The document presents 18 distinct arithmetic problems where students must solve for an unknown addend within equations involving sums of tens. By providing both the exercise questions and a comprehensive answer key, the material serves as an effective resource for independent practice, classroom assessment, or remedial learning to strengthen foundational computational proficiency in young learners. The exercises are structured to build confidence in mental math and algebraic thinking by requiring the student to balance simple equations.",{"@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-adding-whole-tens-missing-numbers/545042/",{"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-adding-whole-tens-missing-numbers/545042.png","ImageObject",300,407,{"name":92,"@type":93},"Eliana","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-06","2026-10-12",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 main objective of this worksheet?","Question",{"text":112,"@type":113},"The main objective is to practice addition of three whole tens to find a missing number in a series of equations.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many practice problems are included in this worksheet?",{"text":117,"@type":113},"There are 18 distinct arithmetic problems provided for students to solve.",{"name":119,"@type":110,"acceptedAnswer":120},"Does this document include the solutions?",{"text":121,"@type":113},"Yes, a complete answer key is provided at the bottom of the worksheet for all 18 problems.","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},545042,1791773673,{"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":129,"read_time":24,"preview_page_count":4},4398048949847,"https://ap-avatar.wpscdn.com/avatar/400002536579ef2da7f?_k=1778318612642679267","Adding 3 whole tens – missing number   \nGrade 2 Addition Worksheet  \nFind the missing numbers:  \n1) 60 +   + 80 = 220  \n4) 20 +   + 90 = 140  \n7) 80 + 90 +   = 220  \n10) 60 + 80 +   = 210  \n13) 40 +   + 50 = 110  \n16) 80 +   + 30 = 150  \n2)   + 80 + 20 = 190  \n5) 10 + 70 +   = 130  \n8) 70 +   + 70 = 230  \n11) 50 + 30 +   = 110  \n14) 40 +   + 80 = 160  \n17) 80 +   + 30 = 120  \n3) 20 + 90 +   = 160  \n6) 20 +   + 30 = 70  \n9) 30 +   + 70 = 130  \n12)   + 80 + 60 = 190  \n15)   + 50 + 30 = 110  \n18) 50 +   + 90 = 230  \nAnswers  \n1) 80 2) 90 3) 50  \n4) 30 5) 50 6) 20  \n7) 50 8) 90 9) 30  \n10) 70 11) 30 12) 50  \n13) 20 14) 40 15) 30  \n16) 40 17) 10 18) 90","cbCaiirsbKvDStEA","https://ap.wps.com/l/cbCaiirsbKvDStEA","pdf",27778,"English","# Addition Practice Problems\n## Missing Number Equations\n# Answer Key","[{\"question\":\"What is the main objective of this worksheet?\",\"answer\":\"The main objective is to practice addition of three whole tens to find a missing number in a series of equations.\"},{\"question\":\"How many practice problems are included in this worksheet?\",\"answer\":\"There are 18 distinct arithmetic problems provided for students to solve.\"},{\"question\":\"Does this document include the solutions?\",\"answer\":\"Yes, a complete answer key is provided at the bottom of the worksheet for all 18 problems.\"}]","Grade 2 Addition Worksheet - Adding Whole Tens - Missing Numbers | PDF"]
