       Here is a “magic trick”Give kids colored cards.red card- 1 dotblue card- 2 dotsgreen card- 4 dotsyellow card- 8 dots“Show me a total of x dots!”(x is a number between 1 and 15)“look around, why are you all holding up the same cards? isn’t anyone creative enough to find another way?”then ask what goes on the “next card”

       @futurebird Brilliant! Though I would like plan ahead for the kids who, when you ask for 6, uses the red card flipped over to hide 2 dots on the yellow.

       @futurebird More advanced, but you could do a similar trick with the unique prime factorization of numbers.I had fun using prime factorizations and the commutative property of multiplication to find anagrams here:https://remcycles.net/blog/awk_anagrams.html
