"I see! Math for 1st Graders" I see! Math 1 is a full-fledged learning app that adheres to the Japanese Ministry of Education, Culture, Sports, Science and Technology's curriculum guidelines. It covers all math units (25 units, 50 sections) that first graders learn in a year. It's comprised of interactive explanation sections, where you can learn all units enjoyably with full animation and full voice, and problem-solving practice sections to solidify academic skills. Bilingual Learning Experience The app seamlessly switches between English and Japanese. We meticulously focused on native expressions and native voices to ensure children can learn math naturally in either language. Even the humor is designed in consultation with native speakers. To accommodate environments like classrooms where sound isn't always an option, all animations come with subtitles ( English and Japanese). "Let's See!" Corner: Cute characters come to life through vivid animations, teaching math concepts clearly and stimulating curiosity through engaging stories. Kids even interact with the movies at times! Everyone gets absorbed in the humor-filled storylines. We often hear from children about their favorite characters! "Practice" Drill Corner: With abundant hints, children experience the satisfaction of solving problems independently, steadily deepening their understanding from basic to advanced concepts. Safe and Secure Design: The app has absolutely no in-app purchases, ads, or links to external sites. We don't collect personal information, nor do we provide it to third parties. We provide an environment where your child can learn safely and confidently on their own. Highly Trusted by Educators: This app has been widely adopted in general elementary schools, and notably, many educational boards and schools have introduced it in support classes for truancy and special needs classes. It transforms often dry learning content into engaging, humor-infused stories. Contents: How Many? (1) How Many? (2) How Many? (3) Which One? Parts and Whole Find the Part How Many are Hiding?
