Juku (Cram School) Textbook: New Elementary School Workbook, Grade 4, Mathematics, Keirinkan "Elementary School Mathematics" Textbook-Aligned This is a textbook for a cram school for 4th graders. Since it's from before the revision, there might be some differences in content compared to the current latest textbooks. Please be aware of this if you need the latest version. As it is aligned with the textbook, the difficulty level is not high. I think it can be used for both previewing the next grade and reviewing the current grade. ■ Textbook ■ 12 Review Tests ■ Answer Key There are many writings in it (see photos 3 and 4). I have erased the writings of the child as much as possible, but I apologize if I missed anything. Please be aware of this if you are sensitive to such things or are looking for a pristine item.
