AS IN THE LONG AGO

This is the title of a maths game devised by Zoltan P Dienes .  He thought up a lot of games.  This one is a way of gradually familiarising children with the ideas underlying place value.  To play, you need Duplo or Lego, though you could use any construction toy, and you need a dice marked with only the numbers 1, 2, and 0.  The players throw the dice in turn and collect bricks according to the number they throw.  When they have enough to stick 3 bricks together they must do so and shout SESAME!  If they don't, another player can say SESAME, claim their three bricks and make their own SESAME with them.
