Designed for young students, the content features eighteen distinct algebraic-style problems where learners must identify the missing term in simple addition equations involving multiples of ten. By engaging with these specific arithmetic exercises, students reinforce their foundational understanding of place value and addition properties. The document also includes a complete answer key, serving as a valuable tool for parents, teachers, or students to perform self-assessments and track progress in early elementary arithmetic skill-building. The worksheet is presented in a clear, accessible format conducive to classroom settings or independent home study, emphasizing accuracy and numerical fluency in basic addition operations.",{"@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-1-addition-worksheet-adding-whole-tens-missing-addend/545009/",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-1-addition-worksheet-adding-whole-tens-missing-addend/545009.png","ImageObject",300,407,{"name":42,"@type":43},"Eliana","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-03","2026-10-12",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",5,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the primary objective of this worksheet?","Question",{"text":63,"@type":64},"The objective is for students to find the missing addends in addition equations involving whole tens.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"What is the format of the math problems provided?",{"text":68,"@type":64},"The problems are presented as simple addition equations where one of the addends is left blank, requiring the student to calculate the missing value to reach the given sum.",{"name":70,"@type":61,"acceptedAnswer":71},"Are the solutions included in the document?",{"text":72,"@type":64},"Yes, a comprehensive answer key is provided at the end of the document, listing the correct missing number for each of the eighteen 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},545009,1791773603,{"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":55,"preview_page_count":4},4398048949847,"https://ap-avatar.wpscdn.com/avatar/400002536579ef2da7f?_k=1778318612642679267","Adding whole tens – missing addend   \nGrade 1 Addition Worksheet  \nFind the missing numbers:  \n1)   + 20 = 100 2)   + 50 = 140 3)   + 60 = 130  \n4)   + 70 = 130 5)   + 60 = 100 6)   + 80 = 130  \n7) 60 +   = 90 8)   + 40 = 130 9) 30 +   = 80  \n10) 80 +   = 90 11)   + 70 = 160 12)   + 10 = 40  \n13) 90 +   = 150 14)   + 10 = 30 15) 90 +   = 100  \n16) 30 +   = 70 17) 90 +   = 110 18)   + 50 = 70  \nAnswers  \n1) 80 2) 90 3) 70  \n4) 60 5) 40 6) 50  \n7) 30 8) 90 9) 50  \n10) 10 11) 90 12) 30  \n13) 60 14) 20 15) 10  \n16) 40 17) 20 18) 20","cbCaig59X8xLhu0H","https://ap.wps.com/l/cbCaig59X8xLhu0H","pdf",27555,"English","# Adding Whole Tens -
