[Sách] Pearson Abacus Year 2 Workbook 1 – Sách giấy gáy xoắn

This book was bought as a gift for a friend’s daughter. She was doing online classes. I looked through this book before I gave it to her and it was laid out very well. She even had room to work problems in the book. I was very satisfied with this book and would order another one if needed.
