The Olympics is profound and complicated. This is not a question of brain teasers or cleverness. It is the extension and expansion of mathematical knowledge. The first-grade children don't even know anything about Olympic mathematics. A more scientific suggestion is to start learning the Olympiad from the third grade, and the Olympiad in the third grade is basically based on simple calculation and divergent thinking. In the fourth and fifth grades, after learning new mathematics knowledge, Olympic mathematics learning will also add new knowledge points accordingly!
Now the most suitable stage is the enlightenment education of mathematical thinking!
It will be more convenient to learn Olympic Mathematics when children's thinking ability is improved!
You can learn about the spark thinking in China, and it is more professional here, so that children can participate in the next course!
