Leading up to this momentous milestone, Kindergarten House Advisors created a variety of activities and lessons to give students a fuller sense of what the number “one hundred” really means, including:

• Solving math problems using a 100-grid.
• Drawing a self-portrait showing what they think they’ll look like at 100 years old.
• Illustrating and writing sentences about 100 things they would like to have and 100 things that would not want to have.
• Figuring out different ways that 100 objects could be divided without leftovers.

Teachers also asked Kindergarteners to collect 100 small objects and place them in a box. Students gave clues to help each other guess their collections and then arranged the objects into groups.

On their 100th day of school, all Kindergarteners, those learning in-person as well as virtually, each received a commemorative pencil, pad, and eraser, decorated with a picture of a $100 bill. They also received a special pair of 100th Day glasses as you can see in the photos. 

As a fun 100th Day math activity, House Advisors gave students mini-marshmallows and toothpicks. The children had to count out 50 marshmallows and 50 toothpicks and construct their very own marshmallow monster. After taking a picture of their monster, students celebrated their accomplishments by eating their delicious materials!
