Depending on your school calendar, your one-hundredth day of school is probably coming up soon. Many teachers use it as an opportunity to teach lower elementary grades number sense, or just for the fun of it. Explore these websites for online and offline activities, all about the number "100."
Enchanted Learning has an awesome collection of project ideas for the celebration of one hundred days of school, such as Name 100 Animals, Write Your Name for 100 Seconds, Name 100 Countries or Collect 100 Cans for Charity. Some of the printable worksheets, including the cute One Hundred Days of School printable book, are only available to paid members, but there are still plenty of free resources here.
Kindergarten teacher Mrs. Flanagan has so many fun hundredth-day-of-school activities that her class celebrates for a whole week. I like her collection because she includes photos of the activities, although not much in the way of annotation. "We estimated how many paper clips we could drop in a full glass of water before the water spilled over. Can you believe the water didn't spill over, even after we put 100 clips in it?" For more one-hundredth day activity ideas, follow the links to A to Z Teacher Stuff in the header of the page.
Mrs. Meacham is an elementary school teacher in Wisconsin, who enjoys creating websites in her free time. Here she shares some of the activities that she's done in her classroom for the hundredth day of school. "100 Words: Students get a clip board and a pencil and roam the room to find and write down 100 words. No duplicate words are allowed." For most activities, Meacham includes printable worksheets, although a few of the links are broken. My favorite click is the printable six-page activity book, "My 100th Day of School Book."
"My name is Max, and this is the truth./ I'm six and a half. My best friend is Ruth. / We like to solve problems all about math, / Like adding, subtracting, patterns, and graphs." Two of Max's nineteen rhyming adventures are perfect for the hundredth day of school: Counting Coins and A Sweet Story. Counting Coins is about counting one hundred pennies by ones, twos, fives and tens. A Sweet Story is about estimating the number of lollipops and jelly beans in the candy shop.
"It's the hundredth day of school. Let's count to 100! Hurray!" This simple Flash game involves reading number words, counting with tally marks, and counting to one hundred by tens. In each frame, start the animations by clicking on the girl and the boy, as there are two different animations in each picture. For three printable activity sheets (Dot to Dot, Missing Numbers and Write About 100), click on the printer icon in the lower right of the game in the last frame.
