One chart, five grades. Start by feeling and hearing sounds, learn to tell them apart, catch how English spells them, build words from meaning-pieces — and only at Grade 5 do the scientific symbols and names unlock. Choose a grade to begin.

This chart connects to what you're learning.

Every symbol here is a sound your lessons teach you to feel, hear and say first — the chart simply gives it a name once you've earned it. Pick a sound and learn it with the tutor, or build it yourself in the Sound Lab by changing one feature at a time.
