Is the sentence correct?

Yes. "Sloths are so slow that other animals mistake them for part of a tree." is grammatically correct.

Step-by-step explanation (easy words):

  • "Sloths" is the subject. Sloths is plural, so we use the verb "are."
  • "so slow that" shows cause: it means "very slow, and because of that..."
  • "other animals mistake them for part of a tree" means other animals think the sloths are part of the tree. "Mistake X for Y" is the correct phrase.
  • "them" is correct because it refers back to "sloths" (more than one).

Small notes:

  • You do not need a comma before "that" in this sentence.
  • "part of a tree" (singular) is fine, but you could also say "parts of a tree." Both are correct.

Simple alternative sentences a 7-year-old might like:

  • "Sloths move so slowly that other animals think they're part of the tree."
  • "Sloths are so slow other animals think they're part of a tree."

Great sentence — nice job!
