我以前都不知道有AMC这个竞赛,只知道五、六年级的学生会参加一个Australian Problem Solving Maths Olym ...
的确很赞同你的看法。只是一个培养孩子对数学兴趣的渠道和方式而已。
UNSW 有 ICAS 竞赛,
ANU 有 AMC
Melbourne University 有墨大的数学竞赛。
这些都是为了提高孩子对数学的兴趣而设计的考试。当然,在考试的过程中顺便发现些真正有天赋的孩子。
对于 AMC, 前面10道题目相对地简单。
比如 2015 年的 Upper Primary
1: What does the digit 1 in 2015 represent?
(A) one (B) ten (C) one hundred (D) one thousand (E) ten thousand
2:What is the value of 10 twenty-cent coins?
(A) $1 (B) $2 (C) $5 (D) $20 (E) $50
从 11 到20题有个别的题目有点难度,但是如果孩子稍微努力下,大多数题目应该都能做对。
21~ 25 有点难度了。
25. Eve has $400 in Australian notes in her wallet, in a mixture of 5, 10, 20 and 50 dollar notes.
As a surprise, Viv opens Eve’s wallet and replaces every note with the next larger note. So, each $5 note is replaced by a $10 note, each $10 note is replaced by a $20 note, each $20 note is replaced by a $50 note and each $50 note is replaced by a $100 note.
Eve discovers that she now has $900. How much of this new total is in $50 notes?
(A) $50 (B) $100 (C) $200 (D) $300 (E) $500
最后 5题可能难度会比较大些(非选择题)
29. A 3×2 flag is divided into six squares, as shown.
Each square is to be coloured green or blue, so that every square shares at least one edge with another square of the same colour.
In how many different ways can this be done?
有些年度的题目,如果孩子会些代数的技巧,可能会容易“猜出”答案来(不需要过程)。
这类考试,只是众多考试中的一种。考好了,天上不会天天掉馅饼,考不好了,天上也不会时时砸陨石。没有必要大惊小怪的了。 |
