The Kangaroo Math Kangaroo is the world's largest mathematics competition for teenagers, held annually in 87 countries and territories and attended by more than 6.3 million teenagers worldwide. Learn about Math Kangaroo, the world's largest kangaroo math competition!

What is the Kangaroo Math Contest

The Kangaroo Math Competition was initiated in 1980 by the famous Australian mathematician Peter O'Halloran. In 1991, two famous French mathematics educators established the official competition organizing committee and promoted the competition in Europe, in order to pay tribute to Peter O'Halloran, the competition was officially named "Kangaroo Mathematics Competition". The Math Kangaroo Kangaroo Math Competition is one of the world's largest youth math competitions for students in grades 1-12.

Traditional mathematical powers such as Russia and Germany have about 1 million teenagers each year, France, Brazil, the Czech Republic, Poland and other countries have more than 300,000 teenagers each year, and Spain, Austria, the Netherlands, Sweden and other countries have more than 100,000 teenagers.

Kangaroo Math Competition has been held in the United States for more than 20 years, and the number of participants is increasing rapidly every year, especially in California, where the Asian population is large, the kangaroo math test is difficult to find every year! In 2021, more than 58,000 Chinese students participated in the Kangaroo Mathematical Thinking Challenge.

Kangaroo Mathematics International Competition questions are more interesting than other math competition questions, for children is also a good opportunity to practice, as long as serious participation, the probability of winning is still very high, the top 35% of the national ranking can win the prize, in addition to the top 20% of the divisions also have mathematical skills awards. Online exams are also very convenient, and you can participate in such a high-gold international event without leaving your home!

Let's take a look at math Kangaroo's title.

01

Reading comprehension

To practice mathematical thinking, you must first strengthen reading comprehension.

Let's look at the following question, this is the 1st and 2nd grade questions, you let the child read it to see if you can understand the problem?

The first time I looked at this topic, I was a little confused, and then I looked at the topic and looked at the pattern carefully, only to find that there were dots on each ladybug, and the number of dots was also different, so the text emphasized a sentence "in the order of increasing number of dots", you must understand this sentence, in order to understand the need to connect the ladybugs according to the number of dots. The answer to this question is D.

If you can't read the problem, the child's mathematical calculation ability is useless!

02

Visual perception

Visual training is also very important, first to capture the image, then to analyze the image, and to restore the image in the brain. Especially for the plane geometry and three-dimensional geometry in mathematics, this is completely a manifestation of visual perception ability.

Look at the following visual training questions for grades 1 and 2 and ask what an image color will look like when you swap colors.

The answer is E.

When it comes to the 3rd and 4th grades, it is still the same pattern, but it is more difficult for children to think. If you look at the following question, not only does it require the child to swap colors, but also to rotate the image and ask what it will look like in the end?

The answer is E.

03

Mathematical modeling skills

Let's look at the following 3rd and 4th grade questions, there are 4 balls, which are 10g, 20g, 30g and 40g, according to the balance instructions in the figure, ask which ball is 30g?

This problem requires the child to be able to build a mathematical model according to the image, otherwise this problem TA cannot do it! This mathematical model should look like this:

The first model is: A+B > C+D, which corresponds to the first diagram showing that the weight of A and B is heavier than the weight of C and D.

The second model is: B+D = C. This corresponds to the second figure, which shows that B and D weigh as much as C.

With these two models, it is easier for children to bring in the numbers and get the answers! The answer is C.
