The worksheet presents 14 distinct problems that require students to apply algebraic thinking to identify the missing value required to reach the target sum. By engaging with these problems, students reinforce their foundational arithmetic skills, improve their number sense, and practice basic algebraic solving techniques. The document also includes an answer key at the bottom, making it a valuable resource for teachers and parents to use for classroom instruction, homework assignments, or supplementary home-based tutoring to enhance computational fluency in young learners.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/grade-2-addition-worksheet-missing-addend-exercises/548353/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/grade-2-addition-worksheet-missing-addend-exercises/548353.png","ImageObject",300,407,{"name":42,"@type":43},"\tCallum ","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-05","2026-10-12",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",7,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the primary focus of this worksheet?","Question",{"text":63,"@type":64},"The worksheet focuses on practicing addition for second-grade students, specifically involving the addition of a 2-digit number and three 1-digit numbers with one missing addend.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"How many problems are included in this worksheet?",{"text":68,"@type":64},"There are 14 problems provided in the worksheet, each requiring the student to find a missing number to complete the equation.",{"name":70,"@type":61,"acceptedAnswer":71},"Is an answer key provided?",{"text":72,"@type":64},"Yes, the document includes a complete answer key at the bottom to help verify the solutions for all 14 problems.","https://schema.org",{"og:url":32,"og:type":75,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":77,"canonical":32},"index,follow",{"doc_id":79,"site_id":7},548353,1791781707,{"code":4,"msg":82,"data":83},"success",{"doc_id":79,"user_id":84,"nickname":42,"user_avatar":85,"doc_module":4,"category_id":33,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":86,"file_id":87,"file_url":88,"file_type":89,"file_size":90,"view_count":55,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":26,"language":91,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":92,"faqs":93,"seo_title":94,"seo_description":12,"update_tm":80,"read_time":95,"preview_page_count":4},137451211410,"https://ap-avatar.wpscdn.com/avatar/2000bb0a9246f588df?x-image-process=image/resize,m_fixed,w_180,h_180&k=1786362646172706240","Add 2-digit and three 1-digit numbers (missing addend)   \nGrade 2 Addition Worksheet  \nFind the missing numbers:  \n1) 7 + 2 + 6 +   = 86 2)   + 78 + 2 + 6 = 91  \n3)   + 2 + 5 + 6 = 56 4) 4 +   + 3 + 35 = 45  \n5)   + 6 + 8 + 50 = 67 6) 2 + 2 + 7 +   = 109  \n7) 5 + 2 + 9 +   = 112 8) 15 + 4 +   + 3 = 29  \n9) 4 + 7 +   + 50 = 69 10) 54 + 6 + 8 +   = 73  \n11)   + 7 + 9 + 7 = 51 12)   + 8 + 7 + 6 = 58  \n13)   + 7 + 7 + 5 = 113 14) 33 +   + 6 + 4 = 50  \nAnswers  \n1) 71 2) 5  \n3) 43 4) 3  \n5) 3 6) 98  \n7) 96 8) 7  \n9) 8 10) 5  \n11) 28 12) 37  \n13) 94 14) 7","cbCaiiVkvskKhn6y","https://ap.wps.com/l/cbCaiiVkvskKhn6y","pdf",19966,"English","# Addition Practice Exercises\n## Missing Addend Problems\n## Answer Key","[{\"question\":\"What is the primary focus of this worksheet?\",\"answer\":\"The worksheet focuses on practicing addition for second-grade students, specifically involving the addition of a 2-digit number and three 1-digit numbers with one missing addend.\"},{\"question\":\"How many problems are included in this worksheet?\",\"answer\":\"There are 14 problems provided in the worksheet, each requiring the student to find a missing number to complete the equation.\"},{\"question\":\"Is an answer key provided?\",\"answer\":\"Yes, the document includes a complete answer key at the bottom to help verify the solutions for all 14 problems.\"}]","Grade 2 Addition Worksheet -
