Answer:
The students of first grade open their interactive notebooks at 10 o'clock everyday.
Step-by-step explanation:
Before making a sentence that includes a common noun and a compound common noun, we must know what these types of nouns are. A common noun is one that name persons, places, things or animals in a general way, thus, they are not capitalized unless they begin a sentence or are part of a title, for example, music, castle, diamond, mint, finger, animal, person, thing.
On the other hand, a compound common noun is a common noun that consists of two or more words; they can be written as one word like breakfast, as two or more words such as washing machine or with a hyphen like lamp-post.
The sentence provided has three common nouns: students, grade and notebooks, and one compound common noun: notebooks (note + books).
