There is no one-size-fits-all answer to this question, as the appropriate age to start pushing a child towards Math Olympiads will depend on a variety of factors, including the child's individual abilities and interests, their previous exposure to mathematics, and their level of motivation.

However, generally speaking, children who have a strong interest in mathematics and have demonstrated an aptitude for the subject may benefit from participating in Math Olympiads at a young age. Some children may show an interest and aptitude for math as early as primary school, while others may not discover a passion for the subject until later on.

It is important to note that while participating in Math Olympiads can be an enriching and rewarding experience for many children, it is not necessarily the right choice for every child. Parents should carefully consider their child's individual needs and interests before pushing them towards any particular activity or program.

Additionally, it is important to ensure that children have a balanced and well-rounded education that includes opportunities to develop their social, emotional, and physical skills, in addition to their academic abilities. Pushing a child too hard in one area can lead to burnout or a lack of interest in the subject.

Ultimately, the decision to push a child towards Math Olympiads should be based on a thoughtful consideration of the child's needs, interests, and abilities, as well as a commitment to providing them with a well-rounded education.
