   I'm really excited about how well one of my new lesson ideas for fifth grade CS is working out.

   I teach them to count in binary early in the class which they LOVE. In the new lesson I have seven sets of cards with numbers and symbols on them from:

   binary
   hexadecimal
   base 3
   base 3 but with different symbols
   base 5 but with different symbols
   cuneiform
   decimal

   Each set of cards contains numbers from 1 to 150. Students put them in order and match symbols of the same value.

   It's chaos.

     I trust you used the old joke about why CS folks exchange gifts on Halloween 🎃 🎁.

     Because Oct 31 = Dec 25 😄

     I have a worksheet where you add, subtract, multiply and divide words in HEX and fifth graders find this VERY amusing.

     Things like D6FD-CAFE=BFF

     (If you know of any good hex math problems like this please share as I collect them. )

     We then work on short conversion programs in python. If anything they come out of it with a better understanding of multiple number bases... but I think we could also learn some things about sorting with some adaptation.
