Practice number-and-quantity skills for school entrance prep with cute animal-themed activities. Compare, count, order, and share across 7 playful categories.

“Ojuken Kazu & Ryo Master” is an educational app designed to help children practice essential number-and-quantity skills often seen in elementary school entrance exams.

With friendly animal characters, soft colors, and easy-to-understand visual questions, children can learn through play while building a strong foundation in early math thinking. Instead of relying only on text or formulas, the app encourages children to look, tap, compare, count, and think step by step.

The app includes 7 core learning categories:

・Bigger or smaller ・Ordinal position ・Find the same quantity ・Increase and decrease ・Sharing equally ・More and less ・Order and sequence

Each category includes multiple difficulty levels, making it easy to start simple and gradually move to more challenging questions as confidence grows.
