The activity, titled '3-Card Trick,' challenges learners to identify all possible combinations of three cards from a given set of playing cards that sum to a specific target number, such as 12 or 15. By working through these combinatorial exercises, students improve their mental arithmetic, pattern recognition, and logical thinking. The document includes both the problem set and the corresponding solution key, providing a comprehensive tool for classroom instruction or independent study. The content is structured to encourage systematic exploration of number combinations, making it an excellent exercise for elementary and early middle-school students focusing on foundational number theory concepts. Through the engaging premise of a card trick, it transforms basic addition into an investigative task that fosters deeper mathematical understanding.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/3-card-trick-mathematics-practice-worksheet/635310/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/3-card-trick-mathematics-practice-worksheet/635310.png","ImageObject",300,407,{"name":92,"@type":93},"Chumphorn","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-22",true,{"@type":102,"interactionType":103,"userInteractionCount":24},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the goal of the 3-card trick activity?","Question",{"text":112,"@type":113},"The goal is to identify all possible combinations of three cards from the provided set that add up to a specified target sum, such as 12 or 15.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What are the card combinations for a sum of 12?",{"text":117,"@type":113},"The possible combinations are 8+3+1, 6+5+1, 6+4+2, and 5+4+3.",{"name":119,"@type":110,"acceptedAnswer":120},"What are the card combinations for a sum of 15?",{"text":121,"@type":113},"The possible combinations are 8+6+1, 8+5+2, 8+4+3, and 6+5+4.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},635310,1792942314,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":24,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":14,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":143,"read_time":24},2336475401981,"https://ap-avatar.wpscdn.com/avatar/22000c94efd8d5204d?x-image-process=image/resize,m_fixed,w_180,h_180&k=1786935347598174694","Name  \n3-CARD TRICK  \nDate  \nFlame salamander has chosen 3 cards from the pile below for a card trick.  \nShe says that the cards she has chosen make a total of 12.  \nWhich cards could she have chosen?
