According to Bruner's CPA approach, children need concrete representation, then pictorial representation before they are introduced to the abstract form.

We were asked to sequence the notations of  place value after the concrete reprensentations of the value 34 through concrete representation of concrete materials and base ten blocks.

In my opinion, the 5 notations should be sequenced as follow:

1)  Place Value Chart.  This would be be to help them understand the value of 3 tens and 4 ones.

2)  Number in Tens and Ones.  The representation would help children further understand what they they have learned through the concrete represenatations and place value chart.

3)  Expanded Notation.  This notation helps children understands symbolic representation of the two numerals.

4)  Numerals. After being introduced to expanded notation, children will be able to understand the meaning  and realationship of  two numerals.

5)  Number words.  Finally the most abstract of all the five notations should be introduced.
