My view on the sequence of place value

In my personal point of view, I would introduce the following when teaching place value.

a) number in numeral
    First of all, I would introduced number in numeral to the children. (1, 2, 3, ... 12, 13, 14,... 21 etc)
    Teacher could use concrete materials to show children the number that he or she is teaching, for example to show 10 pencils when teaching children the numeral 10 and so on.
b) place value chart representation
    With the aid of the place value chart, show children the tens and ones column. highlighting to the children
    that a bundle of sticks in the picture represents 10 and the loose sticks represent ones.
c) number in tens and ones
    Having shown the children the place value chart, introduced numbers in tens and ones to the children. Help
    children understand that in the number 48, there are 4 tens and 8 ones.
d) expended notation
    Following which, teacher could introduced expended notation to the children. eg, 98, 100, 110 etc.
e) number in words
    Finally, teacher could introduced the abstract part, which I felt that it is number in word. 100 is One
    hundred etc.
