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!

Challenge 08 has received its first video responses, courtesy of Andrew. Check them out on the Challenge 08 archive page and prepare to be astonished by the size of some of the numbers he encounters!

Speaking of the Awe of Large Numbers, Challenge 09 Part 1 is now available. Have a look and share your thoughts in a response video!

And while I have your attention, please take a moment to nominate the Collaborative Mathematics YouTube channel for inclusion in YouTube EDU. You'll need two links to do so:

1. The nomination form, available at: https://www.youtube.com/yt/edu-whitelist/
2. The CollaboMath YouTube channel, online at: https://www.youtube.com/user/CollaboMath

Thanks for your support!

We're keeping up with our experiment in a new rhythm: a video every two weeks!

Now available: the second half of Challenge 08, which continues the paper ripping-theme, and provides teachers and students with yet another pedagogically sound reason to make a mess.

Challenge 08, Part 1 explored a simple procedure for ripping up a piece of paper. Challenge 08, Part 2 presents a new procedure, with a small twist that leads to a whole bunch of new problems to investigate!

Enjoy!

Math can be messy sometimes. Grab some scratch paper and get a rippin' with Challenge 08: The Confetti Problem (Part 1).

Also, I'm going to try out a slight adjustment to the usual format. I've typically published one video per month, and that video has contained both a main challenge and some extension or elaboration.

This spring I'm going to try separating those two aspects. There will be two videos per month, connected to the same theme. The first video will contain the main challenge, and the second will have questions that extend or augment the ideas from the first.

I'll be interested to hear your thoughts on the new pacing! Plus, I look forward to seeing some response videos about Part 1. Stay tuned for Part 2 in about two weeks!
