Hooray! It’s the 100th day of school!
It’s a great day to celebrate all about math and to plan some fun activities for the 100th day, all focused around the number one hundred! 100 feels like a big number when you figure that you’ve been in school that many days, but it’s not quite as big of a number when you only have 100 seconds to complete tasks!
I have used these activities with students from first grade to 5th and I have the activity booklet to offer you for free!
There are a bunch of ideas and response pages for students in the 100 Second Challenge freebie linked here, but I’ll list a few for you here!
100 Board Match-
Pull as many numbered tiles as you can out of a bag and match them to the hundreds chart! This is great for helping students to read numbers, navigate the 100s board, and also determine how well they understand how the board works.
How many pennies can you stack in 100 seconds. For older students you could just do a coin challenge and have them calculate the value of all the coins they stacked within 100 seconds!
Toss as many marshmallows as you can across the table in 100 seconds. This one is just fun and gets lots of laughs!
How many beads can you put on a pipe cleaner in just 100 seconds?
There are 10 challenges in all included in the booklet along with direction cards for each of the activities, so be sure to grab that freebie here!
I also want to share a couple of other fun ideas that I’ve done for the 100th day before that your students might love!
100th Day Snack
This snack includes 100 pieces of snack! I always like to have 10 choices for snacks and students take 10 of each (to work on that place value skill as well). Some ideas for choices are different kinds of cereal, Goldfish Crackers, Cheezits, pretzels, m&ms, oyster crackers, and fruit snacks.
100th Day Crown
I’ve just used basic sentence strips. Students put 10 groups of 10 different stickers, shapes, squiggles, and they make 10 of each (another plug at that place value concept)
100th Day Cereal Necklace
This is always a fun one. You can use any cereal that’s in the shape of a circle, but I like using Cheerios honestly. I have students bead 10 cheerios, then a plastic bead to break up the groups of 10. Of course they do this 10 times! It’s also been best in my experience to splurge and get the string that has the ends like a shoelace so they are easier for students to bead.
