A 100th day of school parent letter you can send today

Six details prevent most of the questions: the date, the 100-item collection and how to display it, the dress-up or shirt plan, the snack and allergy rule, how much help is appropriate, and how the project travels to school. Add a sentence about cost: the project should use things from home, not a shopping list. Add a sentence about original work if costumes are allowed. Keep the tone friendly. Families are counting 100 tiny objects on a school schedule; a clear note respects their time.

Replace the bracketed parts and send. The letter is plain text, so it works in an email, a newsletter or a printed handout.

Dear Families,

Our class is celebrating the 100th day of school on [date]. We have been counting since the first day.

What comes home: a 10×10 chart for the 100 things project. Your child chooses 100 small items, counts them in ten groups of ten and brings them to school on the chart or in a labeled bag. Ideas: cereal, buttons, stickers, pennies, pom-poms, paper clips, LEGO bricks or 100 words. Please use things you already have; no need to buy anything.

What to wear: dress like you are 100, wear school colors or a 100th day shirt. Everything is optional. A cardigan, glasses or a school shirt is plenty.

Snack: we will make a 100-piece snack and count ten groups of ten. If your child has a food allergy, send a safe snack from home; we will use a separate mat. Our classroom is [nut-free / allergy-aware].

How to help: let your child choose the collection and do the counting. Adults may help with printing, cutting, glue and transport. The idea and the sentence should be your child's.

Return: the collection and the sentence by [date]. We will display the projects and celebrate with a parade and a certificate.

Thank you for helping us count to 100.

Sincerely,
[Teacher name]
[Room number or contact]

If the first letter is already out and you need a nudge, send this: 'A reminder that our 100th day celebration is [date]. Please send the 100-item collection on its chart or in a labeled bag, and have your child wear school colors or a simple 100-year-old costume if they would like to. Everything is optional and can come from home. Thank you!' Short sentences, one date, no new rules. Short reminders get read.

For kindergarten, ask for one sentence and offer to help with the counting; suggest large items such as cotton balls or pom-poms. For first grade, ask for the 10×10 chart and one sentence. For second grade, add a short written explanation: what the collection is, how it was counted and one thing the child noticed. If your class is doing a shirt, say so and give the no-sew methods. If the class is collecting food for a shelter, say which items are welcome and which are not.

For email, use a subject such as '100th Day Celebration, [date]' or '100 Things Project, due [date].' Paste the letter into the body; more families read it on a phone. Send it two weeks ahead, then a one-line reminder three days before. If you use a class app, post the same text and pin it. For paper, print the letter on one side and the chart on the other, or staple the note to a folder. A half-sheet reminder is easier to find than a full page.

Three equity traps: a costume that requires a purchase, a snack that excludes a child with allergies and a collection that requires a trip to the store. Close all three in the letter. Offer a school-color shirt instead. State the allergy rule and offer a safe snack from home. Give a no-shopping list of collection ideas and a no-food alternative. If the class is taking photos, say so and let families opt out. The 100th day should be a day every child can join, not a test of what a family can buy.
