Books about the Ocean

Reading books together is my favorite part of homeschooling! Children learn so much from picture books and it’s an excellent way to spend quality time passing on a love of reading to your kids. You can learn a lot about the ocean from some of our favorite books. 

Explore ocean habitats with Ms. Frizzle in The Magic Schoolbus on the Ocean Floor. Discover the beauty of the reef with this artistic picture book delight: Over in the Ocean in the Coral Reef. Meet ocean animals while exploring the art of collage in Eric Carle’s Mister Seahorse

When kids use their fingers to manipulate materials, they build fine motor skills essential for lots of daily tasks and handwriting.

Adding an art project to your under the sea study is an excellent way to add learning and creative fun to lessons. Art helps kids practice critical thinking skills and learn about the relationship between cause and effect. It also provides opportunities to learn about patterns, an essential early math concept. 

Creating under the sea art together is a fun way to explore the ocean with your kids.

Under the Sea Games

Do you think the fish play games under the sea? You can pretend to swim around like fish with your kids, in the pool, or even in your living room. As you swim, play a game of undersea tag. Instead of “it,” pretend to be a shark and swim around looking for fish. 

My kids love a silly game I invented one night at a hotel pool. I was too tired to want to get in the water, so I sat by the pool watching them swim. Periodically, I called out “Shark in the water!” and begin to count. My children would squeal and swim to the steps. If they made it to the steps before I made it to 10, they were safe. It entertained them for half an hour and they still beg to play whenever we go swimming. 

As you can see, under the sea themed games are some of my favorites! Playing games together is a fun way to spend quality time that’s full of learning and (at least in our house) laughter. Games teach kids important life skills too, like how to wait for their turn and be a good sport. 

We like learning games like letter matching with seashells, shark memory, and under the sea bingo. Learn how to play these games and lots of other fun ocean games with your little ones.
