Math = Love: 2017 Challenge Bulletin Board

2017 Challenge Bulletin Board

I am super excited for 2017 because it means it's time for the "2017 Challenge."  Last January, I blogged about using the "2016 Challenge" with my students.

I learned about this challenge from twitter, of course.

It turned out that Jeremy Denton learned of the challenge from Mr. Collins.

After designing a template that would print on 11x17 cardstock (affiliate link) -- my go-to paper for making awesome classroom posters and displays!

I put up this bulletin board last year:

I've edited the files for 2017 instead of 2016.  I also changed the font to my current obsession, Wellfleet!

For each integer between 1 and 100, inclusive, there is a space for students to write the solution.  There is also a space to the right for students to write their name to show who found the solution.

ALL solutions must be verified by me before being added to the posters!

The last page in the file includes the instructions.  Students are asked to create each integer between 1 and 100 using only the digits in 2017.  Repeating digits is not allowed.  Students may use any mathematical symbol or operation.  Files are uploaded here.

One thing I love about this challenge is it encourages students to learn about factorials which they haven't had much exposure to at all.

Last year, it was fun to watch students work through this challenge.  We did not complete it last year, but it is not always possible to find solutions to each number.  The number of solutions that are possible depends on the year!

I look forward to challenging this year's students.  I'll update this post when I've got the new posters hung up in my room.  But, I thought I would go ahead and post this to give y'all a head start to get ready for 2017!

Looking for another challenge?  I highly recommend that you also check out the 5-4-3-2-1 challenge!


  1. Sarah-

    I've been following your blog for some time now, though I intend to become an English teacher. It was your suggestion that led me to read Designing Groupwork. My question, given the message of that book about status, is this: Does the slot for students to write their names and take credit for a solution invite students to perceive academic status differences among classmates?

  2. Is there any acknowledgment of additional ways to create a number that's already listed?

  3. Was wondering the same thing as Connie. I'm doing this schoolwide and I'd like everyone who has a solution be acknowledged. Just can't figure out how to do it on the paper. There will clearly be some numbers with very few (or no) answers, and some that will have LOTS. Any ideas?

  4. Did this last year and had a great response so I made sure to have the 2017 challenge read to go. We started school yesterday and my students already have the first page filled in. I have students and one teacher, from last year come looking for it.

  5. Thanks for the reply, Sharon, but I'm still having trouble figuring out how to lay it out so multiple answers (and the authors) can be displayed

    1. Sorry that got left off. I enter only the name of the first person to submit a correct answer but acknowledge other correct answers verbally in class, especially if they are interesting. Answers are submitted by pieces of paper on my desk, face down. At the end of the day, I flip the pile over and the first one is on top.

  6. A little late, but I just set this up for my students. I can't wait to see what they come up with! Thanks for sharing!
