bettermarks：即時フィードバックによるスマートな数学学習

For students: Math is mostly either loved or hated. No matter what your feelings are, we want to make learning math easier and to help you practice! A worksheet gives no response, so you don't know if you solved a problem correctly. With bettermarks, you always get a response, so you can learn from your mistakes.  For teachers: Use the bettermarks app to log in to the teacher portal. Browse the library with over 100,000 exercises, assign content and evaluate students' results. A license is required to use the app.
