The best way for kids to learn is simply by letting them make mistakes, every time a student makes a mistake, they will remember the correct method to get the answer the next time. This means more practice.
During my class I use digital technology such as google classroom to teach my students which provides my students with a digital workspace.
I love to make my students feel comfortable by letting them listen to music while learning (most students prefer to listen to music whilst learning) as well as making jokes and having an overall fun and friendly experience, the student should feel like they are learning from a friend as opposed to a boring old teacher.
