The 100th day of school is a day to let your imagination go wild! Celebrate the day with collections of 100 objects, counting activities, and lessons that dig into the physical meaning of large numbers and how they are represented. You can also explore the theme in art projects and in social studies and science lessons as well as making the wonderful literature connections suggested below.
Here are a few ideas to get you started:
- Ask students how many dimes, quarters, pennies, or 50 cent pieces make a dollar.
- Read the class I'll Teach My Dog 100 Words, and then have the class write its own versionI'll Teach My Cat (or bird or the animal of your choice) 100 Words.
- Make a class list of the students' favorite 100 books, or 100 books they have read.
- Have students collect 100 cans of food to deliver to a food pantry.
A good way to conclude the day is to have students figure out when the next 100th day of school will occur and mark it on the calendar.
In the lists of resources below, you'll find hundreds of other suggestions for using everyday objects and readily available books to deepen students' understanding of numbers when counting, estimating, calculating, and making sense of the world.
(ORC #13663, grades K2), an interactive, online game, features four activities designed to develop students' counting and addition skills. Students count and identify how many items or empty spaces are in the ten frame. They fill empty spaces with circles, bugs, stars, or apples and drag items to complete simple addition problems.
(ORC# 13606, grades K6) features six interactive, online activities that involve matching equivalent graphic representations to numbers, geometric shapes, multiplication facts, or fractions and percents. One or two students can play this matching game at their own pace to either practice facts or reinforce their understanding of mathematical representations.
In the Number Cents
(ORC# 1133, grades preK2) unit, students explore the relationship between pennies, nickels, dimes, and quarters. They count sets of mixed coins, write story problems that involve money, and use coins to make patterns. Readings from children's books relevant to this topic enhance each lesson.
In the first of two activities that focus on number patterns, Displaying Number Patterns
(ORC #1439, grades 24), students work with virtual hundred boards and calculators to highlight and display patterns and relationships among numbers when skip counting. In the second activity, Patterns to 100 and Beyond
, students skip-count both forward and backward starting at various numbers. Students can move beyond 100 and below zero using just the calculator.
The online learning tool Can You Say Really Big Numbers?
presents an engaging way for students who can read to practice saying and reading any large number that they type into the tool.
See Number & Operations (Grades PreK2)
from the National Library for Virtual Manipulatives for a great collection of online learning tools for building your students' ability to understand and use numbers.
You're an elementary teacher, which means, of course, that you frequently combine subjects when you teach. Here is a suggestion for integrating writing into your 100th Day celebration: Descriptive Writing and the 100th Day of School
(ORC #6403, grades K2).
The ORC Mathematics Bookshelf features information about using outstanding trade books in the classroom. One bookshelf entry, One Hundred Hungry Ants
(ORC #11140, grades 35), offers an entertaining introduction to division as 100 marching ants are arranged into two rows of 50 ants, four rows of 25, and more. The illustrations and math patterns make this book a fun one to read with K2 students.
