Is this sentence correct? I sat down with him and helped him with the layers of the earth worksheet. Or do I need to take out the before layers
Your sentence is correct -- "the layers of earth worksheet."
You could eliminate the words "with him."
Ok thank you
You're welcome.
The sentence "I sat down with him and helped him with the layers of the earth worksheet" is grammatically correct as it is. The use of "the" before "layers" is appropriate if there is a specific worksheet that both you and the person you're talking about are referring to.
To determine whether or not "the" should be used, consider the context. If you are referring to a particular worksheet that you both have in mind, it's appropriate to use "the." However, if you're talking in a general sense, and not referring to a specific worksheet, it would be more appropriate to remove "the" and say "the layers of the earth worksheet" instead.
