Each exercise presents an equation with one missing addend, requiring learners to apply mental math skills and basic addition strategies to determine the correct value. The document features eighteen distinct problems ranging in complexity, followed by a comprehensive answer key at the end to facilitate self-assessment and independent learning. Designed for second-grade students, this material effectively reinforces place value understanding and numerical fluency through consistent practice of adding multiples of ten. The structure is clear and sequential, making it an ideal supplementary resource for classroom instruction or home practice sessions focused on elementary mathematics mastery.",{"@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/adding-3-whole-tens-missing-number-grade-2-addition-worksheet/545048/",{"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/adding-3-whole-tens-missing-number-grade-2-addition-worksheet/545048.png","ImageObject",300,407,{"name":92,"@type":93},"Eliana","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-05","2026-10-12",true,{"@type":102,"interactionType":103,"userInteractionCount":81},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the purpose of this worksheet?","Question",{"text":112,"@type":113},"The worksheet is designed to help second-grade students practice adding three whole tens to find a missing number in an addition equation.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many problems are included in this worksheet?",{"text":117,"@type":113},"There are 18 math problems included, along with a complete answer key for checking results.",{"name":119,"@type":110,"acceptedAnswer":120},"What specific math skill is being practiced?",{"text":121,"@type":113},"The document focuses on adding three multiples of ten, requiring students to solve for a missing addend in equations that result in a three-digit or two-digit sum.","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},545048,1791773679,{"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":81,"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) 80 + 90 +   = 200  \n4) 90 + 80 +   = 180  \n7) 90 + 10 +   = 130  \n10) 70 +   + 50 = 160  \n13) 30 + 90 +   = 180  \n16)   + 60 + 10 = 160  \n2) 50 +   + 70 = 170  \n5)   + 50 + 50 = 140  \n8) 10 + 60 +   = 80  \n11) 20 +   + 80 = 110  \n14) 40 + 20 +   = 120  \n17)   + 80 + 90 = 260  \n3)   + 90 + 80 = 190  \n6) 60 + 40 +   = 120  \n9)   + 50 + 50 = 130  \n12) 20 +   + 30 = 80  \n15)   + 50 + 10 = 120  \n18)   + 80 + 50 = 190  \nAnswers  \n1) 30 2) 50 3) 20  \n4) 10 5) 40 6) 20  \n7) 30 8) 10 9) 30  \n10) 40 11) 10 12) 30  \n13) 60 14) 60 15) 60  \n16) 90 17) 90 18) 60","cbCaitgKuCJO95lz","https://ap.wps.com/l/cbCaitgKuCJO95lz","pdf",27784,"English","# Adding 3 Whole Tens - Missing Number\n## Practice Exercises\n## Answer Key","[{\"question\":\"What is the purpose of this worksheet?\",\"answer\":\"The worksheet is designed to help second-grade students practice adding three whole tens to find a missing number in an addition equation.\"},{\"question\":\"How many problems are included in this worksheet?\",\"answer\":\"There are 18 math problems included, along with a complete answer key for checking results.\"},{\"question\":\"What specific math skill is being practiced?\",\"answer\":\"The document focuses on adding three multiples of ten, requiring students to solve for a missing addend in equations that result in a three-digit or two-digit sum.\"}]","Adding 3 Whole Tens - Missing Number - Grade 2 Addition Worksheet | PDF"]
