Our Curriculum
LettersPractice teaches two kinds of thing.
First, the big ideas or categories of phonetic rules — like letters make sounds or two letters can team up to make a sound. These arrive in micro lessons that a grown-up reads aloud.
Second, each big idea holds a collection of facts — like or . These arrive one at a time, in everyday practice.
But not all facts are created equal. , from Lesson 2, gets more use than Lesson 1's , , and put together. So we allow for multiple active lessons to feed content at once — data driven — the most useful facts first.
At any given time, a learner is getting familiar with one or two new facts and a maximum of one new idea, always focused on growth toward real world reading independence.

Facts for this idea:
As facts are released into rotation, they fall into the hands of our learning engine, which selects exercises optimized for uptake, retention, and recombining the old with the new. When facts are shaky, new facts are stopped until we have good evidence of recovery and solidification.
