Jacob H. from Austin, Texas wrote a few computer programs to perform the numerical recycling procedure from Challenge 13.
In his response video, Jacob demonstrates how his programs work and describes his results. He also poses a fantastic new question about the numerical recycling procedure that emerged as he studied the original challenge.
What other thoughts do you have about Challenge 13? Do Jacob's results give you any ideas? How would you approach the new question Jacob poses? Get in touch and share your thoughts!
We're making the most out of Challenge 10 with a third pandigital puzzler! Check out Part 3, now available here and on our YouTube channel. While you're at it, which not have a go at Part 1 or Part 2 (or both)?
After the tests? Why not CollaboMath? Teachers: it's time for the big end-of-year tests, we know, but keep CollaboMath in mind for those last few weeks of the school year!
Consider engaging groups of students in one of these:
We continue our posing of pandigital problems this week with Challenge 10, Part 2. It's available on the front page, and also on our YouTube channel (alongside Challenge 10, Part 1).
We know that it's hard to bring in extension activities as standardized test season rolls around, but as the year comes to a close, please keep Collaborative Mathematics in mind!
Why not spend some of those last weeks after the tests making a mathematical mess with Challenge 08 -- I mean, you're probably going to recycle a bunch of those old handouts anyhow, right?
Or, maybe your students are looking for something more relaxed at the end of the year -- why not go back to counting on your fingers with Challenge 03?
We're celebrating out tenth challenge with a series of pandigital puzzlers! Challenge 10, Part 1 is now available here, and on our YouTube channel.
Speaking of YouTube, CollaboMath has recently been accepted into YouTube EDU, a free source of educational content from around the world. Thanks to all who nominated us!
We're taking a break this month, but there are still problems to be solved! Check out our recent challenges:
Make a mathematical mess in Challenge 08: The Confetti Problem. Or, be the first to take a stab at a number that's nearly 6000 digits long in Challenge 09: The Awe of Large Numbers.
We'll be back again in April with Challenge 10, so stay tuned!
