The document features eighteen distinct problems, each requiring the student to calculate the unknown variable that completes the given total. By practicing these missing number exercises, young learners improve their foundational mathematical skills, mental addition capabilities, and algebraic thinking. The worksheet includes an answer key at the bottom to facilitate self-assessment and review for students and educators alike. This resource is an excellent tool for classroom practice or home-based supplemental learning, focusing on precision and logical number deduction in primary mathematics education.",{"@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-add-4-single-digit-numbers-with-missing-values/545035/",{"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-add-4-single-digit-numbers-with-missing-values/545035.png","ImageObject",300,407,{"name":92,"@type":93},"Eliana","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-08","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 primary objective is to help second-grade students practice addition by finding missing addends in equations consisting of four single-digit numbers.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many addition problems are included in this document?",{"text":117,"@type":113},"There are eighteen individual addition problems provided in this worksheet.",{"name":119,"@type":110,"acceptedAnswer":120},"Is there a way to verify the solutions to these math problems?",{"text":121,"@type":113},"Yes, an answer key is provided at the bottom of the document, listing the correct missing number for each of the eighteen 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},545035,1791773663,{"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","Add 4 single-digit numbers – missing number   \nGrade 2 Addition Worksheet  \nFind the missing numbers:  \n1) 4 + 9 + 2 +   = 21 2) 5 + 8 +   + 5 = 22 3) 4 + 9 + 5 +   = 20  \n4) 8 + 6 +   + 2 = 21 5) 7 +   + 6 + 7 = 29 6) 5 + 2 +   + 6 = 21  \n7) 4 +   + 5 + 4 = 18 8) 9 + 4 +   + 7 = 28 9) 3 +   + 5 + 3 = 19  \n10) 8 + 4 + 4 +   = 24 11) 7 + 6 + 2 +   = 21 12) 8 +   + 8 + 8 = 30  \n13) 5 + 2 + 8 +   = 21 14) 6 + 4 + 8 +   = 21 15) 1 + 5 + 7 +   = 15  \n16) 9 + 1 +   + 2 = 14 17) 8 +   + 2 + 6 = 20 18)   + 7 + 7 + 2 = 18  \nAnswers  \n1) 6 2) 4 3) 2  \n4) 5 5) 9 6) 8  \n7) 5 8) 8 9) 8  \n10) 8 11) 6 12) 6  \n13) 6 14) 3 15) 2  \n16) 2 17) 4 18) 2","cbCaihnTSQO9r5KH","https://ap.wps.com/l/cbCaihnTSQO9r5KH","pdf",27590,"English","# Missing Number Addition Exercises\n## Answer Key","[{\"question\":\"What is the primary objective of this worksheet?\",\"answer\":\"The primary objective is to help second-grade students practice addition by finding missing addends in equations consisting of four single-digit numbers.\"},{\"question\":\"How many addition problems are included in this document?\",\"answer\":\"There are eighteen individual addition problems provided in this worksheet.\"},{\"question\":\"Is there a way to verify the solutions to these math problems?\",\"answer\":\"Yes, an answer key is provided at the bottom of the document, listing the correct missing number for each of the eighteen problems.\"}]","Grade 2 Addition Worksheet - Add 4 Single-Digit Numbers with Missing Values | PDF"]
