The document includes both a practice version and a completed answer key, serving as a valuable resource for elementary school students to reinforce their addition skills, number sense, and algebraic thinking. Each problem requires students to calculate the difference between the sum and the given addend, effectively testing their ability to perform subtraction as the inverse of addition. The structured format is ideal for classroom instruction, homework assignments, or supplementary home practice to ensure numerical fluency in early mathematics.",{"@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/grade-2-addition-worksheet-missing-addend-sums-under-20/546577/",{"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/grade-2-addition-worksheet-missing-addend-sums-under-20/546577.png","ImageObject",300,407,{"name":92,"@type":93},"Riley","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-03","2026-10-12",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the primary objective of this worksheet?","Question",{"text":112,"@type":113},"The worksheet aims to help Grade 2 students practice addition by identifying missing numbers in equations with sums up to 20.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many problems are included in the worksheet?",{"text":117,"@type":113},"There are 20 individual addition problems provided for practice.",{"name":119,"@type":110,"acceptedAnswer":120},"Does the document provide solutions?",{"text":121,"@type":113},"Yes, the second page of the document contains the completed equations with all missing addends filled in.","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},546577,1791777376,{"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":29,"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":129,"read_time":24,"preview_page_count":4},1374391975076,"https://ap-avatar.wpscdn.com/avatar/14000253ca4ec9f6853?x-image-process=image/resize,m_fixed,w_180,h_180&k=1783305029341752051","Addition-missing addend (sums up to 20)   \nGrade 2 Addition Worksheet  \nFill in the missing numbers.  \n1)   + 3 = 15 2) 11 +   = 18  \n3)   + 17 = 20 4) 13 +   = 16  \n5) 10 +   = 16 6)   + 2 = 13  \n7)   + 6 = 13 8)   + 15 = 18  \n9) 9 +   = 11 10)   + 2 = 5  \n11) 6 +   = 9 12) 7 +   = 10  \n13)   + 3 = 8 14)   + 4 = 16  \n15)   + 5 = 10 16)   + 17 = 19  \n17)   + 6 = 20 18) 4 +   = 14  \n19)   + 15 = 19 20) 7 +   = 18  \nAddition-missing addend (sums up to 20)   \nGrade 2 Addition Worksheet  \nFill in the missing numbers.  \n1)  12  + 3 = 15 2) 11 +  7  = 18  \n3)  3  + 17 = 20 4) 13 +  3  = 16  \n5) 10 +  6  = 16 6)  11  + 2 = 13  \n7)  7  + 6 = 13 8)  3  + 15 = 18  \n9) 9 +  2  = 11 10)  3  + 2 = 5  \n11) 6 +  3  = 9 12) 7 +  3  = 10  \n13)  5  + 3 = 8 14)  12  + 4 = 16  \n15)  5  + 5 = 10 16)  2  + 17 = 19  \n17)  14  + 6 = 20 18) 4 +  10  = 14  \n19)  4  + 15 = 19 20) 7 +  11  = 18","cbCainXFdTwwf93U","https://ap.wps.com/l/cbCainXFdTwwf93U","pdf",44688,"English","# Missing Addend Problems\n## Answer Key","[{\"question\":\"What is the primary objective of this worksheet?\",\"answer\":\"The worksheet aims to help Grade 2 students practice addition by identifying missing numbers in equations with sums up to 20.\"},{\"question\":\"How many problems are included in the worksheet?\",\"answer\":\"There are 20 individual addition problems provided for practice.\"},{\"question\":\"Does the document provide solutions?\",\"answer\":\"Yes, the second page of the document contains the completed equations with all missing addends filled in.\"}]","Grade 2 Addition Worksheet - Missing Addend Sums Under 20 | PDF"]
