This challenging worksheet pushes first graders into multiple choice and fill-in-the-blank reasoning about common and proper nouns. Part A asks them to pick the proper noun from sets like 'park, dog, Denver, tree,' identify the common noun in 'Bella, Texas, garden, Mr. Kim,' and choose the sentence that uses a proper noun correctly ('My friend is Mia.'). Part B has them complete sentences using 'Florida,' 'pencil,' and 'Mrs. Grant,' and recall that proper nouns need a capital letter at the start. The format trains students to compare options and apply the rule under pressure.
