Grammar check for a 7-year-old: “The pigeon speaks in low, soft coos.” and “All the animal friends are glad to join in the chorus.”

Both sentences are grammatically correct. Here is a simple, step-by-step explanation so a 7-year-old can understand why:

1. Sentence 1: The pigeon speaks in low, soft coos.
   
   • Subject: "The pigeon" (one bird).
   • Verb: "speaks" (what the pigeon does). Because the subject is one pigeon, the verb has an -s: "speaks."
   • Phrase: "in low, soft coos" tells how the pigeon speaks. "low" and "soft" are two adjectives describing the coos. We put a comma between them because they are two equal adjectives (you could say "low and soft coos").
   • Word choice: "coos" is the sound pigeons make, and it is correct to use it here.
2. Sentence 2: All the animal friends are glad to join in the chorus.
   
   • Subject: "All the animal friends" (more than one friend).
   • Verb: "are" (used because the subject is plural).
   • Phrase: "glad to join in the chorus" tells how they feel and what they will do. "Join in the chorus" means they will sing together.

Small style ideas (not corrections, just different ways to say the same thing):

• "The pigeon coos softly." (shorter and still correct)
• "All the animal friends happily join the chorus." (another way to say the second sentence)

Good job — your sentences are clear and correct!
