Designed for early elementary students, the document includes thirty mixed arithmetic problems requiring learners to solve for missing operands or identify the result of operations. Additionally, it features a challenge section that tasks students with finding two numbers based on specified sum and difference criteria. A comprehensive answer key is included at the end to assist with self-evaluation and facilitate independent learning progress in fundamental mathematical skills.",{"@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/add-and-subtract-within-20-sheet-6-practice-exercises/632961/",{"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/add-and-subtract-within-20-sheet-6-practice-exercises/632961.png","ImageObject",300,407,{"name":92,"@type":93},"River Wang","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-31","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 primary focus of this document?","Question",{"text":112,"@type":113},"The document focuses on practicing addition and subtraction operations for numbers within the range of 20.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many problems are included in the main practice sheet?",{"text":117,"@type":113},"There are 30 problems in the main practice sheet, covering a variety of addition and subtraction equations.",{"name":119,"@type":110,"acceptedAnswer":120},"What is the objective of the 'Challenge' section?",{"text":121,"@type":113},"The challenge section asks students to determine two specific numbers that satisfy both a given total (sum) and a given difference.","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},632961,1792985003,{"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},1099514067438,"https://ap-avatar.wpscdn.com/avatar/100002539ee87300030?x-image-process=image/resize,m_fixed,w_180,h_180&k=1780474512215547542","ADD AND SUBTRACT WITHIN 20 SHEET 6  \n1) 7 + 11 =   16) 9 +   = 14  \n2) 20 – 16 =   17) 18 ̶   = 12  \n3) 13 + 4 =   18) 6 +   = 13  \n4) 17 – 6 =   19) 14 ̶   = 9  \n5) 19 – 8 =   20)   + 6 = 20  \n6) 9 + 5 =   21)   ̶ 3 = 12  \n7) 8 + 12 =   22)   + 4 = 16  \n8) 18 – 11 =   23)   ̶ 6 = 9  \n9) 6 + 9 =   24) 13 +   = 17  \n10) 15 – 13 =   25) 15 ̶   = 8  \n11) 20 – 8 =   26)   + 12 = 17  \n12) 3 + 15 =   27)   ̶ 8 = 11  \n13) 11 + 5 =   28) 4 +   = 16  \n14) 19 – 14 =   29) 19 ̶   = 5  \n15) 7 + 13 =   30)   ̶ 7 = 9  \nCHALLENGE – TOTAL AND DIFFERENCE  \n1) Find two numbers with a total of 16 and a difference of 4:   and    \n2) Find two numbers with a total of 19 and a difference of 3:   and    \n3) Find two numbers with a total of 18 and a difference of 8:   and    \nADD AND SUBTRACT WITHIN 20 SHEET 6 ANSWERS  \n1)  \n2)  \n3)  \n4)  \n5)  \n6)  \n7)  \n8)  \n9)  \n10)  \n11)  \n12)  \n13)  \n14)  \n15)  \n7 + 11 = 18 20 – 16 = 4  \n13 + 4 = 17  \n17 – 6 = 11  \n19 – 8 = 11  \n9 + 5 = 14 8 + 12 = 20 18 – 11 = 7  \n6 + 9 = 15 15 – 13 = 2  \n20 – 8 = 12  \n3 + 15 = 18  \n11 + 5 = 16  \n19 – 14 = 5  \n7 + 13 = 20  \n16)  \n17)  \n18)  \n19)  \n20)  \n21)  \n22)  \n23)  \n24)  \n25)  \n26)  \n27)  \n28)  \n29)  \n30)  \n9 + 5 = 14  \n18 ̶ 6 = 12  \n6 + 7 = 13  \n14 ̶ 5 = 9 14 + 6 = 20 15 ̶ 3 = 12 12 + 4 = 16 15 ̶ 6 = 9  \n13 + 4 = 17  \n15 ̶ 7 = 8 5 + 12 = 17 19 ̶ 8 = 11  \n4 + 12 = 16  \n19 ̶ 14 = 5 16 ̶ 7 = 9  \nCHALLENGE – TOTAL AND DIFFERENCE  \n\n| 1) | Find two numbers with a total of 16 and a difference of 4:  10 | and | 6 |\n| --- | --- | --- | --- |\n| 2) | Find two numbers with a total of 19 and a difference of 3:  11 | and | 8 |\n| 3) | Find two numbers with a total of 18 and a difference of 8:  13 | and | 5 |","cbCaimphUxY2MvKP","https://ap.wps.com/l/cbCaimphUxY2MvKP","pdf",177034,"English","# Addition and Subtraction Practice\n## Challenge -
