It includes two identical pages, with one page serving as a worksheet and the other offering a complete answer key for reference. The worksheet features 20 distinct arithmetic problems aimed at improving students' speed and accuracy in mental calculation. By practicing these sums, students can reinforce their foundational addition skills and build confidence in handling multi-digit arithmetic operations without relying on written long-form methods. The content is suitable for classroom practice, homework assignments, or supplementary learning at home to support the Grade 4 mathematics 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-adding-two-2-digit-numbers-grade-4-addition-worksheet/545856/",{"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-adding-two-2-digit-numbers-grade-4-addition-worksheet/545856.png","ImageObject",300,407,{"name":92,"@type":93},"Oliver","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-12",true,{"@type":102,"interactionType":103,"userInteractionCount":14},"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 Grade 4 students practice and improve their ability to mentally add two 2-digit numbers.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many problems are included in this addition worksheet?",{"text":117,"@type":113},"There are 20 addition problems in total provided for the students to solve.",{"name":119,"@type":110,"acceptedAnswer":120},"Does the document provide the answers to the addition problems?",{"text":121,"@type":113},"Yes, the document includes a version of the worksheet with the solutions for all 20 arithmetic problems provided.","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},545856,1791775620,{"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":14,"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},8796095461610,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","Mental math: adding two 2-digit numbers   \nGrade 4 Addition Worksheet  \nFind the sum.  \n1. 23 + 45 =   2. 37 + 77 =   3. 24 + 62 =   4. 13 + 10 =   5. 92 + 7 =   6. 9 + 33 =   7. 69 + 43 =   8. 74 + 70 =   9. 46 + 34 =   10. 10 + 20 =   11. 44 + 15 =   12. 36 + 70 =   13. 18 + 15 =   14. 39 + 35 =   15. 11 + 76 =   16. 89 + 13 =   17. 93 + 49 =   18. 49 + 57 =    \n19. 83 + 38 =   20. 82 + 74 =    \nMental math: adding two 2-digit numbers   \nGrade 4 Addition Worksheet  \nFind the sum.  \n1. 23 + 45 =  68  2. 37 + 77 =  114   \n3. 24 + 62 =  86  4. 13 + 10 =  23   \n5. 92 + 7 =  99  6. 9 + 33 =  42   \n7. 69 + 43 =  112  8. 74 + 70 =  144   \n9. 46 + 34 =  80  10. 10 + 20 =  30   \n11. 44 + 15 =  59  12. 36 + 70 =  106   \n13. 18 + 15 =  33  14. 39 + 35 =  74   \n15. 11 + 76 =  87  16. 89 + 13 =  102   \n17. 93 + 49 =  142  18. 49 + 57 =  106   \n19. 83 + 38 =  121  20. 82 + 74 =  156","cbCaiivP3hiYVnK6","https://ap.wps.com/l/cbCaiivP3hiYVnK6","pdf",12932,"English","# Mental Math Addition Worksheet\n## Answer Key","[{\"question\":\"What is the primary objective of this worksheet?\",\"answer\":\"The primary objective is to help Grade 4 students practice and improve their ability to mentally add two 2-digit numbers.\"},{\"question\":\"How many problems are included in this addition worksheet?\",\"answer\":\"There are 20 addition problems in total provided for the students to solve.\"},{\"question\":\"Does the document provide the answers to the addition problems?\",\"answer\":\"Yes, the document includes a version of the worksheet with the solutions for all 20 arithmetic problems provided.\"}]","Mental Math - Adding Two 2-Digit Numbers - Grade 4 Addition Worksheet | PDF"]
