The problem
Teachers following a structured literacy sequence need practice material for exactly where their students are this week. What's available online is generic, it introduces sounds and patterns the class hasn't reached yet, which does more harm than nothing.
What it was costing
Teachers building their own materials at night, or spending prep periods filtering through worksheets looking for the handful that fit.
What we built
ReadUp!, structured literacy practice aligned to the UFLI scope and sequence. Pick where the class is; get material that matches it.
The result
Prep time goes back to teaching. The practice reinforces the lesson instead of contradicting it.
