This Grade 1 moon phases worksheet guides first graders through the four main phases: full, half, crescent, and new moon. Nine fill-in sentences describe each shape and the monthly pattern, and a matching activity links phase names to simple picture clues. Grade 1 kids learn that the moon itself is always round, but the bright part we see changes in a repeating pattern.
