8. 100 Foot Prints:
With a friend- trace each others’ feet.

  • Each child colors and decorates one foot; do this with each child in the classroom/program. Do both feet if necessary.
  • Combine all decorated traced feet and tape the footprints down the hall.
  • Mark off every 10 feet until you reach 100 feet.  (Talk to Principal of School to see if there is an area where you can do this…)

9. How many times can students write their name in 100 seconds?  Predict, and then actually do it.

10. Snack – Use one pretzel and two oval crackers to make the numeral “100”. Using an oval template a little smaller than the cracker, cut two pieces of cheese to go on the crackers.

11. Play music…Dance for 100 seconds…stop… then do again…

12. Predict how far 100 steps will take you? How many to the gym? To the playground?

13. This one combines…Puzzle Fun, Prizes and Community Service all in one!

  • Break the children into groups and put together 100 piece puzzles.
  • Consider using some of them as prizes– or take a few to an Assisted Living Home when the puzzles are completed.

14. Good Idea for a ‘Graffiti Wall’!

  • On the 100th day of school put together a list of 100 things in which staff and youth are thankful.
  • Put these on a large sheet of roll paper. (Put a titile above it that says, “The Graffiti Wall”)
  • Encourage kids to be creative and thoughtful as they come up with their ideas.
  • The word “things” does not necessarily mean material items.
  • Leave up the wall for the week.
  • This can be started BEFORE the 100th Day.

15. One Hundred Hanging Objects:

  • As a group, decide on a “set item” such as hearts for Valentine Day– or some other object that correlates with your current theme.
  • Each child would make items to get to the “100” number to hang in the room.
  • Some thing could also be illustrated or written on the objects that relates to the theme. (For hearts, children could draw or write kind actions they can do for others.)
  • Attach the 100 objects to various lengths of yarn and hang in the room.

16. Try to get painter’s caps donated from a local lumber yard. Decorate the hat with 100 things. You can use 100 dots, stripes, ribbons, macaroni, popcorn kernels, cereal, buttons, or stickers!

An heart cutout with lots of different color hand cutouts filling the inner section of the heart.

17. Make a poster for your hallway that has 100 painted handprints. This heart shape would be nice.

18. In one program, children popped 100 balloons in the gym while they were timed to see how long it would take. (A middle school program was enlisted to help blow up the 100 balloons–A nice Community Service) The kindergarteners loved it. It really got the children” pumped” for the special day!

19. For kindergartners learning to write to 100…

  • Have children work with a partner (pair up a child that is struggling with someone who is good with numbers).
  • They write to 100.
  • Each child has a different colored marker, and they alternate writing the numbers. (For example 1 is red, 2 is blue, 3 is red, 4 is blue…..on and on to 100).
  • The kids will love to do this; it’s amazing how much they teach each other!!

20. Do you have an After-School Program? Hold a school wide contest entitled “Guess which jar has 100 pieces of candy”. Each student in the school is given a ballot prior to coming into the program or area.

• They  first view your children’s 100th day projects and then guess which jar has the 100 pieces in it.

• Students drop their ballot off in a basket next to the particular jar they believe has the 100 pieces of candy. (There are jars of small wrapped candies.)

• To add on to this idea— the visiting children go out into the hallway and walk the 100 footsteps that are laminated on a roll of paper and taped down to the hallway floor.

• Near the end of the day, the winning jar # of candy is announced, and one piece of candy is distributed to each winner…Or if there is one winner, they can share the candy with their class!  Their name and room # are on the ballots.

21. Set up 100 cereal boxes in domino fashion and have children knock them down to watch them fall.   (Start collecting the boxes well in advance!!!)

22. Take an indoor parachute and popcorn 100 pair of rolled up socks… (Start getting old sock donations early!) Or put 100 one dollar play money bills in the parachute.

23. Read the book 100 Hungry Ants.

24. Before the 100th day – have children make posters with each child stamping 10 times on a piece of paper. Do this until you get to 100 stampings on each poster. Write “Happy 100th Day!” and post them around your area.

25. Have contests:

  • Who can count backwards from 100 the fastest?
  • Who can jump 100 jumping jacks the fastest?
  • Who can jump-rope to 100?

26. A “Penny Harvest”: Each child is asked to bring 100 pennies that they harvest up from the loose change at home.

  • The students estimate how much 100 pennies would weigh.
  • How high they can stack 100 pennies.
  • How many pennies it would take to outline a child.
  • What the grand total amount would be of the pennies.
  • Find your birth year on a penny.
  • When done… donate ALL the pennies the students in the program collected to a local charity.

27. In the USA, the hundredth day usually falls in February— for ‘Black History Month’ put together a bulletin board with the children compiling a list of 100 African-Americans that have made a difference.

28. As each child enters the door on the 100th day, give them a number.

1. All through the morning and afternoon , set a timer to go off every 10 minutes.

2. At that point  someone takes a number from a hat – and the child with that number gets a small prize.

3. Every 100th minute, the winner gets two small prizes. Children enjoy the anticipation.

4. Count by tens every time the timer goes off and kept a record on chart paper or whiteboard/blackboard.

5. When outside make sure you have the timer and prize box.

6. Stop after every child has a prize!!! Have children take a prize if they leave for home before their number is chosen.

29. Celebrate the 100th day or week celebration by shaking milkshakes –100 times. Make shakes from softened ice cream, milk and chocolate syrup if desired… put all into a tight containers. Have children count to 100 as they are shaken. Pour into individual glasses and add straws…Kids will love them!!!

30. Give each child in your program— slips of paper that will eventually form a paper chain… The amount of slips of paper each child receives will be based on the number of kids in your program. (If you have many children consider doing 200 or 300)  Have each child write different things they enjoyed most in your program or class to this point. (One experience to one paper loop) Connect the 100 fun things together and hang it as a paper chain.

31. During “100th Day” week put up a large sheet of butcher paper; you can also use a black board/white board with the title  “100 HAPPY Words”. Words make the world go around and words that are “Happy” do affect the environment of your program!

32. TWO COMMUNITY SERVICE IDEAS: Collect 100 items for your local Humane Society. The children can donate food, treats, and toys for the animals. Count, sort, and graph the items. ‘Kindness Week’ is also in February–so this works well with that! Collect 100 returnable bottles and donate to a charity…

33. Tie the hundredth day with ‘Acts of Kindness’.

  • Make a tree out of poster board & add leaves using green, yellow, & orange construction paper.
  • On each leaf write good deeds done by the children.
  • Keep adding to the tree until it is blooming with 100 acts of kindness.
  • The book The Giving Tree by Shel Silverstein would work with this activity.

34. This idea is great for Pre-k and/or a Kindergarten  program.

  • Read the Wolf’s Chicken Stew…and then take the children AWAY from your room.
  • Have someone hide 100 paper chickens cutouts around the room.
  • Have chickens sticking out of books, in the play bins, in children’s boots, under the tables and up/down/in/out of everything…!
  • When children return have them find the chickens and group the chickens in lines or piles of 10’s.
  • Keep searching until children just don’t find any more! It’ll be a nice surprise when a few chickens are found over the next week or so.

An image of jewelry. Lots of necklaces, bracelets, and earrings.

On the 100th day of school, I put on tons and tons of jewelry. The children guess whether I have less or more than 100 pieces of jewelry on. I cover myself in bracelets, pins, beads, chains, rings, etc. We chart all the guesses and all children get a treat…but the child who comes closest to the exact number gets an extra treat. (Usually it is OVER 100)

ALSO—my two assistants dress as if they’re each 100 years old. They hated the idea at first–but now really have a ball with it. Strangely, the kids are a lot more gentle around them on that day!!! LOL

76. THE 100 INCH DASH! (Game)
You need: yard stick and tape

  • Measure out 100″ on the floor or field.
  • Mark a start and finish line with the tape.
  • Start the race at the signal and try to reach the finish line.
  • What makes this difficult is that the children are to move their feet only one inch at a time by taking baby steps!
  • The winner crosses the finish line first.

77. & 78. MORE ‘DASH GAME IDEAS’… These two ideas come from Kelsey Paschetto at Howevalley Elementay School..(Thank you Kelsey for sharing!)

• Kelsay shares that she modified the 100 in dash (#76.) and turned it into a relay race. Her older elementary students had a blast with! (I love that idea! Barb)

• She also does a 100 in BALL TOSS.
Using the same  tape from  the “Dash Game in #76 and #77), the first person in each team starts at the same time.
After they have taken ten steps and crossed the finish line, they turn around and toss a soft ball.
If it is caught, they get to sit down. If not, they go to the back of the line for a second try.
Each team member continues in the same manner. The first team to have everyone sit down wins. If numbers of players are not even, Kelsey catches the last ball…

Make a large poster in the shape of the number 100 to hang in your classroom/program area. SEVERAL WEEKS before the 100th day of school, discuss acts of kindness toward others. Based on the number of youth in your group, two to three weeks before the big day, announce open season on acts of kindness. Encourage the children to recognize acts of kindness by others.

Each time kids see a classmate or friend engage in an act of kindness, they will tell staff and then put a sticker and their friend’s name on the poster. The students can NOT name themselves, only others.

It should be easy to reach the goal of 100 acts of kindness. A profound difference in behavior, relationships, and outlook will be noticed.

Collect 100 hugs. Keep track on them on a chart.

81, 82, & 83…The following three ideas come from  Sue Morgan! Thank you Sue

•We use an Atlas and make a list of 100 cities in the United States

•We make a list of 100 pairs of Homonyms or Antonyms

•We each get a large piece of art paper & draw 100 of the same item on it.
Everyone must do something different.
I tell them to think of something simple & something they would like to draw. It usually takes two days. They learn quickly that 100 is a lot of things. The posters turn out cute & we display them in the classroom.


84. MAKE SHAKER PUDDING – Pour 2 cups of milk into a jar/container with a lid, add 1 small box of instant pudding mix, and shake 100 times. Have children take turns shaking and counting together as a group!
