i know a trick that can help young students remember the multiples of #9 by using their fingers. starting from the left hand to the right the left pinky will be number 1 and the last finger wich is the right pinky will be #10 multiply a number by 9 lets say 9X2 bend finger number 2 wich will be left ring finger and you will see right pinky finger as 10 plus the rest of the fingers (8 of them) and its 18. it keeps going to number 10,bend the last finger(right pinky) 9x10 nine fingers remaining to the right each one representing to be a multiple of ten =90. ;) enjoy ,,gabriela roman.
