I think it is necessary to enroll children in the Olympics class, depending on their learning ability, academic performance and enthusiasm for learning. If children's learning enthusiasm is not very high, and their academic performance is not very good, then there is no need to enroll children in various Olympic math classes, because Olympic math has nothing to do with our math learning, but to cultivate children's math learning thinking in the process of learning Olympic math, so that children's thinking patterns when facing math problems become clearer. Because these enthusiasm and academic achievements are not very good, children will certainly not have amazing talent in learning Olympic mathematics.
If children's academic performance has been excellent, and they are also very active in solving some math problems, then children can be encouraged to think about math learning in the process of learning Olympic Mathematics. Because learning math well is not a way to improve children's academic performance, but a way to make children's academic performance icing on the cake. If the child's academic performance is excellent, it shows that the child has mastered mathematics knowledge in primary school, so learning Olympic Mathematics can better stimulate the child's thinking ability about mathematics learning.
So, do you need to sign up for the Olympic math remedial class for your child? You need to look at your child's learning ability and academic performance. Don't blindly enroll your child in various classes, because this will not only not improve your child's academic performance in a short time, but will create more burdens and troubles for your child.
