I would like to offer a free online teaching and learning tool (www.esllearningtools.com) for you.
It's an online flash card system that helps you interact with students. Teachers and students can participate in creating flash cards under any projects that they created after they are connected. If you are a student and not having any teachers to work with, you can simply sign up and create your own flash cards to study.
It's a lot of fun and easy for students and teachers to use. It works perfectly on any mobile devices. I can guarantee that you and your students would have fun playing around with it.
Please feel free to recommend it to your students/teachers and friends. The website is www.esllearningtools.com If you have any questions, please feel free to email me at firstname.lastname@example.org. I would be happy to assist you.
