Here's a fun math trick video that your students might enjoy. It's a trick where the calculations will result in your phone number, excluding the area code. Students may find it interesting that you have to enter your entire phone number as part of the trick, but a series of calculations are performed with the digits.

I'm sharing
this just as a fun thing to use with students. It would be perfect for a time when students need a short "brain break". You'll probably
have at least one or two students who are interested in trying to figure
out how the trick works.
