Kumon English G II Materials - Some Numbers Missing 1-40 51-90 101-140 151-190 11-40 61-90 101-130 151-160 21-40 71-80 There are some gaps in the pages, so please consider this for reviewing areas where you struggle! These materials were used by my child several years ago and are all used. There is pencil writing and red pen grading. I will ship them as they are, without erasing anything. I will erase the name with a marker or correction tape. I think they are in relatively good condition. Please understand that these are used items. Please refrain from canceling after purchase. Thank you. Immediate purchase is OK. *Regarding Kumon materials, due to the weight, I cannot offer a discount for combined purchases. I apologize for this.
