深化学习的研究课 — 二年级数学与社会科公开课
5月26日（星期二），二年级的教室里举行了研究课。第3节课，二年4班开展了数学课「联立方程式的解法」；第5节课，二年3班开展了社会科课「交通的发展与三都的繁荣」。
数学课以"求苹果和橘子的价格"这一贴近生活的问题为切入点，引导学生思考通过"消去"未知数来求解联立方程式这一核心方法。学生们在小组交流中认真面对**"用小学生也能听懂的方式说明"**这一课题，在图示与算式之间来回比对，用自己的语言整理出解题思路。
社会科课聚焦于江户时代的五街道与三都（江户、大阪、京都）的发展。学生们通过阅读地图和资料，思考大名、商人、飞脚分别为何前往江户，理解交通的发展如何促进了人与物的流通。这也是一堂让学生重新认识自己生活的大阪——曾作为"天下厨房"与日本各地紧密相连的历史的课。
两堂课都充分运用了电子白板，在呈现图示、资料以及共享学生想法的环节中发挥了重要作用。学生们以视觉化整理的信息为基础，深入思考自己的观点，并与同学的意见相互碰撞，让学习不断走向深处。
每节课结束后，我们邀请了大阪市综合教育中心的柏木顾问到校，对两堂课进行了指导与建议。为了让日常的课堂越来越好，全体教师将继续学习、不断精进。我们将作为**"团队北稜"**，持续为支撑学生的学习而用心打磨每一堂课。

Deepening Learning Through Research Lessons — Year 8 Maths and Social Studies
On Tuesday, 26 May, research lessons were held in our Year 8 classrooms. During Period 3, Class 2-4 opened a mathematics lesson on solving simultaneous equations, and during Period 5, Class 2-3 opened a social studies lesson on "The Development of Transport and the Prosperity of the Three Cities."
The mathematics lesson began with a familiar problem — finding the price of apples and oranges — as a gateway into the core idea of solving simultaneous equations by "eliminating" a variable. Through group discussion, students engaged with the challenge of "explaining it so that even a primary school pupil could understand," moving back and forth between diagrams and equations to put the solving process into their own words.
The social studies lesson focused on the Five Highways of the Edo period and the development of the three great cities — Edo, Osaka, and Kyoto. Reading maps and historical materials, students considered why daimyo, merchants, and couriers each travelled towards Edo, and explored how the growth of transport networks expanded the movement of people and goods. It was also a chance to rediscover the history of Osaka — their own home city — as the "Kitchen of the Nation," once linked to every corner of Japan.
In both lessons, the electronic blackboard was used effectively, playing an important role in displaying diagrams and materials and in sharing students' ideas. With information organised visually, students deepened their own thinking while weaving in the perspectives of their classmates.
After each lesson, we welcomed Adviser Kashiwagi from the Osaka City Educational Centre, who kindly offered guidance and feedback on both classes. To keep improving the everyday classroom, all of our teachers will continue to learn and grow. As "Team Hokuryō," we will keep dedicating ourselves to shaping lessons that truly support our students' learning.
