This is the time of year when teachers across the nation begin to prepare for the 100th day of school. In my classroom, the 100th day is quite an event. It is a day filled with activities all centered on the guest of honor: the number 100.

From the very first day of school, our class began keeping track of the number of days we have been in school. As part of our morning calendar routine, we add one popsicle stick to our hundreds pocket chart, then count our sticks. Blue sticks are equal to 10, and red sticks are equal to 1. This daily routine is setting the foundation for learning place value. On our hundreds chart, we move the clip over one number each day. Then the helper of the day uses the special pointer to lead the class in counting.

As we approach the end of the chart, the students realize that we are getting very close to the hundredth day of school. Somewhere around day 80, we begin counting how many days we have left until the big day.

Before the Big Day

To prepare for our festivities, I ask a few of my faithful parent volunteers to assist at our stations during the day. Once I know how many helpers I will have, I make my list of 100th day activities and begin collecting the supplies.

This year we will rotate through six stations, completing the following:

• Necklaces with 100 Froot Loops
• 100th day hats
• A class banner that reads “I Am 100 Days Smarter”
• Writing on the theme of "If I had $100 . . . "
• 100th day glasses available from Scholastic Printables
• 100th day trail mix. You will need one small, resealable zipper storage bag and enough of the following items for each student: pretzels, three types of cereal, fish-shaped crackers, mini marshmallows,
 chocolate chips, M&M'S, 
white chocolate chips, 
and raisins.

Tip: To help the kids count their cereal necklace pieces correctly, give each student a hundreds chart to place each piece of cereal on. Once all 100 squares have been filled in, students can begin stringing their necklace. The same concept can be applied to their trail mix snack.

Here is a copy of a hundreds chart you can download.

The Family Project

Two weeks prior to the target date, I send home a family homework project. With the help of family members, students are to create a display using 100 items. I am always amazed at the creativity and effort that goes into these projects. The feedback from families is tremendous. Sometimes I think that the parents are more excited about their child’s project than their child is. These are a few examples of some of the remarkable projects I have received in the past.  

I am including a copy of my 100th day homework assignment, which is in English and Spanish.

On the 100th Day of School

When my students arrive, they will be greeted with a banner that reads "Happy 100th Day!" We will kick off our day with a hunt for 100 numbers. I have taken 100 star die cuts and programmed them with numbers 1 through 100. Before students arrive, I will hide these stars throughout the classroom. Students will be given a hundreds chart; as they find the stars, they can color in the corresponding number on their charts.

While students are busy rushing about in search of numbers, I will be setting up stations and briefing the parent volunteers. After a majority of the numbers have been spotted, we will commence with our stations.

To bring our festivities to an end, we will share our 100th day homework projects while we snack on our trail mix. To commemorate the day, I'll also have a few extra special gifts for my students: I used a button-maker machine to create buttons for each student. I also found bookmarks and stickers and some special pencils that I will give out at the end of the day.
