The exercises focus on column addition without regrouping, requiring learners to identify the unknown addend to complete each equation. By working through these problems, students reinforce their foundational arithmetic skills, improve their understanding of place value, and develop fluency in basic addition operations. This educational material is suitable for primary school learners aiming to build confidence in solving missing variable math problems in a structured, column-based format.",{"@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-1-addition-worksheet-missing-addend-2-digit-numbers/546198/",{"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-1-addition-worksheet-missing-addend-2-digit-numbers/546198.png","ImageObject",300,407,{"name":92,"@type":93},"Theodore","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 skill does this worksheet focus on?","Question",{"text":112,"@type":113},"This worksheet focuses on adding two-digit numbers in columns with a missing addend, specifically without the need for regrouping.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Who is the target audience for these exercises?",{"text":117,"@type":113},"The target audience is Grade 1 students who are learning foundational addition and place value concepts.",{"name":119,"@type":110,"acceptedAnswer":120},"How are the problems presented in this document?",{"text":121,"@type":113},"The problems are presented as column addition exercises where students must solve for an unknown number to complete the equation.","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},546198,1791776471,{"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},7971461740886,"https://ap-avatar.wpscdn.com/davatar_3d24733baf745e90a7e4bdd5f77d97b2","Add two 2-digit numbers in columns, missing  addend (no regrouping)   \nGrade 1 Addition Worksheet  \nFind the missing number.  \n+ 10  \n51  \n+ 13 99  \n13) 10 + 79  \n17) 84 + 0  \n+ 21  \n65  \n10) 80  \n\n| + |  |\n| --- | --- |\n\n93  \n+ 21  \n 67  \n18) 60 + 16  \n7) 17 + 71  \n11) 10  \n\n| + |  |\n| --- | --- |\n\n20  \n15) 0 + 76  \n+ 20  \n88  \n8) 57  \n\n| + |  |\n| --- | --- |\n\n88  \n12) 33  \n+ 21  \n16) 67  \n\n| + |  |\n| --- | --- |\n\n78  \n20) 11  \n+ 50  \nAdd two 2-digit numbers in columns, missing  addend (no regrouping)   \nGrade 1 Addition Worksheet  \nFind the missing number.  \n1) 11 + 34  \n5) 41  \n+ 10  \n51  \n9) 86  \n+ 13  \n99  \n13) 10 + 79  \n17) 84 + 0  \n2) 87 + 11  98  \n6) 44  \n+ 21  \n65  \n10) 80  \n\n| + | 13 |\n| --- | --- |\n\n93  \n14) 46  \n+ 21  \n67  \n18) 60 + 16  \n3) 83 + 1  \n7) 17 + 71  \n11) 10  \n\n| + | 10 |\n| --- | --- |\n\n20  \n15) 0 + 76  \n19) 68 + 20 88  \n4) 20  \n+ 40  \n60  \n8) 57  \n\n| + | 31 |\n| --- | --- |\n\n88  \n12) 33  \n+ 21  \n16) 67  \n\n| + | 11 |\n| --- | --- |\n\n78  \n20) 11  \n+ 50","cbCaiov112YhjkBV","https://ap.wps.com/l/cbCaiov112YhjkBV","pdf",13324,"English","# Addition Practice Problems\n## 2-Digit Addition Exercises","[{\"question\":\"What skill does this worksheet focus on?\",\"answer\":\"This worksheet focuses on adding two-digit numbers in columns with a missing addend, specifically without the need for regrouping.\"},{\"question\":\"Who is the target audience for these exercises?\",\"answer\":\"The target audience is Grade 1 students who are learning foundational addition and place value concepts.\"},{\"question\":\"How are the problems presented in this document?\",\"answer\":\"The problems are presented as column addition exercises where students must solve for an unknown number to complete the equation.\"}]","Grade 1 Addition Worksheet - Missing Addend 2-Digit Numbers | PDF"]
