'Best practice is to find a 4th grader and have a mental math battle. :icon_tong
ok... slight thread hijack...
did you guys and gals ever play "around the world" math style? it is kinda like the basketball game where you circle the hoop making shots traveling "around the world" but everyone in the class sits in a circle, then one kid goes around the circle, standing behind someone. then the teacher asks a math question and the first kid to answer correctly, wins. if the kid standing wins, he/she continues around the circle until the kid sitting, wins, then they trade spots.
oh man that was a fun game...
speaking of which... for all those people that think they need a study group for the ASTB, I recommend that game.
