Two to Start Off the Week


1)  First another enthusiastic testament to the "flipped" math classroom, by someone who tried it for the first time, and has glowing things to report:

Right from the start he writes: "... let me just say that I am never going back to the Stand and Deliver model that so many teachers are reluctant to alter in any way."


2)  Haven't had a puzzle for awhile, so here's a simple-looking one from Ben Vitale that might keep you busy for a wee bit. A 3-digit number and a 2-digit number are multiplied... what are all the numbers involved?:

ALL E's represent even integers, and ALL O's are odd integers (but not the same integer):

             O E E
           x    E E
       ___________
           E O E E
    +     E O E
    _____________
           O O E E
