Whoever comes first near the hook will be the winner! For example, if Nemo rolls the dice and it comes out 3, Nemo will go forward 3 spaces, and if the dice come out with a lesser number than earlier, they will go backward.

**Ocean-Themed Missing Numbers Finding Game**

Choose a number range. For example, you can choose numbers from 11 to 20.

- Write the sequence of numbers on a worksheet, leaving one number blank.
- Guess the missing numbers.
- For example 11, 12, _, 14. They will guess and write the correct answer. The answer is 13.

**Color By Number: Ocean Animals**

This activity is centered around ‘**coloring this crab**‘.

- First look at the drawing of the crab. There are some numbers written all over it.
- For each number, there is a color code mentioned in the paper.
- Here comes the most fun part! Color the crab according to the color code. For example, I want to color the eyes of the crab. To do that, I need to know the number which is ‘1”. Now I will look for the color for number 1. And it is white as given in the paper. So I will give the eyes a fine white shade.

**Count the Fish and Release Them for Ocean Themed Math Activities**

Draw some fish.

Color the fish red, yellow, green, blue, orange, etc.

Then, give them a worksheet where the ocean is drawn.

After that, choose a task card where the number of fish is written and put them in the ocean.

For example, if they choose 5 fish to put in the ocean, they will take 5 fish and put them in the ocean to live.

**Ocean-Themed Counting Pirates Board Game**

First, make a worksheet where boxes will contain pirate ships, maps, birds, hats, flags, etc. Some boxes will be crossed.

They also need dice to roll. When the game starts, the students roll the dice serially.

If the dice roll on a cross, they will get nothing and can’t come forward from the previous place, and if it rolls on treasure, they will get a point and come forward.

Whoever arrives at the endpoint first will be the winner. For example, when a student rolls the dice on the ship, she comes forward and gets a point.

But if the dice roll on the cross, she can’t move from the previous place and will get nothing.

**Finding the Octopus’s Lost Arms for Ocean-Themed Math Activities**

Octopuses are famous for their eight arms. This worksheet provides subtraction problems.

For example, if I draw an octopus with five arms and tell my child that an octopus has eight legs but I only draw three of them, then how many of the legs are lost? After that, they subtract 8 from 3 and say that the octopus lost five of its arms.

**Ocean-Themed Patterning Math Activity**

Set up a challenging pattern. For example, I bought many stickers of octopuses, starfish, sea snails, clownfish, etc. Then, I make a pattern of ABA, where the octopus and the sea snail are A, and the clownfish and the starfish are B.

Now, I stick the octopus, clownfish, and octopus in the first row, and then the sea snail, starfish, and sea snail in the second row. Now the children will make a pattern, which is ABB.

**Ocean Number Game**

Take a worksheet and divide the sheet into two parts.

- Draw some ocean fish on one part.
- Write some random numbers on the animals and also on the other parts. Here we used 1-20 numbers.
- Ask the students to cut the numbers and stick them beside the right pictures.
- For example, if they chose a fish with the number 12, they will cut the number 12 and stick it beside the right photo.

**Ocean-Themed Graphing Activity**

Need a cube dice on which the photos of a starfish, an octopus, a sea snail, a shark, a clownfish, and a crab are drawn. Also provide a worksheet where students can record the numbers. There are 15 columns, and each time students roll the dice, they record their rolls.

When a student rolls the dice and the octopus appears five times, she might mark column 5 on the worksheet.
