## Reflection: Diverse Entry Points Variables - Section 2: Variable Puzzle

I was surprised that one of my students began at the bottom of this puzzle by thinking that the only multiplication problem with a product of 5 is 1x5.  He then worked his way up the symbols, rather than beginning with the division problem at the top.  This was a wonderful discussion about how you would have to test the values for the variables in different locations.
