This easy worksheet shows second graders that big words can be two little words shaking hands. Part A sorts six words including airplane, backyard, and campfire into 'Compound Word' or 'Not a Compound Word' piles, with tricky non-compounds like market, silver, and garden mixed in. Part B has five fill-in-the-blanks that build words such as back + yard = backyard and break campfire into camp and fire. Part C wraps up with four true-or-false statements that check whether airplane really is a compound and whether a compound always has three parts.

By the end, students can spot the two-word pattern and decode new compounds with confidence.
