IT'S THE NUMBER THAT A STUDENT WORKS WITH UNTIL HE KNOWS IT "UPSIDE DOWN AND BACKWARDS" WITHOUT HESITATION. THAT IS WHY WE CALL IT A "JUST RIGHT NUMBER."
AFTER BEING COMPLETEY FAMILIAR WITH THAT NUMBER THE STUDENT THEN REPEATS THE PROCESS WITH THE NEXT NUMBER UP, AND SO FORTH.
THESE GAMES ARE FUN ACTIVITIES PROVEN TO INCREASE YOUR STUDENT'S SENSE OF NUMBERS AND MATHEMATICAL UNDERSTANDING.
HAVE FUN !
