中学受験用アプリ とけますかね~? 算数版の紹介
This is a problem collection that introduces problems and techniques that people who aim for middle school or higher should definitely know. If you know it before the sixth grade, you will know the academic ability you should aim for. Let's do our best for about 3 months with one question a day as a guide. If you don't understand a problem, ask an adult close to you! Focus on understanding how to solve.
