The lesson explains the method through an example: rounding 194 up to 200, adding mentally, then subtracting the extra amount to correct the result. A set of 20 two-number addition problems is provided for learners to solve using this strategy, followed by an answer key listing the correct sums.",{"@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-use-rounding-strategies-to-find-the-sum/464871/",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-use-rounding-strategies-to-find-the-sum/464871.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":30},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58],{"name":59,"@type":60,"acceptedAnswer":61},"Where can the correct results be found?","Question",{"text":62,"@type":63},"An answer key section lists 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},464871,1790768834,{"code":4,"msg":73,"data":74},"success",{"doc_id":70,"user_id":75,"nickname":42,"user_avatar":76,"doc_module":4,"category_id":33,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":77,"file_id":78,"file_url":79,"file_type":80,"file_size":81,"view_count":30,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":30,"language":82,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":83,"faqs":84,"seo_title":85,"seo_description":12,"update_tm":71,"read_time":86},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.
