In the past I have had kids use Kidblog but I don't want to pay for it. One year we used SeeSaw. It was easy and worked well. There is just a lot of scrolling. I think my students will take writing for a blog more seriously if it doesn't look like Facebook or Snapchat. So I really like weebly edu. It's free and each student has their own space. To finish out this year, I'll stick to easy- and use Seesaw.
