The document provides a structured set of fourteen mathematical problems that require students to calculate the sum of three given numbers and identify the fourth value necessary to reach the specified total. By focusing on whole tens, the worksheet reinforces mental math proficiency, number sense, and algebraic thinking for early elementary learners. The resource includes a comprehensive answer key at the bottom, allowing for immediate self-correction or teacher verification. It serves as an effective learning tool for classroom instruction, supplemental home practice, or remedial support, helping students build confidence in multi-addend addition operations and fundamental arithmetic reasoning.",{"@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/545050/",{"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/545050.png","ImageObject",300,407,{"name":92,"@type":93},"Eliana","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-04","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 primary objective of this worksheet?","Question",{"text":112,"@type":113},"The worksheet aims to help second-grade students practice adding four whole tens and solving for a missing addend within a given equation.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many problems are included in the exercise?",{"text":117,"@type":113},"There are 14 distinct addition problems provided for the student to solve.",{"name":119,"@type":110,"acceptedAnswer":120},"Is an answer key provided for this worksheet?",{"text":121,"@type":113},"Yes, a complete answer key is included at the end of the document to assist with grading and verification of the calculations.","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},545050,1791773684,{"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 4 whole tens – missing number   \nGrade 2 Addition Worksheet  \nFind the missing numbers:  \n1) 70 + 80 +   + 20 = 180 2) 80 + 40 + 30 +   = 190  \n3) 40 +   + 50 + 60 = 230 4) 60 + 60 +   + 60 = 200  \n5) 60 + 60 +   + 10 = 170 6) 40 +   + 30 + 40 = 120  \n7) 60 +   + 50 + 10 = 180 8) 60 + 70 + 80 +   = 260  \n9) 90 +   + 60 + 10 = 190 10) 20 + 30 + 20 +   = 120  \n11) 80 + 90 + 90 +   = 330 12) 40 +   + 80 + 90 = 220  \n13) 40 + 40 +   + 90 = 190 14)   + 50 + 40 + 60 = 210  \nAnswers  \n1) 10 2) 40  \n3) 80 4) 20  \n5) 40 6) 10  \n7) 60 8) 50  \n9) 30 10) 50  \n11) 70 12) 10  \n13) 20 14) 60","cbCais0Ig06bqp8u","https://ap.wps.com/l/cbCais0Ig06bqp8u","pdf",27401,"English","# Missing Number Problems\n## Answer Key","[{\"question\":\"What is the primary objective of this worksheet?\",\"answer\":\"The worksheet aims to help second-grade students practice adding four whole tens and solving for a missing addend within a given equation.\"},{\"question\":\"How many problems are included in the exercise?\",\"answer\":\"There are 14 distinct addition problems provided for the student to solve.\"},{\"question\":\"Is an answer key provided for this worksheet?\",\"answer\":\"Yes, a complete answer key is included at the end of the document to assist with grading and verification of the calculations.\"}]","Grade 2 Addition Worksheet - Adding Whole Tens - Missing Numbers | PDF"]
