Questions SLPs ask

How many /th/ words should I practice in a session?

Aim for many quick repetitions: 50 to 100 productions in a 30-minute session is a common target for articulation drill, spread across a small set of words.

Should I start with initial, medial or final /th/?

Most SLPs start with the position the student finds easiest (often initial), then add the others. Follow the student's stimulability and the IEP goal.

Can I get these /th/ words as a printable worksheet?

Yes. PrepPal turns a /th/ goal into a printable worksheet with pictures, picture cards and digital drill cards in seconds. The first one is free.
