The document provides 20 distinct arithmetic problems designed to strengthen algebraic thinking and numerical fluency in elementary students. By requiring the calculation of unknown values within addition expressions, the worksheet reinforces foundational arithmetic skills and logical reasoning. This resource serves as an effective practice tool for educators and students to improve speed and accuracy in basic math operations. The clear, repetitive structure allows for consistent skill-building and self-assessment, making it highly suitable for classroom activities, homework assignments, or supplemental math practice at home. Each problem encourages students to apply addition strategies efficiently, facilitating better command over number relationships and mental computation techniques suitable for the fourth-grade curriculum.",{"@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/mental-math-missing-numbers-grade-4-addition-worksheet/545964/",{"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/mental-math-missing-numbers-grade-4-addition-worksheet/545964.png","ImageObject",300,407,{"name":92,"@type":93},"Ezra","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 goal of this worksheet?","Question",{"text":112,"@type":113},"The goal is to improve mental math skills by finding the missing addends in addition problems where the sum is under 100.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What grade level is this worksheet designed for?",{"text":117,"@type":113},"This worksheet is specifically designed for Grade 4 students.",{"name":119,"@type":110,"acceptedAnswer":120},"How many math problems are included in this worksheet?",{"text":121,"@type":113},"There are 20 addition problems in total, each requiring the student to solve for a missing number.","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},545964,1791775846,{"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},1099514068035,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","Mental math: missing numbers (sum under  100)   \nGrade 4 Addition Worksheet  \nFind the missing number.  \n1.   + 26 = 85 2.   + 49 = 83  \n3. 31 +   = 42 4. 35 +   = 52  \n5. 89 + 18 =   6. 22 +   = 87  \n7.   + 36 = 82 8. 28 + 26 =    \n9. 11 +   = 68 10. 40 + 12 =    \n11. 44 +   = 90 12. 36 +   = 70  \n13. 25 +   = 96 14.   + 29 = 92  \n15. 35 +   = 92 16.   + 25 = 75  \n17. 66 + 24 =   18.   + 14 = 100  \n19. 86 + 11 =   20. 3 + 81 =    \nMental math: missing numbers (sum under  100)   \nGrade 4 Addition Worksheet  \nFind the missing number.  \n1.  59  + 26 = 85 2.  34  + 49 = 83  \n3. 31 +  11  = 42 4. 35 +  17  = 52  \n5. 89 + 18 =  107  6. 22 +  65  = 87  \n7.  46  + 36 = 82 8. 28 + 26 =  54   \n9. 11 +  57  = 68 10. 40 + 12 =  52   \n11. 44 +  46  = 90 12. 36 +  34  = 70  \n13. 25 +  71  = 96 14.  63  + 29 = 92  \n15. 35 +  57  = 92 16.  50  + 25 = 75  \n17. 66 + 24 =  90  18.  86  + 14 = 100  \n19. 86 + 11 =  97  20. 3 + 81 =  84","cbCaiirJdRVYRvBl","https://ap.wps.com/l/cbCaiirJdRVYRvBl","pdf",13319,"English","# Addition Practice\n## Missing Number Exercises","[{\"question\":\"What is the goal of this worksheet?\",\"answer\":\"The goal is to improve mental math skills by finding the missing addends in addition problems where the sum is under 100.\"},{\"question\":\"What grade level is this worksheet designed for?\",\"answer\":\"This worksheet is specifically designed for Grade 4 students.\"},{\"question\":\"How many math problems are included in this worksheet?\",\"answer\":\"There are 20 addition problems in total, each requiring the student to solve for a missing number.\"}]","Mental Math - Missing Numbers - Grade 4 Addition Worksheet | PDF"]
