Five subtraction problems run down the page, each inside its own color-coded rounded rectangle. Every row asks ‘How many are left?’ and shows a group of kawaii sea creatures on the left, a smaller ‘Take away’ box in the middle, and a large dashed answer box on the right. Subjects across the five problems are colorful fish, red crabs, multicolored starfish, more fish in different colors, and pastel seashells. A cheerful dolphin and turtle decorate the header alongside the bold ‘Ocean Subtraction’ title.

Kids count the starting group, count what is being removed, and write or draw their answer in the generous dashed box. The answer boxes are large enough for young writers still forming numerals, and the visual groupings make it easy to check work by counting remaining images. Part of the Homeschool collection, this sheet works well tucked into a morning math folder or used as a quick review alongside a counting unit.
