how many ways can you make 100? and other hundredth day fun

100th day of school

Here is an easy math idea for the 100th day of school, or any day really. I actually started this on the first day one year and used it as a math warm-up with 3rd graders. Each day, we would find as many ways as possible to make that number. I think that was the only year I actually kept up with a school day count, but it really was a simple and quick activity that makes them think and requires no preparation.

I just had students do this in their math journal. Give students 3-5 minutes to come up with as many as possible. At first, students would write down one or two, and say, “I’m done.” To which I would reply, “No you’re not.” Clever huh? But that was the only rule, as long as there is time to think, you keep thinking. (The 3-5 minutes helped me gather the stuff and materials we needed for the math lesson.) Then I would call on volunteers to put examples on the board/chart/Smartboard. I would always stress finding the most unique and different possibilities that no one else came up with. They loved the challenge. It’s very open-ended.

Since the 100th day is coming up, why not see how many ways you can make 100?

And if you’re looking for more simple, little-to-no prep activities that make students use their brains for the 100th day.  Here are some ideas. 100 ideas to be exact, and they are all geared toward upper elementary. (This is the kind of thing I do while my husband watches wrestling.)
