[What is your Singapore Schedule?]

Could I insert another question? I am fairly new to Singapore. The only books I have been using are the textbooks and workbook. I was unaware of the IP (what is that?) and the Challenging Word Problems. Are they for extra practice, or do they take the math lessons to another level? In other words - if she is "getting" the material from the text and workbooks, do I need to add these other books?

[What to do with 9 year old after Latina Christiana?]

My daughter will be finishing Latina Christiana I in a few weeks. I am planning move her right into LCII and would expect to finish sometime next fall. At that time she will be 9 1/2 years old and in 5th grade. Should I move her on to Henle, or will the grammer be too advanced for her?
