100th Day Gumball Craft

Of all the 100th day math activities, this gumball machine craft might be my favorite… and, I think that holds true for the kiddos as well!

All you need for this craft are bingo dotters. The students will count to 100 either by 1s, 5s, or 10s, as they dab each circle.

100th Day Crown

A party isn’t a party without a party hat, or in this case, a party crown! For this 100 Days Smarter Crown, I like to prep strips of construction paper that measure 3″ x 18.”

The students color the school house and each school bus. Then, they sequence the numbers by 10s as they glue the buses onto their strip of construction paper.

Last, I measure around their heads and staple. They get to wear their special 100th Day crown all day long!

Build the Number 100

For this math station, I like to make bins of everyday classroom manipulatives, including pattern blocks, building bricks, popsicle sticks, snap cubes, and more. Then, the students will build the number 100, using each manipulative.

For a guided building activity, print this pattern block work mat and have students build the number 100 with pattern blocks.

Then, they can record how many of each shape they used, including how many shapes in all.

100 in a Line

Another great activity for counting to 100 is this “100 in a Line” game. Gather teddy bear counters, linking cubes, chain links, etc. Then, have the students create a line of that item all the way to 100.

Once you have 100 in a line, the students can easily compare the length of lines to see which group of 100 is longer or shorter.

100 Stickers

Stickers are always a hit among kindergarten and first graders, so as you might guess, this 100 sticker mat is one of their favorite 100th Day math activities!

To help strengthen fine motor skills, we stick 10 groups of 10 stickers onto each space of our sticker mat.

100 Punches

For additional fine motor practice, we punch 10 punches on each page of our “100 Punches for the 100th Day” punch book.

At the end of this activity, the students will have a booklet with 100 punches.

A handheld hole punch works great for this station; but for added fun, I like to have a variety of shape punchers available as well.

100 Punch Out

I often combine this “100 Punch Out” printable with the 100 punches booklets. When the students finish punching all 100 punches, they will practice tracing and writing the number 100.

Then, they will punch out all of the number 100s along the outside edge of the paper.

How Much Does 100 Weigh

At this 100th Day weighing station, the students will weigh their collection of 100 items using a balance scale and teddy bears, pattern blocks, and linking cubes.

You could also have them compare the weights of 100 of each item to see which set of 100 is heavier or lighter.

100th Day Necklace

This is one of those 100th day math activities that is an absolute must! First, the students count 100 Fruit Loops by placing each piece of cereal on their ten frames counting mat.

This is by far the easiest way I’ve found for the kiddos to keep track of all 100 Fruit Loops!

Next, they strengthen fine motor skills by stringing them onto a piece of curling ribbon. For five tips on making your 100th day necklaces without the stress, head to this post!

Whole Group 100th Day Math Activities

100 Exercises

Another fun way to count by 10s is by exercising to 100! For this activity the students will complete 10 reps of 10 different exercises.

You could also set a timer for 100 seconds. Then, have the students count how many reps of each exercise they can complete in that amount of time. These exercises make great brain breaks throughout the 100th Day!

Number Hunt

For this activity, hide numbers 1-100 around the room. You can use number cards, magnetic letters, foam numbers, numbered stickers, and more. Then, have students go on a number hunt, collecting numbers in a bin or basket.

Once all of the numbers are found, we order the numbers in a pocket chart or on a hundreds chart.

Hundreds Chart Puzzle

This is another great activity for sequencing numbers. Simply cut up a printable hundreds chart into random pieces. The students will reassemble the pieces to build the hundreds chart.

Missing Numbers

Here is one of the easiest, low prep 100th Day math activities! For this activity, remove numbers from a hundreds pocket chart. Then, have students determine the missing number using the numbers before or after the missing number.

This is the perfect activity to include during your number talks, as students explain how they determined the missing number!

Count Around the Circle

This game can be played as a small group or whole group. Have students sit in a circle. Then, the students count around the circle, as they say the next number until you get to the number 100.

For an added challenge, you can set a timer and try to beat the preceding time. You can also count to 100 by 2s, 5s or 10s.

Early Finisher Activities for the 100th Day

Lace the Number 100

To practice fine motor control, we thread and lace these number 100 lacing cards. This is a quick and easy early finisher activity for the 100th Day.

Printing on card stock and laminating for repeated use is best.

Dab the Number 100

The students can dab the number 100 using a cotton swab dipped in paint, as an early finisher activity or math center.

Dabbing the paint into each circle requires precise fine motor movements.

Number 100 Maze

For this early finisher activity, the students will locate and mark the number 100 to finish the maze.

I like to place a stack of these number 100 mazes in a tub for my fast finishers to easily grab and take back to their seats.

Spot the Number 100

“Spot the Number 100” is another quick early finisher activity that can be placed inside a basket for the students.

To complete the activity, the students will use bingo daubers to dot the number 100.

Number 100 Spin and Trace

This “Number 100 Spin and Trace” activity is an engaging way to practice number formation.

The students will spin the spinner and use a crayon, pencil, and marker to trace each number 100.

Roll and Race to 100

For this early finisher activity, you will need a printable hundreds chart, a foam die, and 1-2 counters. If a student is playing alone, they will roll the die and move their counter until they reach the number 100.

For added fun, the students can race a friend to the number 100. The students will take turns rolling the die and moving their counter that many spaces. The first to 100 wins!
