Sequencing learning task for place value

What is an appropriate sequencing? My sequence for the 5 sequential learning tasks as per following:

Step 1: Place Value Chart

I choose to introduce the place value chart first as I believe that by breaking down a two digit number into the chart will allow children to see how the number came about. I believe this helps to build on the child's prior knowledge of place value.

Step 2: Tens and Ones Notations
Using the child's prior knowledge of the place value chart, children should be able to understand that a two digit number is made up of tens and ones. Most of us introduce numbers through route counting and children can easily count numbers 1 through 10. Using the example of bundling sticks, children learn to count by bundling the sticks into tens and ones.

Step 3: Expanded Notations
In expanded notations, children should be able to visualize and understand the tens and ones. Teachers can further enforce this knowledge by breaking up the tens and ones.

Step: 4 Numerals

Once the children fully understand how a numeral is derived, they can be taught to write the numeral.

Step 5: Numbers in Words

The last step will be to teach children how to spell the numbers. This should be taught when they are able to recognize the numeral.
