Title: My friend went to my house.

"My friend went to my house today.
We played a board game and watched TV. Then, we went to the playground.
After that, we went to the mart next to the playground and bought snacks.
I bought some snacks, and my friend bought jelly.
I want to play with my friend again!"

Explanation:

1. "My friend went my house today." → "My friend went to my house today."

• Error: Missing preposition ("to").
• Why? In English, when using the verb "go" or "went" (past tense of go), we need "to" before a destination.

"We play a board game and watch TV." → "We played a board game and watched TV."

• Error: Mixed verb tenses.
• Why? Since the first sentence uses "went" (past tense), the rest of the events should also be in past tense.
• "Play" → "Played" and "Watch" → "Watched" to match past tense.

3. "And we go to playground." → "Then, we went to the playground."

• Errors:
  1. "Go" should be "went" (past tense).
  2. Missing article ("the") before "playground."
  3. "And" is not the best transition here. "Then" sounds more natural.

4. "We went to the mart next to the playground and bought snacks."

• No error! This sentence is already correct. Great job! 

5. "I bought a some snacks and my friend bought jelly." → "I bought some snacks, and my friend bought jelly."

• Error: "a some snacks" is incorrect because "a" and "some" cannot be used together.
• Why?
  • "A" is used for singular nouns (e.g., "a snack").
  • "Some" is used for plural nouns (e.g., "some snacks").

6. "I want to play with my friend again!"

• No error!  This sentence is already correct and natural. Great work!
