Van a cantar mucho en la fiesta. Proper?

Question

I am working on my lesson and I was to follow these directions for the WRITE test.

Change each of these simple present sentences into the informal future using Ir + a + infinitive. 1. Como pizza en el restaurante. 2. Celebramos mi cumpleaños.
3. Cantan mucho en la fiesta.

For number 3, I put it this way......Van a cantar mucho en la fiesta.

When I looked at other lessons that were submitted, I saw that they left (mucho) out. Was leaving it in proper? Or is how I typed it proper. And if not, why'

Answer 1

Thank you very much.

Since the exercise is to recast the sentence in the future, the "mucho" should be there in both sentences. Dropping the "mucho" isn't grammatically incorrect but it does change the meaning somewhat. "We're going to sing at the party" vs "We're going to sing a lot at the party"
