I'm challenging myself to name 100 ways to celebrate 100 days. So, here goes . . .

- Estimate how far 100 feet is, student feet, that is. Using sticky notes with their names on them, have your kiddos place their notes where they think 100 feet from the classroom door will be.
- Have your students trace the outline of their shoes on construction paper and cut them out. Then line them up, heel to toe in the hallway to determine the correct answer. Give a certificate to the student(s) who came the closest to the correct distance.
- If your students are capable, have them figure out how many construction paper feet each one needs to make using operations. If they are not able to do that much math, have them count off by 2s, making tally marks or holding up fingers to track how many times they gave the next number in the skip counting, thus determining how many sets of footprints to make.
- Give each student a 1 quart ziplock bag to take home. Direct them to find 100 of the same item to put in the bag and bring them to school on the 100th day. Stress that all items must fit in the bag and that are dear or valuable are to be considered carefully as their collections will be manipulated during the day. Thus, there is the risk that breakables could be broken and valuables lost. My personal preference is that they not bring in food that will attract bugs or vermin.

__100 Hungry Ants__, by Elinor J. Pinczes. - Save the ads from your Sunday newspapers and bring them to class. Challenge your students to find ONE item they could buy if they had $100 without going over $100. Ask them to record their purchase on a $100 bill representation.
- Then ask your class to find 2 items they could buy without exceeding their $100. Again they should record their purchases.
- Repeat the task with as many numbers as you deem appropriate. I recommend 4, 5, and 10, at the least.
- Bring in 3 jars (mayonnaise jars work well) that you have filled with a collection of objects. Make 1 jar = exactly 100. Make the other jars greater than and less than 100. Ask your students to vote for the jar they think has exactly 100 objects. Near the end of the day, count the objects in each jar to determine who selected the correct jar. Give certificates to those who guessed correctly.
- Have your students determine the year in which they will turn 100 years old.
- Discuss signs of old age. Have your students draw a picture of themselves as they will look at 100. For extra effect, have them crinkle the paper after their drawing is complete to make their faces look wrinkled.

__Miss Bindergarten Celebrates the 100th Day of Kindergarten__, by Joseph Slate. - Ask your students to write a paragraph about what they think they will be doing when they are 100 years old.
- Prior to 100th day, begin compiling a list with your students of 100 words they can read and write. On the 100th day, have a spelling bee using those words. For older students, challenge them to name 100 words that pertain to a specific subject (science, math, social studies, food, nouns, verbs, ...). Use those words for the spelling bee.
- Promote team work by providing several 100 piece jigsaw puzzles. Divide the class into equal small groups; then give each group a puzzle to complete. Certificates to those who finish first!
- Thumbs up to thumbprints! Using a stamp pad, their thumb, and a marker, students will print their thumb on paper 100 times. Each time they make 10 thumbprints, they should stop printing and use the marker to circle that group of 10. Encourage them to label each set with the appropriate decade.
- Calculate what year it will be 100 years from now. Ask each student to draw and describe something that schools will have then that they do not have now. Collate their pages and illustrations into a class book.
- Give each student a 10 x 10 grid. Flip a penny 100 times, recording H (heads) or T (tails) on the grid cells.
- Calculate how many Tails appeared in #18; calculate how many Heads came up.
- On another 10 x 10 grid, have students record the numbers that come up as they roll a die 100 times.
- Have your students graph the results of #20.

__100 Days of School__, by Trudy Harris. - Have small groups of students make trains with unifix cubes. Each train should be exactly 100 cubes long. Compare the trains. Are they all the same length? If not, which one is correct? The only way to figure that out is to break the trains into equal lengths (I recommend 10). Give certificates to the students who used exactly 100.
- Brainstorm a list of activities from the 1st 100 days that are memorable. Limit your list according to the age and stage of your students. Create a class graph of their favorite activities.
- Working with a partner, complete this writing activity: If we had 100 _____, we would _____. The partners write about their idea and then illustrate it.
- Another writing activity, perhaps more appropriate for older students: Write about what it may have been like 100 years ago. What would not yet be invented? What would school have been like then?
- Read aloud
__The 100th Day of School__, by Angela Shelf Medearis. - Take a brain break and do 100 jumping jacks.
- Because the 100th day falls in Feb. in my district, I include a Black History activity. The challenge is to compile a list of 100 African Americans of note.
- Have a coloring race. Give each students a 10 x 10 grid. Using a die, each child rolls a number and then colors in that many squares. Students should change colors for each roll of the die. Play continues until 1 student reaches 100. If you like, require the children to roll the exact number they need to complete the grid. That is, rolling a 6 when you need 4 to finish will be disallowed. They must roll exactly a 4 or a combination thereof. Give the winner(s) a certificate and a pat on the back.
- Another variation of the coloring race is to give each child 2 dice which they roll together. The number of squares they get to color is the sum, difference, product or quotient of the 2 numbers. It's your choice!
- After everyone has finished coloring their grid from above, have them cut the grid into the 100 squares. Use the squares to create a mosaic picture. This could be 1 huge, full class mosaic or each students could complete their own picture.

__The Night Before the 100th Day of School__, by Natasha Wing. - Hop on your right foot 50 times. Then hop on your left foot 50 times.
- Create paper chains of exactly 100 loops. Join them together with a distinctive loop and hang them around the room. Now you can count by 100s!
- Sing the following song to the tune of
*Ta-ra-ra Boom De Ay:*It's the 100th day/ So shout, "Hip hip hooray!"/ We'll count and eat and play/ on the 100th day. See all we've collected/ 100s on display/ Join in the fun and say,/ "Hooray for the 100th day!" - Clip 100 paperclips together. With a partner, measure things in the room. Find 2 each of the following: shorter than, longer than, and equal to the 100 chain.
- Have a 100 snack -- a pretzel stick and 2 round or oval crackers. Tell you kiddos that it's a 100 snack, but they can't eat it until they figure out why it is a 100 snack. (You may wish to discourage the breaking of the pieces into 1000s of crumbs!)
- Make 100 placemats and deliver them to a nursing home. I guarantee they will be appreciated by the seniors.
- If your 100th day is near Valentine's Day, make 100 Valentine cards to send to soldiers who are deployed overseas.
- Enlist the P.E. teacher to make the children do 10 different in sets of 10 exercises. For example, 10 sit-ups, 10 toe touches, 10 push ups, etc.
- Have the students estimate how long 100 seconds is. The teacher uses a stopwatch, declaring the start time. Students stand up when they think 100 seconds have expired. The teacher may wish to note which student(s) were correct, if indeed, any were correct. Repeat this exercise at various times throughout the day. Hopefully, the children will get better at estimating the time.

- Give small groups 100 pattern blocks to share. Together they should make a design. Take pictures of their designs and display the pictures in your classroom.
