Fish Cracker Math


Crab Walk

[Large Motor]
Children crawl like a crab from one point to another. Next, they have to figure out a way to carry a bean bag while crawling like a crab.

Sea Shell Prints

[Fine Motor Skills]
Children use seashells in the play dough area to press into the play dough to make prints. You can do the same activity using self hardening clay and the children can keep them.

Pre-K Ocean Theme

Colored Tape Fish

Children draw their own fish on a piece of paper. They tear off pieces of colored masking tape and stick them on for the fish’s gills.

Pre-K Ocean Theme

Wax Resist

Children draw an ocean scene or one ocean animal with oil pastels. They paint over the whole paper with blue watercolor paint to create the water. The wax in the oil pastels resists the water, so the picture shows through the paint.

Pre-K Ocean Theme

Sea Salt Art

The children mix their own salt paint, and then paint a picture of an ocean animal.

Salt paint recipe:
2 tsp. Salt
1 tsp. Liquid starch
Few drops of food coloring

Mix ingredients together. The salt gives a frosted or sandy appearance to the paint.

Pre-K Ocean Theme

Fishing Game

Our “ocean” is a blue shower liner on the floor. Paper fish have 0-10 dots on them, with a paperclip attached, and are tossed onto the “ocean”. Children catch a fish with magnetic fishing pole, count the dots on the fish, and write or stamp the numeral on a fish cutout. The magnetic fishing poles were made with a magnet wand tied to a rhythm stick with string.

Pre-K Ocean Theme

Fish Flop

Children use spray-painted beans (one side yellow, one side blue) as pretend fish. Ten fish are placed in each child’s cup. The children dump the cup onto the table and count to see how many fish flopped on the blue side and how many flopped on the yellow side.

Tuna Fish Sandwich

With this snack, we get to taste something that comes from the sea. We use a fish cookie cutter to cut two pieces of bread. We make tuna salad by adding mayonnaise and sweet pickles to a drained can of tuna. Then, spread the tuna on the sandwich.

Ocean Snack

We place three vanilla wafers in a ziplock bag and crush them to make sand. We pour the sand in the bottom of a clear cup, and scoop blue Jello on top. Last, we add gummy fish.

Pre-K Ocean Theme

Wave Bottles

Children use a funnel to pour a cup full of baby oil (or cooking oil) into a clear plastic bottle. They fill the bottle the rest of the way with water. We give the liquid a chance to settle, then add a few drops of blue food coloring. It’s fun to watch the blue as it drops through the oil and “explodes” into the water. Last, we add plastic “fish” (sequins), and make waves by turning the bottle sideways and rocking it gently.

Pre-K Ocean Theme

Float & Sink

children work in pairs to test the items (cap, penny, marble, feather, toy fish, Unifix cube, etc.) in the water. Each child gets their own item to test in the water, but each pair shares a tub of water. Before handing out each item, I ask them to make a prediction whether they think the item will float or sink. Then, we check our predictions to see which ones we guessed correctly.

Pre-K Sensory Table

Boats (Exploring Density)

[Sensory Table]
Children start with a ball of clay, which sinks in the water. They form the clay into a boat that will float. After they have made a boat that floats, they add small bear counters to see how many can sit in the boat without it sinking. Note: Only use oil-based, non-hardening modeling clay for this activity. Do not use play dough or earthenware clays.
