The document features a series of exercises focused on adding three addends, each consisting of whole hundreds. By providing a structured list of twenty addition problems, the worksheet encourages students to improve their speed and accuracy in basic arithmetic operations. The inclusion of an answer key allows students to self-assess their progress, making it an excellent tool for classroom instruction, homework assignments, or independent study at home. This resource emphasizes foundational mathematical competency, helping students build confidence in mental calculation and number sense through consistent practice and repetitive learning patterns, which are essential for developing stronger quantitative abilities at the elementary education level.",{"@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-4-addition-worksheet-adding-whole-hundreds-3-addends/545946/",{"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-4-addition-worksheet-adding-whole-hundreds-3-addends/545946.png","ImageObject",300,407,{"name":92,"@type":93},"Ezra","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-05","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 primary focus of this worksheet?","Question",{"text":112,"@type":113},"The primary focus is practicing mental math by adding three whole hundreds numbers together.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Who is the target audience for this document?",{"text":117,"@type":113},"This worksheet is designed for grade 4 students.",{"name":119,"@type":110,"acceptedAnswer":120},"Are the answers included in the document?",{"text":121,"@type":113},"Yes, the document includes a section that provides the correct sums for all twenty addition 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},545946,1791775803,{"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},1099514068035,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","Mental math: adding whole hundreds  \n (3 addends)   \nGrade 4 Addition Worksheet  \nFind the sum.  \n1. 500 + 900 + 200 =   2. 400 + 700 + 200 =   3. 300 + 300 + 500 =   4. 300 + 300 + 400 =   5. 200 + 700 + 100 =   6. 200 + 200 + 500 =   7. 200 + 900 + 400 =   8. 900 + 500 + 500 =   9. 700 + 900 + 300 =   10. 400 + 600 + 300 =   11. 800 + 700 + 100 =   12. 100 + 200 + 200 =   13. 900 + 200 + 400 =   14. 200 + 600 + 900 =   15. 600 + 700 + 900 =   16. 600 + 200 + 100 =   17. 600 + 600 + 800 =   18. 700 + 800 + 700 =    \n19. 800 + 600 + 500 =   20. 700 + 700 + 700 =    \nMental math: adding whole hundreds  \n (3 addends)   \nGrade 4 Addition Worksheet  \nFind the sum.  \n1. 500 + 900 + 200 =  1,600  2. 400 + 700 + 200 =  1,300   \n3. 300 + 300 + 500 =  1,100  4. 300 + 300 + 400 =  1,000   \n5. 200 + 700 + 100 =  1,000  6. 200 + 200 + 500 =  900   \n7. 200 + 900 + 400 =  1,500  8. 900 + 500 + 500 =  1,900   \n9. 700 + 900 + 300 =  1,900  10. 400 + 600 + 300 =  1,300   \n11. 800 + 700 + 100 =  1,600  12. 100 + 200 + 200 =  500   \n13. 900 + 200 + 400 =  1,500  14. 200 + 600 + 900 =  1,700   \n15. 600 + 700 + 900 =  2,200  16. 600 + 200 + 100 =  900   \n17. 600 + 600 + 800 =  2,000  18. 700 + 800 + 700 =  2,200   \n19. 800 + 600 + 500 =  1,900  20. 700 + 700 + 700 =  2,100","cbCaisqzYskBjR4C","https://ap.wps.com/l/cbCaisqzYskBjR4C","pdf",14472,"English","# Mental Math Exercises\n## Answer Key","[{\"question\":\"What is the primary focus of this worksheet?\",\"answer\":\"The primary focus is practicing mental math by adding three whole hundreds numbers together.\"},{\"question\":\"Who is the target audience for this document?\",\"answer\":\"This worksheet is designed for grade 4 students.\"},{\"question\":\"Are the answers included in the document?\",\"answer\":\"Yes, the document includes a section that provides the correct sums for all twenty addition problems.\"}]","Grade 4 Addition Worksheet - Adding Whole Hundreds - 3 Addends | PDF"]
