In my classroom each student is assigned a classroom number. Every month each student will have the opportunity to bring in a "share item" for show-and-tell and/or a snack to share with his friends on his number date. For example, Sam's classroom number is the number 10. Therefore, every month Sam's share day will be on the 10th of each month. The only time his share date will be different is when his number falls on a weekend, holiday, or another friends birthday. Share is not required and you may choose for your child not to participate.
