Hi Does anybody have used the pre-school Math books set by Time Life?
http://www.educationaltechnologies.com/products/learning_math_with_albertMy son is already 4 years old. He doesn't like counting even when we're using his toys as props nor he likes sorting sets even if we're dealing with his cars. Then, I came upon this book set that really looks enticing. I already have bought their Knowledge books set which my son really likes and enjoys but I want to know from other parents who have bought the math set if it is indeed effective and appropriate for his age. It's quite costly about USD600 so I want to research before actually buying it.
