This easy worksheet introduces second graders to the difference between common nouns and proper nouns through three friendly sections. In Part A, kids sort six words such as river, Amazon, Friday, and Canada into Common Noun and Proper Noun boxes. Part B uses fill-in-the-blank sentences to explain why lake is common but Friday is proper, and reminds students that proper nouns always start with a capital letter.

Part C wraps up with true-or-false statements about Saturday, mountain, and country names. Sorting first, then writing, then judging gives second graders three different ways to lock in the rule, so capitalizing names becomes automatic in their own writing.
