The document features eighteen structured problems that encourage learners to identify the unknown value in an equation, helping them build foundational arithmetic skills, improve mental calculation proficiency, and understand the relationship between numbers and operations. Each problem is carefully crafted to reinforce addition techniques using multiples of ten, providing a clear and logical progression for students to practice and master basic algebraic thinking. The worksheet concludes with an answer key, making it an excellent tool for independent study, classroom practice, or supplemental homework support, ensuring that students can self-assess their progress and accuracy in solving multi-step mathematical problems involving whole numbers.",{"@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-missing-addend-grade-1-math-worksheet/545007/",{"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-missing-addend-grade-1-math-worksheet/545007.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 objective of this worksheet?","Question",{"text":112,"@type":113},"The objective is to help first-grade students practice finding missing addends in addition problems involving whole tens.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many problems are included in the worksheet?",{"text":117,"@type":113},"There are 18 individual addition problems provided for students to solve.",{"name":119,"@type":110,"acceptedAnswer":120},"Is there an answer key available?",{"text":121,"@type":113},"Yes, the document includes a complete list of answers at the bottom for verification and self-assessment.","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},545007,1791773598,{"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 whole tens – missing addend   \nGrade 1 Addition Worksheet  \nFind the missing numbers:  \n1)   + 90 = 170 2) 40 +   = 110 3) 20 +   = 60  \n4) 90 +   = 180 5)   + 20 = 70 6)   + 40 = 110  \n7)   + 30 = 80 8) 90 +   = 130 9) 90 +   = 100  \n10) 30 +   = 100 11)   + 70 = 160 12)   + 60 = 130  \n13) 50 +   = 100 14) 10 +   = 100 15) 50 +   = 70  \n16) 10 +   = 50 17)   + 20 = 100 18)   + 40 = 90  \nAnswers  \n1) 80 2) 70 3) 40  \n4) 90 5) 50 6) 70  \n7) 50 8) 40 9) 10  \n10) 70 11) 90 12) 70  \n13) 50 14) 90 15) 20  \n16) 40 17) 80 18) 50","cbCaioz7E8gjDTNB","https://ap.wps.com/l/cbCaioz7E8gjDTNB","pdf",27468,"English","# Addition Practice Problems\n## Answer Key","[{\"question\":\"What is the objective of this worksheet?\",\"answer\":\"The objective is to help first-grade students practice finding missing addends in addition problems involving whole tens.\"},{\"question\":\"How many problems are included in the worksheet?\",\"answer\":\"There are 18 individual addition problems provided for students to solve.\"},{\"question\":\"Is there an answer key available?\",\"answer\":\"Yes, the document includes a complete list of answers at the bottom for verification and self-assessment.\"}]","Adding Whole Tens - Missing Addend - Grade 1 Math Worksheet | PDF"]
