Pygmalion Grade II ① Early Childhood Math (II) - Sequel to the previous book, "Math for 2-Year-Olds" Understanding numbers from 1 to 10 and developing calculation skills for addition and subtraction up to 20. I made copies and used them, so it's almost unused. ② Developing Thinking Skills / Dot-to-Dot ① - This is a book. Developing spatial reasoning and understanding relationships in 2D space. I made copies and used them, so it's almost unused. I will also include other dot-to-dot exercises (printouts) that I received for practice in the classroom. ③ Developing Thinking Skills / Number of Blocks I made copies and used them, so it's almost unused. ④ Developing Thinking Skills / Math Workbook / Numbers and Calculations I made copies and used them, so it's almost unused.
