Benefits of Montessori education

Montessori children learn concretely.when I was young I learnt math abstractly .starting from the association to the symbol and the quantity ,how the tens increases and how much is one hundred and how big is one thousand and doing the addition like 2+3 = 5 or 2 times 3 is 6 ,but here the children ,learn concretely through skip counting of the beads or through the solid objects.whatever the children learn they understand while they do.sometimes I envy at the children and think back the olden days where I am "terrified" of math.
