous les participants incluant les enseignants et les étudiants. Nous espérons que les concours vous ont offert des mathématiques intéressantes qui vous ont amusées et portées à réfléchir. Merci pour votre soutien continué!

3 Comments on the Contests

CANADIAN SENIOR MATHEMATICS CONTEST Part A 1. Very well done. When errors were made, they were usually subtraction errors or reporting the incorrect person’s age. Average: 4.9

2. Well done. There were many errors in the formula for the circumference of a circle that was used by contestants, and thus many variations in the final answers given. The other major source of error was the unnecessary substitution of an approximation for π. If a decimal approximation is needed for further computation, the substitution of an approximation for π should be made at the latest possible step in the calculation. Since the length of the side of the triangle was asked for, there was no need to approximate the answer. Average: 4.0

3. Most students were able to correctly determine the product of powers. Determining the sum of powers proved more difficult. A common mistake was to say that 2403 + 2403 = 4403. Another common mistake was to drop the bases of 2 before simplifying the sum, resulting in an incorrect answer of 242. Average: 3.6

4. Most students understood how to approach this question and were able to find values of x that satisfy x2 ≤ x + 6. Most mistakes were related to miscounting the number of possible values of y that correspond with each value of x. Some students graphed y = x2 and y = x + 6 and then counted the number of “lattice points” in the appropriate region. Average: 2.7

5. Of the students who solved this problem, many recognized that 605 = 11 × 55 and scaled the relatively unknown Pythagorean Triple (48, 55, 73) to get 48 × 11 = 528. (Note that this approach does not show that 528 is the largest possibility less than 605, but since the correct answer of 528 was in the box, this still would have gotten 5 marks.) A common incorrect answer was 604; in solutions with this answer, there often was not much written down and we suspect students simply misinterpreted the question. Average: 1.0

6. There were various common mistakes we saw in Question 6. Some students switched the roles of k and 4 − k 4 and ended up with k = 3 , this usually earned 4 of the available 5 marks. If the correct answer was not in the box, we required justification for the formula for the area of 4ARS. The question does not state that k must be an integer, but some students assumed that it must be and simply tested possible integer values for k. Average: 0.7 Part B 1. This question was very well done. In part (b), a few students found values for t and r where t was not in the required range. In part (c), a few students missed that a, b and c were positive integers, and concluded that the minimum possible value of c was 0. Average: 8.8

2. Part (a) was generally well done. When asked for the value of w, that is what should be given rather than a 1 1 value of . In part (b), many contestants tested several values and made the conclusion that x = , which w 2 was the correct value of x. However, having explored and found what appears to be the value of x, it must 1 now be shown using general mathematical methods that the value of x is, in fact, always . 2 Solutions for part (c) required the solution of a cubic equation and some indication of why two of the three roots were inadmissible. Frequent errors were dividing out a linear factor (such as (r − 1)) without giving

reasons why it was allowable to do this. In either approach, the condition of the question forced r 6= 1, and thus r − 1 6= 0, and the division was allowed. These things were rarely explained leading to less than fully correct solutions. Average: 4.4

3. Part (a) was fairly well done and we saw many different solutions. Most students exploited known facts about 30◦-60◦-90◦ triangles to find concise solutions. There were also many ways to solve part (b). Most methods started with a simple construction followed by a few calculations to arrive at an equation equivalent to r2 = 4r. Very few students attempted part (c). Of those who got started, most got lost in the algebra. Average: 1.2

CANADIAN INTERMEDIATE MATHEMATICS CONTEST Part A

1. Well done. Some students who had the incorrect answer could have received some part marks, but did not since all of their calculations were just numbers that were not attached to any part of the labelled diagram. Average: 4.5

2. Well done. Some students calculated how many quarters were equal to 20 dimes rather than how many additional quarters were required to match Binh’s total. Average: 4.4

3. Students struggled with this problem. If they were unable to determine the prime factorization, it was difficult for them to proceed. Common errors included mismatching the exponents on 2, 3 and 5, or miscalculating 3a+4b+6c with those exponents. Some students attempted to factor 36 000 into powers of 3, 4 and 6. Other students multiplied 2 × 3 × 5 = 30 and tried to write 36 000 as a power of 30. Average: 3.1

4. Well done. Many students either got a subset or a superset of {14, 15, 16}. Some students had a table showing scenarios, but that was not labelled well enough to earn significant part marks. Average: 3.8

5. Many students correctly tried to use case work to solve this problem and recognized that the values of a and b had to be between −10 and 10. The problem many students faced was that their cases double-counted some solutions or weren’t exhaustive. Some of these problems could have been avoided by a more organized approach. Average: 1.5

6. This problem was difficult for most students. Some students correctly recognized that the radius of the larger cone was double the radius of the smaller cone. However, they incorrectly assumed that the heights of the cones were the same. Many students struggled to simplify the algebraic expressions in a useful manner. Average: 0.4

Part B

1. Part (a) was quite well done. Common miscalculations were AC√ =√ 13 and CB = 3. Some students tried to do part (a) using slopes. In (b), some students calcualted 45 : 20 (or approximations achieving full marks). Others simplified incorrectly to 9 : 4 or to 2 : 3, earning part marks. Others introduced a negative by setting up the ratio improperly. Part (c) had many different possible approaches that could be successful. We also saw a number of approaches that were either incorrect or unnecessarily unwieldly, such as quadratics in x and y. Some students tried to adapt the midpoint formula in an arbitrary way, or tried to use it without modification. Students took F outside of D and E. Others introduced absolute values in the ratio equation, yielding two solutions for F . Some students provided the final answer without justification or demonstrating trial and error. Some students seemed to forget to attempt part (d). Students might set up one equation correctly and the other incorrectly. Some students provided the final answer without justification. Average: 6.4

2. Part (a) was very well done. Students struggled more with parts (b), (c) and (d). In some solutions, students equated the two digit integer “xy” with x + y instead of with 10x + y. In part (b), some solutions forgot to eliminate the cases where the values of x and y were not single digits. In parts (b) and (c), some students found the answers by trial and error, but did not show that there were no other solutions. In part (d), many solutions were missing cases, and some solutions had extra cases. Average: 3.6

6 Comments on the Contests

3. If the division was done correctly in part (a), students usually got the right answer. In part (b), some students attempted to use specific values for L, M and R (particularly the values from part (a)) which did not lead to a general argument. Some students incorrectly assumed that the shares of chocolate must be integers. If students deduced correct inequalities, this usually led to a successful contradiction argument. Part (c) was a very challenging problem. Many students correctly attempted to look for a pattern in the table but they were too quickly convinced of patterns which were in fact not true. Average: 1.3

CONCOURS CANADIEN DE MATHÉMATIQUES DE NIVEAU SUPÉRIEUR Partie A 1. Ce problème a été très bien réussi. Si des erreurs ont été commises, il s’agissait généralement d’erreurs de soustraction ou bien l’âge de la mauvaise personne fut reporté. Moyenne: 4,9

2. Ce problème a été bien réussi. Il y a eu beaucoup d’erreurs dans la formule de la circonférence d’un cercle utilisée par les participants, et donc beaucoup de variations dans les réponses finales données. L’autre source d’erreur majeure venait de la substitution inutile d’une approximation pour π. Si une approximation décimale est nécessaire pour un calcul ultérieur, la substitution d’une approximation pour π devrait être faite le plus tard possible dans les étapes de calcul. Comme la longueur du côté du triangle était demandée, il n’était pas nécessaire de faire une approximation de la réponse. Moyenne: 4,4

3. La plupart des étudiants ont été capables de déterminer correctement le produit des puissances. Déterminer la somme des puissances s’est avérée plus difficile. Une erreur courante était de dire que 2403 + 2403 = 4403. Une autre erreur courante était d’abandonner les bases de 2 avant de simplifier la somme, ce qui a donné une réponse incorrecte de 242. Moyenne: 3,6

4. La plupart des élèves ont compris comment aborder cette question et ont pu trouver des valeurs de x qui satisfont x2 ≤ x + 6. La plupart des erreurs étaient liées à un mauvais décompte du nombre de valeurs possibles de y qui correspondent à chaque valeur de x. Certains élèves ont représenté graphiquement y = x2 et y = x + 6 et ont ensuite compté le nombre de « points de réseau » dans la région appropriée. Moyenne: 2,7

5. Parmi les élèves ayant résolu ce problème, beaucoup ont reconnu que 605 = 11 × 55 et ont mis à l’échelle le, relativement peu connu, Triplet de Pythagore (48, 55, 73) pour obtenir 48 × 11 = 528. (Notez que cette approche ne montre pas que 528 est la plus grande possibilité inférieure à 605, mais si la bonne réponse, 528, était dans la case, cette réponse aurait quand même obtenu 5 points). Une réponse incorrecte courante était 604. Les solutions comportant cette réponse étaient souvent peu rédigées et nous soupçonnons que les étudiants aient simplement mal interprété la question. Moyenne: 1,0

6. Nous avons vu plusieurs erreurs fréquentes dans la question 6. Certains étudiants ont inversé les rôles de k 4 et 4 − k et ont obtenu k = 3 , ce qui correspond généralement à gagner 4 des 5 points possibles pour cette question. Si la bonne réponse n’était pas dans la case, nous attendions une justification de la formule de l’aire de 4ARS. La question ne précise pas que k doit être un nombre entier, mais certains étudiants ont supposé qu’il devait l’être et ont simplement testé les valeurs possibles pour k. Moyenne: 0,7 Partie B 1. Cette question a été très bien réussie. Dans la partie (b), certains étudiants ont trouvé des valeurs pour t et r où t n’était pas dans l’intervalle requis. Dans la partie (c), certains étudiants n’ont pas remarqué que a, b et c étaient des entiers positifs, et ont conclu que la plus petite valeur possible de c était 0. Moyenne: 8,8

2. La partie (a) a été généralement bien réussie. Lorsqu’on demande la valeur de w, c’est cette valeur qui devrait 1 être indiquée plutôt que la valeur de . Dans la partie (b), de nombreux participants ont testé plusieurs w 1 valeurs et ont conclu que x = , ce qui était la valeur correcte de x. Cependant, après avoir exploré et 2 trouvé ce qui semble être la valeur de x, cela doit être ensuite démontré, à l’aide de méthodes mathématiques

1 générales, que la valeur de x est, en fait, toujours . Les solutions de la partie (c) nécessitaient la solution 2 d’une équation cubique et une indication des raisons pour lesquelles deux des trois racines n’étaient pas admissibles. Les erreurs fréquentes consistaient à diviser un facteur linéaire (tell que (r − 1)) sans donner les raisons pour lesquelles cela était autorisé. Dans l’une ou l’autre approche, la condition de la question imposait r 6= 1, et donc r − 1 6= 0, et la division était permise. Ces éléments étaient rarement expliqués, ce qui a conduit à des solutions partiellement correctes. Moyenne: 4,4

3. La partie (a) a été assez bien réussie et nous avons pu apprécier de nombreuses solutions différentes. La plupart des étudiants ont exploité les éléments connus concernant les triangles 30◦-60◦-90◦ pour trouver des solutions concises. Il y avait également de nombreuses façons de résoudre la partie (b). La plupart des méthodes commençaient par une construction simple suivie de quelques calculs pour arriver à une équation équivalente à r2 = 4r. Très peu d’étudiants ont tenté la partie (c). Parmi ceux qui l’ont commencé, la plupart se sont perdus dans l’algèbre. Moyenne: 1,2

CONCOURS CANADIEN DE MATHÉMATIQUES DE NIVEAU INTERMÉDIAIRE Partie A

1. Cette question a été bien réussie. Certains étudiants ayant donné une mauvaise réponse auraient pu recevoir des notes partielles, mais cela n’a pas été le cas parce que tous leurs calculs n’étaient que des nombres, non attachés à une partie de la figure annotée. Moyenne: 4,5

2. Cette question a été bien réussie. Certains étudiants ont calculé combien de pièces de vingt-cinq cents étaient égales à 20 pièces de dix cents au lieu du nombre de pièces de vingt-cinq cents nécessaires pour être égal au total de Binh. Moyenne: 4,4

3. Les étudiants ont eu des difficultés avec ce problème. S’ils ne parvenaient pas à déterminer la factorisation première, il leur était difficile de poursuivre. Les erreurs les plus courantes consistaient à ne pas faire corre- spondre les exposants de 2, 3 et 5, ou à mal calculer 3a + 4b + 6c avec ces exposants. Certains étudiants ont tenté de factoriser 36 000 en puissance de 3, 4 et 6. D’autres étudiants ont multiplié 2 × 3 × 5 = 30, et ont essayé d’écrire 36 000 comme une puissance de 30. Moyenne: 3,1

4. Cette question a été bien réussie. De nombreux étudiants ont soit obtenu un sous-ensemble ou un sur-ensemble de {14, 15, 16}. Certains étudiants ont créé un tableau de scénarios, mais il n’était pas suffisamment bien annoté pour obtenir des notes partielles substantielles. Moyenne: 3,8

5. De nombreux étudiants ont judicieusement essayé d’utiliser des études de cas pour résoudre ce problème et ont reconnu que les valeurs de a et b devaient être comprises entre −10 et 10. Le problème auquel de nombreux étudiants ont été confrontés était que leurs cas comptaient deux fois certaines solutions ou n’étaient pas exhaustifs. Certains de ces problèmes auraient pu être évités par une approche plus organisée. Moyenne: 1,5

6. Ce problème a été difficile pour la plupart des étudiants. Certains étudiants ont reconnu, à juste titre, que le rayon du grand cône était le double du rayon du petit cône. Cependant, ils ont supposés, à tort, que les hauteurs des cônes étaient les mêmes. Beaucoup d’étudiants ont rencontrer des difficultés à simplifier les expressions algébriques de manière utile. Moyenne: 0,4

Partie B

1. La partie (a) a été assez bien réussie. Les erreurs de calcul les plus courantes étaient AC = 13 et CB = 3. Certains étudiants√ √ ont essayé de faire la partie (a) en utilisant des pentes. Dans la partie (b), certains étudiants ont calculé 45 : 20 (ou des approximations permettant d’obtenir la note maximale). D’autres ont simplifié de manière incorrecte, comme 9 : 4 ou 2 : 3, obtenant une note partielle. D’autres ont introduit un nombre négatif en établissant le ratio de façon incorrecte. La partie (c) comportait de nombreuses approches possibles qui pouvaient réussir. Nous avons également vu un certain nombre d’approches incorrectes ou inutilement lourdes, comme les quadratiques en x et en y. Certains élèves ont essayé d’adapter la formule du point médian de manière arbitraire, ou ont essayé de l’utiliser sans modification. Des étudiants ont pris F en dehors de D et de E. D’autres ont introduit des valeurs absolues dans l’équation de ratio, ce qui a donné deux solutions pour F . Certains étudiants ont fourni la réponse finale sans justification ou sans démonstration de la démarche par essais et erreurs. Il semble que certains étudiants aient oublié de tenter la partie (d). Les étudiants ont pu établir une équation correctement et une autre incorrectement. Certains étudiants ont fourni la réponse finale sans justification. Moyenne: 6,4

10 Comments on the Contests

2. La partie (a) a été très bien réussie. Les étudiants ont rencontré plus de difficultés avec les parties (b), (c), et (d). Dans certaines solutions, les étudiants ont mis en équation l’entier à deux chiffres xy avec x + y au lieu de 10x + y. Dans la partie (b), certaines solutions ont oublié d’éliminer les cas où les valeurs de x et y n’étaient pas des nombres à un chiffre. Dans les parties (b) et (c), certains étudiants ont trouvé les réponses par essais et erreurs, mais n’ont pas montré qu’il n’y avait pas d’autres solutions. Dans la partie (d), de nombreuses solutions manquaient des cas, et certaines solutions comportaient des cas supplémentaires. Moyenne: 3,6

3. Si la division était faite correctement dans la partie (a), les étudiants obtenaient généralement la bonne réponse. Dans la partie (b), certains étudiants ont tenté d’utiliser des valeurs spécifiques pour L, M, et R (en particulier les valeurs de la partie (a)), ce qui n’a pas conduit à une argumentation générale. Certains étudiants ont supposé, à tort, que les parts de chocolat devaient être des nombres entiers. Si les étudiants en déduisaient des inégalités correctes, cela conduisait généralement à un argument contradictoire réussi. La partie (c) était un problème très difficile. De nombreux étudiants ont judicieusement tenté de chercher une régularité dans le tableau, mais ils ont été trop rapidement séduits par des régularités qui n’étaient, en fait, pas vraies. Moyenne: 1,3
