I'm an english teacher, which technics can I use for a group of children 5-9 years old?

u sould probaly use differnt websites like isafe and chat logs to teach them howto be safe online! like I did that when was that age and I was still doing it all though 3 grade to middle school!

Try distar. I remember growing up and my preschool teacher who I'm still cool with to this day using it on us. I just googled it and its still available.
