## Holy cow, Day 100 is right around the corner!

There are loads of ideas on Pinterest and teaching blogs all over the internet. The hard part is choosing the best stuff without having to spend a month on Day 100!

In the Common Core State Standards, most of second grade focuses on Numbers and Operations in Base Ten. Day 100 is a great day to celebrate the concepts of Place Value and Base Ten. Luckily, most of these activities go right along with these standards for this level!

Last year I posted about my tradition: Day 100 Caroling!  We really do go from classroom to classroom and sing a song. I wish I could share all the songs I've collected, but they're not mine to share, but I'd be glad to share my own: 100 Days Smarter. I think it's a nice reminder of all the work we've done so far this year! Plus, music, movement, and fun are all ways to help the brain remember things! Day 100 Caroling is one thing that kids tell me they remember about being in my second-grade classroom.

Here's an activity we've already been playing for a couple of weeks, since it's directly related to what we're working on in Math. (Adding and subtracting with 2 digits.) They really need to master the idea of adding and subtracting tens, and this freebie game is doing the trick!  Beanie Toss to 100

For some of my kids, I need to challenge them with more complex computations. This game is a popular one, and makes them think. With my second graders, I have them figure out the number they're waiting for ahead of time, but older kids probably wouldn't need to do that. I Have... Who Has...? gives the children practice figuring out compliments of 100.  (57 +  = 100)

Color Coded Number Grid There are tons of games that can be played on the Number Grid! My favorite is simply Race to 100 with dice or Race from 100 with dice. The children roll two dice, and proceed along the number line from 0 to 100. The subtraction version has them starting at 100 and counting backward to 0. The conversation that goes along with these games are as valuable as the number grid itself. For more of a challenge, or a quicker game, use 3 or 4 dice!

Again, with second graders, I want to celebrate 100 with more than just counting to 100. This game gives the children practice adding and subtracting 100 to 4-digit numbers.

Want to make your life easier? Grab this bundle! It's got a little bit of everything, for lots of math levels and interests!
And, of course, a few books for the occasion! Explore each image for an affiliate link to Amazon to learn more about the book! I never miss an opportunity to include literature in my math lessons.  My students love books!
