Draw a large capital O on light blue construction paper. The O should be thick enough to decorate. Cut out the letter carefully.

For younger children, pre-cut the letter O in advance. Older preschoolers and kindergarten students may practice cutting along the lines for added fine motor skill development.

Using a dark blue marker, draw curved lines across the surface of the O to resemble ocean waves. The lines can vary in size and spacing to create a layered water effect.

Encourage children to move the marker in smooth, curved motions. This builds hand control and coordination while also functioning as an ocean themed craft.

On different colors of construction paper, draw simple fish shapes. Oval bodies with triangle tails work well and are easy to cut.

Cut out several fish in various colors. This step strengthens scissor skills and allows children to experiment with shape and color choices.

Use a marker to draw eyes and smiles on each fish. Choose a darker shade of the fish’s color, or a complementary darker color. Red on an orange fish, dark green on light green, etc.

Discuss fish features such as scales, tails, and gills to introduce new vocabulary during this ocean craft for kids.

Arrange the fish around the letter O as though they are swimming through the waves. Glue each in place once satisfied with the layout.

Allow the glue to dry completely before displaying the finished project.
