It demonstrates rounding one addend to the highest place value, solving the simplified problem, and then adjusting for the amount added or subtracted during rounding. The worksheet includes 20 problems in the form of two numbers to add, followed by an answer key that verifies each sum. Practice focuses on efficient estimation and correction rather than aligning place values.",{"@graph":14,"@context":64},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/finding-sum-with-rounding-round-to-the-highest-place-value-mental-addition-practice/464878/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/finding-sum-with-rounding-round-to-the-highest-place-value-mental-addition-practice/464878.png","ImageObject",300,407,{"name":42,"@type":43},"Emma Wilson","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-09-30",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58],{"name":59,"@type":60,"acceptedAnswer":61},"Where can learners find the correct results for the 20 problems?","Question",{"text":62,"@type":63},"The document includes an answer key listing the sums for problems 1 through 20.","Answer","https://schema.org",{"og:url":32,"og:type":66,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":68,"canonical":32},"index,follow",{"doc_id":70,"site_id":7},464878,1790768847,{"code":4,"msg":73,"data":74},"success",[75,79,83,86,91,96,101,106,111,114,118],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":76,"show_sort_weight":77,"slug":78},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":80,"show_sort_weight":81,"slug":82},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":84,"slug":85},70,"exam",{"id":87,"doc_module":4,"doc_module_name":25,"category_name":88,"show_sort_weight":89,"slug":90},5,"Comic",60,"comic",{"id":92,"doc_module":4,"doc_module_name":25,"category_name":93,"show_sort_weight":94,"slug":95},6,"Technology",50,"technology",{"id":97,"doc_module":4,"doc_module_name":25,"category_name":98,"show_sort_weight":99,"slug":100},7,"Healthcare",40,"healthcare",{"id":102,"doc_module":4,"doc_module_name":25,"category_name":103,"show_sort_weight":104,"slug":105},8,"Research & Report",30,"research-report",{"id":107,"doc_module":4,"doc_module_name":25,"category_name":108,"show_sort_weight":109,"slug":110},9,"Religion & Spirituality",20,"religion-spirituality",{"id":109,"doc_module":4,"doc_module_name":25,"category_name":112,"show_sort_weight":109,"slug":113},"World Cup","world-cup",{"id":115,"doc_module":4,"doc_module_name":25,"category_name":116,"show_sort_weight":115,"slug":117},10,"Lifestyle","lifestyle",{"id":119,"doc_module":4,"doc_module_name":25,"category_name":120,"show_sort_weight":87,"slug":121},19,"General","general",{"code":4,"msg":73,"data":123},{"doc_id":70,"user_id":124,"nickname":42,"user_avatar":125,"doc_module":4,"category_id":33,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":126,"file_id":127,"file_url":128,"file_type":129,"file_size":130,"view_count":33,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":30,"language":131,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":132,"faqs":133,"seo_title":134,"seo_description":12,"update_tm":71,"read_time":102},3848291630094,"https://eur-avatar.wpscdn.com/davatar_085a072bc5b1113ac321206ff7593b45","Finding Sum with Rounding  \nName:  \n\n| Use rounding strategies to find the sum.\u003Cbr>\u003Cbr> Now we can mentally add and find the \u003Cbr>Rather than lining up the place values, one strategy is to round to the highest place value and solve mentally.\u003Cbr>194 + 236 =\u003Cbr>In the example above 194 rounds up to 200.
