Why Learning the Letter O Matters

Learning the letter O helps children build important early reading and writing skills. As preschoolers practice tracing and recognizing the letter O, they begin connecting letters with sounds and strengthening alphabet knowledge.
Children practicing the letter O are strengthening:
Letter recognition
Beginning sound awareness
Fine motor development

Practice saying “O says /ō/” together for the word ocean.
Point to uppercase O and lowercase o.
Talk about ocean animals and places your child may have visited such as beaches, lakes, or aquariums.
