There are many educational methods that can help 2-year-old children improve their memory. Here are some ways:

1. Use games: let children learn while playing, and remember while playing, such as the game of "You shoot one, I shoot one".

2. Cultivate children's concentration: children are inattentive and half-hearted, and their mastery of knowledge is naturally unstable. Therefore, improving children's memory and cultivating children's study habits of concentration are the first conditions.

3. Read more books: Reading can help children improve their memory and language skills.
