100th Day of School

With all of the recent school closings due to weather, I wasn't sure if we were ever going to make it to the 100th Day of School! But, we did and we had a great time exploring the number 100. The students began their day by decorating crowns to show they were the "Kings and Queens of 100."  Then in math the students took turns being leaders to sort through number cards to 100. They would hold up the card for their classmates and ask if the number was even or odd. They would then color-code the number with a sticker to show if it was even or odd. Every time the students completed a set of ten numbers, they would ask a volunteer to create a row of those numbers from least to greatest. As they continued to add rows, they began to see a pattern of skip counting emerge. Once completed, they realized that they had made a 100 chart similar to the one we use in calendar everyday. After completing this activity, the students made predictions about how far they thought 100 tiles would be from our classroom door. Using the same cards from our previous lesson, the students taped the cards down, one per tile, in the hallway to reinforce the skip counting pattern and to test their predictions. The students were surprised to see that 100 tiles reached all the way to the nurse's office. After taping down the number cards, the students then went back and added another color sticker to show skip counting by fives.
