Hello Ms. Sasha
My Name is Marissa, For the child nonverbal, you can use more children interactions where she participates, making rotations with different verbal children. Other thing when you work on individual, you can make more face and body expressions to motivate the child interest (smile, dance, jumping, etc.). In daily class each comment, show book pictures, or information use clearly and slow pronunciations all the time. Questions to other children and she them, you need to give trust and make constantly.
Thank you!
