Below are some ideas from other web sources for the 100th day of school. If you wish to narrow this list of resources for a specific topic and grade level, try entering your topic and 100th day as search terms in the TeachersFirst keyword search, setting the grade level you seek, as well.
Grades4 to 12
In the ClassroomUse the Number Tree as an excellent math conversation starter or journal prompt. Have students analyze numbers on each branch to identify the property that groups them together. Use the tree to discuss factors or multiples. Discuss questions on the site such as why the tree is bushier on the left side than on the right. Challenge students to grow the tree beyond 99 to higher numbers. Help your very concrete learners by having them "build" a similar number tree on your classroom wall using sticky notes. Color code the prime number notes as a special color so students "see" them. Try this activity on the 100th day of school to envision 100 a whole new way-- even in upper grades! Challenge your more capable students to create number trees with numbers from 500 to 599 or even higher.

In the ClassroomThis tool is great when discussing numbers that are difficult for students to assimilate, such as exponents or population growth. In elementary grades, use it for 100th day celebrations! Help students develop number sense about large figures in economics, social studies, or science. Share this site with students on your interactive whiteboard (or projector) and type in the number such as the population of a country. It will then generate comparisons that are more student friendly. Keep this reference handy as a link on your class web page to help students comprehend numbers they encounter in informational texts or even in math class.
Grades6 to 12
In the ClassroomThis site would be perfect to use when collaborating with other classrooms, for holding an author visit, or for professional collaboration. After hosting an event, share the link with students (or parents) who could not attend or who want to watch it over again. Encourage students to host their own event with topics such as book talks, interactive discussions on solving difficult math problems, or discussions of current events. Create a Vokle for parents to view, sharing your educational philosophy, classroom procedures and expectations, and other school-related information. Create a Vokle for students who were absent from class or who may want to watch the lesson again. Even elementary classes can make a Vokle under teacher supervision for special events such as Earth Day or the 100th day of school.

In the ClassroomImmerse your students into your studies with a close up in depth look through virtual field trips. Visit places where time, money, and mileage inhibit your dreams for bringing your students into wondrous worlds. Find ways to visit where your class has never gone before. Create a personalized field trip to meet your every need with the detailed tutorials given. Find ways to motivate your most reluctant learners. ESL/ELL learners will appreciate the visit. Reach all types of learners through a class visit. Use field trips as a whole class anticipatory guide, a center activity, a home connection, or even as extra credit. Challenge your gifted students to be guides to their own learning. Make your class go global!
GradesK to 4
In the ClassroomThis site would be perfect for the 100th day of school activities! Use in a computer center and have students group the snowballs into different size groups and count how many are in each pile. Have students create a scene using the 100 snowballs then write a poem about their creation.
GradesK to 5
In the ClassroomHave students add up sums of counters placed onto the 100 chart. Use this site to teach younger students HOW to count to 100 and the value/idea of 100. Demonstrate multiples of factors when teaching multiplication facts. Use on the interactive whiteboard or projector when teaching number sense to highlight odd and even numbers. Highlight prime numbers when learning prime and composite. Make this an interactive whiteboard center for students to practice or challenge each other with multiples questions. Visual and tactile learners can get "in touch" with numbers!
GradesK to 5
In the ClassroomShare the interactives on your projector or interactive whiteboard. Try some of the suggested activities and video the projects. Share the vidoes using a site such as Teachers.TV reviewed here.
There are so many great ideas for 100th day on this site! I'm looking forward to teaching the "Bundle Song" to my students!Lauren, TN, Grades: 0 - 1
GradesK to 12
In the ClassroomAlthough this site has a TON to explore, one of the best places on this site is the daily writing prompt section (find seasonal prompts at the Seasonal Items link). You can share them on your interactive whiteboard or projector with a picture and fact about the day and a question requiring a written answer. This is a great discussion starter or activating strategy with any grade level and it can already be posted when the kids enter the room or used as a prompt for blogging. Whatever subject area you teach, if you are looking for some new strategies to reach your students, check out this site.
