Eikaiwa teachers: Phonics for kids

Hey, fellow teachers/educators. I’m a strong advocate of phonics instruction. Because of a literacy course I recently took, I even became more interested in it after having a better understanding of The Simple View of Reading, Scarborough Reading Rope, etc.

For eikaiwa teachers, does your eikaiwa have phonics classes/phonics instruction? What materials/books do you use/ have you used (if you can share)? Also, what age do you think is appropriate for kids to start learning single phonics? Is Kinder 2 (年中) too early to expect them to learn the single phonics, to learn blending, and eventually be able to write?

For ALTs, could you share at what grade level do kids learn phonics (if they do at all)?

Thanks as always! Happy to learn from others here.
