A set of math problem books and answer explanations for home study for 3rd graders in the 2022 academic year. These are problems for summer home study from the Mabuchi Kyōshitsu junior high school entrance exam course. They are divided by date, and I think they can be used not only during summer vacation but also for daily morning study. Basically, there is no writing, but there are pages where writing has been erased and pages with some damage. Please check the photos attached. The part with the name will be either blacked out or cut out before shipping. - Year: 2022 - Grade: 3rd grade - Subject: Home Study - Problem Book: Math - Format: Answers and Explanations Thank you for looking.
