Happy 100th (and 101st!) Day of School! - 1st Grade Blog (2024)

The Summit celebrated the 100th day of school this week! Many students even dressed up like they were 100 years old – complete with glasses, canes, wigs, and life alert buttons!

We began our day with a 100-themed morning meeting and brain break. The 100th day is the most exciting day of the year for calendar math! We got to finally add a digit to our 100s place on the board! We also closed up our 100 block of Digiblocks and marked off our final number on our countdown from 100 to 1. We discovered that, just like all numbers with a zero in the ones place, the number 100 is even because it can be split into two equal parts – 50 and 50. Finally, we swapped out our 99 cents worth of coins for a (real!) $1 bill! We even doubled up on calendar math because we were celebrating on the 101st day!

Next, we did a workout video related to the number 100. We had so much fun with that one!Click hereto watch at home!

After our workout, we worked on a writing prompt: “If I had $100…”. Students realized $100 was not as much as they thought! Many were interested in spending their $100 on pets, hamburgers or Legos! Some choose to give their money away or spend it on their family. Throughout the day, we continued our learning of the number 100 with many read alouds including Happy 100th Day! by Susan Milord, I’ll Teach My Dog 100 Words by Michael Frith, and Jake’s 100th Day of School by Lester Laminack. They got creative and made a picture out of the number 100.

We had fun thinking up a list of “Things Ms. Ursino Has Said 100 Times”! Frequent Ms. Ursino quotes include:
“Hustle please!”
“Raise your hand if you would like to add a blue block.” (from our calendar math routine!)
“Who wants to fill my water bottle?” (We have a room full of eager helpers!)
and “Have fun, be safe!”

We ended our day with a special snack! First graders know well by now that the number 100 is made up of ten groups of ten. We put this into action with our afternoon snack. Students counted out ten pieces of different snacks and sorted them on their snack mat paper. After they had create ten groups of ten, they had 100 pieces of yummy things!
