Thank you for viewing. This is a calculation drill material that comes with Shichida's elementary school print math for 3rd graders. There are 10 books in total, with 10 to 11 days' worth of material in each book. It includes addition and subtraction from 36 to 100 squares, as well as 100-square multiplication. One sheet per day provides approximately 3 months' worth of material. It's an amount that allows for the consolidation of basic skills without being a burden. Calculation ability is the foundation of math, so how about it for your child? Please see the photos for the contents of the calculation drill. ☆ This is an appendix to the math print, which has a list price of 18,000 yen. How about 1,500 yen including shipping? Only the first page of the first book is filled in, and I will remove it before sending. The other pages are blank and in good condition.
