Includes an explanation booklet. I had two copies of the math textbook at home, so I'm selling one. For the past few years, the content of the ena textbooks seems to be the same. I hope you can use this to solidify your fundamentals and identify areas where you struggle. *I am also selling the 3 subjects (Math, Japanese, English) together. https://jp.mercari.com/item/m66276149002 Please consider this as well. (It was possible to choose only the 3 subjects at the time.) *Regarding ena's summer course fees: For the highest level class (which should be cheaper than the standard class), this year it is 47,960 yen for 5 subjects for 1st graders. (Approximately 10,000 yen per subject) Get the materials at a low price and take a look. If your child can study at home, it will give you peace of mind. If you have any questions, please feel free to ask.
