However, there are some students who are not good at \"addition and subtraction of fractions\" because they cannot find the \"least common multiple\" quickly and appropriately. In particular, some students seem to believe that the least common multiple of two integers is the product of the two numbers. Therefore, teachers must consider how to help students visually understand the least common multiples of two integers that are not relatively prime, by \"decomposing a number into the product of the two numbers\" and \"recognizing the product of the two numbers as the number of blocks\"，before learning \"addition and subtraction of fractions\" .","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"高松大学・高松短期大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12458238","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-1786","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"土井, 理裕"}],"nameIdentifiers":[{"nameIdentifier":"8770","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-01-27"}],"displaytype":"detail","filename":"79_UK003_001-013_doi.pdf","filesize":[{"value":"721.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"79_UK003_001-013_doi.pdf","url":"https://takamatsu-u.repo.nii.ac.jp/record/6570/files/79_UK003_001-013_doi.pdf"},"version_id":"d5512899-d713-4c33-ae06-54dec49fec5a"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"小学校算数における最小公倍数の指導法について －互いに素でない２つの整数の最小公倍数を視覚的に理解させる－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"小学校算数における最小公倍数の指導法について －互いに素でない２つの整数の最小公倍数を視覚的に理解させる－"},{"subitem_title":"Teaching Method of the Least Common Multiple in Elementary School Mathematics：Visually understand methods of the least common multiple of two integers that are not relatively prime","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["5798"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-01-31"},"publish_date":"2023-01-31","publish_status":"0","recid":"6570","relation_version_is_last":true,"title":["小学校算数における最小公倍数の指導法について －互いに素でない２つの整数の最小公倍数を視覚的に理解させる－"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-19T10:08:10.492567+00:00"}
