Structured literacy is based on the idea that people learn complex things best by mastering each little part separately and then putting the parts together to create the whole. This is called part-to-whole instruction or Humpty-Dumptianism. Applied to reading, you would pull apart each of the eight strands of Scarborough’s reading rope, then teach all the little subparts related to each of the eight strands (one little subpart at a time) until all the eight strands and their corresponding subparts were mastered. The theory is that at some point, children would be able to put all the subparts back together again and engage in the act of reading.

It just makes good sense, yes?

There are 26 letters used to make the 44 phonemes found in the English language. These 44 phonemes are represented by over 280 letter-sound combinations. You teach children how to “decode” by first teaching them how to put together all the 280 letter-sound combinations so they can apply them to all the words they will ever encounter.
