Chiba Lotte Marines published the "The Marines Math Drills Reiwa 7 Winter Edition" and distributed it free of charge to 109 public elementary schools in Chiba City. Also, today, the 16th (Tuesday), as part of the activities of the social contribution project "MARINES LINKS", Atsuya Hirohata pitcher visited Tsuga Elementary School in Chiba City, where a presentation ceremony for The Marines Math Workbook was held with all 429 students in attendance.

At the end of the presentation ceremony, pitcher Hirohata sent a message to the children, saying, "The fun winter break will soon begin, but first I would like you to study using the math workbooks that we distributed today. The 'drill' in math workbooks is like the drill used to dig a hole; you dig the hole little by little by going around in circles. In the same way, work hard at your studies. And enjoy your winter break to the fullest. Thank you for today."

The Marines Math Drill is a self-study material made up of questions related to Chiba Lotte Marines and baseball, developed with the cooperation of the NPO Chiba Math and Mathematics Association. This marks the 43rd edition since distribution began in 2011. The Winter 2025 edition was created as a review material for the content learned up to December. Players have been visiting schools since 2011, and presentation ceremonies were canceled in 2020 and 2021 due to the spread of COVID-19, but have resumed in 2022.

"The math workbook that we gave to the children this time features the players, and in speech bubbles, they give hints to the answers, but Kyodai (Kyota Fujiwara) says some really difficult things, and I thought, 'Kyota Fujiwara would never say something like that!' I personally thought it was a very interesting teaching material (laughs). I think the content is a really well-made workbook, so I would like the children to make good use of it. I myself will continue to work hard, little by little, and do my best to do well next season."
