C2M J
Why C2M J?
It is a re-established math program built upon C2M Edu's strengths in manipulatives and curriculum, designed with the hope that through fun games and activities, children will discover mathematical concepts and principles on their own and grow up with the ability to see the world through the lens of mathematics.
Core Point
Develops Thinking Power
Infants and children can easily understand mathematical concepts by manipulating the manipulatives.
Motivation
Through fun class processes, they can naturally immerse themselves and expand their mathematical curiosity.
Learning Value
We present an active learning model designed to enable learning through learner-centered natural play activities.
Self-Directed
Mathematical thinking skills can be developed through the process of solving problems on their own.
Introduction

Learning Kit Components

J1 Numbers
Ordering numbers, reading numbers in different ways, comparing numbers, and completing number sentences.

J2 Solid
Matching identical shapes, stacking blocks, counting unit cubes, identifying top, front, and side views, matching silhouettes seen from different directions, and building 3D shapes from silhouettes.

J3 Make Number
Ordering numbers up to 100, skip counting, finding products, making 10, connecting paths, solving nonograms and Sudoku, moving coins, building correct equations with matchsticks, and playing Nim.

J4 Shapes
Tangram, wave, and pentomino puzzles, filling in shapes, identifying symmetry, creating reflections, and constructing polygons.

J5 Pattern Line
Identifying attributes, completing attribute matrices, creating patterns, discovering rules in pattern cards, and recognizing analogies.

J6 Measure Kit
Reading and showing time, comparing and estimating length, estimating weight, and making calendars.

J7 Geoflick
Building prisms and pyramids, constructing cubes, working out how many GEOFLICK pieces a shape needs, identifying nets, and creating original shapes.

J8 Treasure
Extra manipulatives that make games more dynamic and fun.

- Levels
- S (Age 5), P (Age 6), A (Age 7), B (Age 8)
- Composition
- Units 1–12 · 48 books in total
- Features
- Five learning areas · A complete four-week program in each volume
From Early Childhood to Primary Math
Bridging Korea's national early-childhood and primary curricula, the program is organized by level (ages 5–8) and five learning areas: numbers; operations and strategies; 2D and 3D shapes; attributes and reasoning; and measurement and statistics. Each volume is a self-contained four-week program.
Unit Learning

Talk
- Open-ended scenarios and everyday stories introduce each unit's theme, sparking curiosity and drawing children naturally into mathematical thinking.

Concept
- Explains the essential concepts students need to grasp in each unit.
- Checks understanding of the key concepts with simple questions.

Act
- Introduces the unit's theme through simple, hands-on activities. Students get first-hand practice with the unit's key manipulative here, so they enter the Play section already confident using it.

Play
- Games with manipulatives deepen both interest and understanding. Explored through play, math becomes something children choose, not something they endure.
- Exploring each theme through games helps students enjoy learning math even more.

Mission
- A broader set of questions extends the unit's theme. With stickers and manipulatives throughout, children stay active — doing, not just answering.
Digital Teaching Aid
Web-based activities make C2M J content accessible anytime, anywhere. Organized by level and week, they work equally well for practice at home and as ready-made support in the classroom.
