I enjoy having conversations on a range of topics and it gives me a sense of accomplishment when my students get better at reading, writing, listening and speaking skills. Learning English does not have to be uninteresting and I am sure we can find something we have in common and strike a balance between fun and learning.
I usually play games with young children to practice a new language and use worksheets to further reinforce what they have studied.
Let us keep it simple and have fun!
