How to improve the level of knowledge in mathematics?

Hey everyone, my son recently started second grade and is having trouble with math. At first, he tried to learn it himself, but he was very bad at it. Can you please advise how to solve this problem?

Hello, my daughter had the same problem and it is solved quite easily. The second class is banal knowledge on this subject that any child can master, the main thing is to present this knowledge correctly, and the math 2nd grade course can help with this. These are free lessons that are very well structured, which makes them a good replacement for any teacher. I think this is exactly what you need.
