I do a variation of Show and Tell in my first grade class called Share Day. The first day of school I bring a family picture and briefly talk about it. I invite the children to ask questions and remind them that questions start with who, what, why, when, where, and how. I send home a letter to the parents explaining this activity, the kinds of things children can share (stuffed animal, awards, family pics, a favorite song, a joke, etc.) and the day their child will be asked to share. The students enjoy this chance to learn more about each other, and I enjoy watching them hone their communication skills.
