[100% 영어] Read Think Speak! 짧은 읽기, 깊은 토론
My child says that having discussion classes with various friends is more fun than just simple 1:1 video English lessons. They mentioned that the teacher allowed the children to speak freely and provided equal opportunities for everyone to participate. There are also 1:1 discussion sessions in the Zoom breakout rooms. While debating is where they struggle compared to native speakers, I think consistent practice will be helpful for students aspiring to attend foreign language high schools or international high schools. Even though they weren't feeling well yesterday after taking medicine for a cold, they said they had fun after class. They even diligently scribbled down the writing assignment the teacher gave them (which they wouldn't do if their mom asked them to), so I've attached the homework for you. Oh, and thank you for the discount coupon after class!

처음 읽기에 딱! 말문 트이는 리더스북 16권 완독 프로젝트
My child said they felt comfortable and really enjoyed it because the teacher guided them in a relaxed manner and helped them read with confidence. Watching them preview the vocabulary together, take turns reading, and review the content through questions, I watched in admiration, thinking, "They will truly understand Book 1." Writing the book report wasn't easy for them, but thanks to the excellent guidance, it was great to see them writing it down. I was also touched again to see them read properly after the teacher commented to read the book three times and try shadowing to bring out the intonation.🤩 They usually wouldn't listen and were stubborn when I told them to, but this was amazing!🤣 See you again tomorrow!

[AR 2,0~3,2] 읽기 속도 정체를 깨는 탐정 미션 수업 Nate the Great 시리즈
Today was our fifth lesson, and I am so grateful to you, teacher. I started these classes because I felt it was time for a new approach to English reading, and the results have been excellent. Before we read the book during class, you provide essential information related to the content beforehand, which helps us understand the book much better. My child says that because we read with concentration during class and repeat the homework multiple times, their skills seem to have improved even before we started. We are also diligently completing the reading homework five times a week. We will keep working hard until the end of the Nate series!
