The exercise requires students to determine the unknown component in addition equations where one part is a multiple of ten. By engaging with these eighteen distinct problems, young learners reinforce their understanding of decimal base systems and basic addition skills. A complete answer key is provided at the end of the document to facilitate self-assessment and teacher evaluation, making it an excellent resource for classroom practice or home-based tutoring to solidify foundational arithmetic proficiency and number sense development.",{"@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-whole-tens-and-ones-missing-addend-grade-1/545013/",{"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-whole-tens-and-ones-missing-addend-grade-1/545013.png","ImageObject",300,407,{"name":92,"@type":93},"Eliana","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-07","2026-10-12",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the objective of this worksheet?","Question",{"text":112,"@type":113},"The objective is for Grade 1 students to practice finding missing addends in addition problems involving whole tens and ones.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many problems are included in this worksheet?",{"text":117,"@type":113},"There are 18 individual problems provided for students to solve.",{"name":119,"@type":110,"acceptedAnswer":120},"Is there a way to check the answers?",{"text":121,"@type":113},"Yes, a complete answer key for all 18 problems is provided at the bottom of the worksheet.","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},545013,1791773609,{"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":29,"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 whole tens and ones – missing addend   \nGrade 1 Place Value Worksheet  \nFind the missing numbers:  \n1) 9 +   = 49 2) 49 = 40 +   3) 5 +   = 15  \n4) 20 +   = 22 5) 90 +   = 91 6) 20 = 20 +    \n7) 60 +   = 63 8) 15 = 10 +   9) 20 = 0 +    \n10) 44 = 40 +   11) 39 =  + 9 12)   + 6 = 16  \n13) 55 =  + 50 14) 59 = 50 +   15) 11 = 10 +    \n16)   + 60 = 65 17) 60 +   = 66 18)   + 80 = 86  \nAnswers  \n1) 40 2) 9 3) 10  \n4) 2 5) 1 6) 0  \n7) 3 8) 5 9) 20  \n10) 4 11) 30 12) 10  \n13) 5 14) 9 15) 1  \n16) 5 17) 6 18) 6","cbCaimHgPDpY8jxf","https://ap.wps.com/l/cbCaimHgPDpY8jxf","pdf",27486,"English","# Missing Addend Problems\n## Answer Key","[{\"question\":\"What is the objective of this worksheet?\",\"answer\":\"The objective is for Grade 1 students to practice finding missing addends in addition problems involving whole tens and ones.\"},{\"question\":\"How many problems are included in this worksheet?\",\"answer\":\"There are 18 individual problems provided for students to solve.\"},{\"question\":\"Is there a way to check the answers?\",\"answer\":\"Yes, a complete answer key for all 18 problems is provided at the bottom of the worksheet.\"}]","Adding Whole Tens and Ones - Missing Addend Grade 1 | PDF"]
