Another question: You mentioned that your son went to Aloha (Soroban math school). Mine started last week, he just turned 4 and he entered the Jr. L1. They were reluctant to accept him in the beginning because of his "young age", though we do math at a 2nd grade level at home. They tested him and were pretty surprised by his math abilities.
During his first session, he would just write down the answer if the tutor is standing by him. He wouldn't finish the rest by himself. So they advised me to bring him back in a year or so when he's "emotionally ready"

. I was so disappointed and suggested he may need more time to get used to it. Did you have a similar problem when you started Aloha? Do you have ideas to get him more motivated to finish his worksheets by himself (He wasn't impressed by Aloha Dollars last time

)
Also, how frequently did you practice Soroban (in addition to the required homework)?
Thank you.
