My students used the app Feltboard to write speech bubbles for the stuffed animals they brought in from home. I share out 1 or 2 projects each unit using padlet, so students can read one another's work and families can read their writing as well. Padlet is free when you sign up, and although Feltboard is not, this is a really efficient and accessible way to boost student's writing by augmenting their audience.
Please check out our work here, and more will come next week!
