Supersonic Phonics Books in Order
3 books by Robin Twiddy; Angela Mayers. Reading level: Grades 3.3–3.8. Lower Grades (Ages 5–8).
Series books grow with readers — but that's also the trap. Most series start at one reading level and one content intensity and drift upward over the course of the run. Supersonic Phonics (3 books by Robin Twiddy; Angela Mayers) lands at reading level Grades 3.3–3.8, with average content intensity 1/5. Intensity stays consistent across the series — a kid who can handle the first book can generally handle the rest.
The reading-order table below lists every book with per-volume reading level and intensity badges so you can spot any escalation before it catches your reader off guard. For a deeper dive into how we score text difficulty vs. emotional weight separately — and why series readers especially benefit from that split — see our methodology page.
