Something we talk about a lot when writing is adding detail. Thinking about the senses is always a great place to start because most students are familiar with how things look, feel, smell, taste and sound, as applicable. I asked each student to choose a food photo from the iPad's photo album and write about 4 of the senses (we skipped sound since for some foods this is difficult).
I asked first grade students to use the Popplet app and write the senses in different bubbles. I asked the second grade students to use the StoryBuddy app and write complete sentences.
