It provides students with a series of addition problems where one addend is exactly one less than the other, encouraging the use of doubles facts as a foundation for mental math. By using the provided example as a guide—where a student computes 5 + 4 by first adding 5 + 5 and then subtracting 1—the worksheet helps reinforce fundamental arithmetic proficiency. The document includes a clear list of practice exercises followed by a dedicated section containing the correct answers for each problem. Designed for primary level learners, this resource aims to bridge the gap between simple counting and more complex mental arithmetic strategies, fostering number sense and speed in basic addition. The systematic approach supports independent practice and classroom learning environments, making it an essential tool for developing foundational math skills in early elementary education.",{"@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/adding-doubles-minus-1-grade-1-addition-worksheet/550698/",{"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/adding-doubles-minus-1-grade-1-addition-worksheet/550698.png","ImageObject",300,407,{"name":92,"@type":93},"Aditya","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-06","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 'adding doubles minus 1' strategy?","Question",{"text":112,"@type":113},"It is a mental math strategy where you add the larger number to itself and then subtract 1, as shown in the example 5 + 4 = 5 + 5 - 1 = 9.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Who is this worksheet designed for?",{"text":117,"@type":113},"This worksheet is designed for Grade 1 students to practice basic addition skills.",{"name":119,"@type":110,"acceptedAnswer":120},"Does the document provide answers?",{"text":121,"@type":113},"Yes, the document includes a section specifically providing the answers for all the addition problems listed.","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},550698,1791786153,{"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},962085564549,"https://ap-avatar.wpscdn.com/davatar_085a072bc5b1113ac321206ff7593b45","Adding doubles minus 1  \nGrade 1 Addition Worksheet  \nAdd doubles less 1 to find each sum:  \nExample: 5 + 4 = 5 + 5-1 = 10-1 = 9  \n8 + 7 =  \n9 + 8 =  \n2 + 1 =  \n7 + 6 =  \n4 + 3 =  \n3 + 2 =  \n6 + 5 =  \n10 + 9 =  \n6 + 5 =  \n1 + 0 =  \n4 + 3 =  \n1 + 0 =  \n5 + 4 =  \n3 + 2 =  \n9 + 8 =  \nAdding doubles minus 1  \nGrade 1 Addition Worksheet  \nAnswers  \n8 + 7 =  \n9 + 8 =  \n2 + 1 =  \n7 + 6 =  \n4 + 3 =  \n15  \n17  \n3  \n3 + 2 =  \n6 + 5 =  \n10 + 9 =  \n6 + 5 =  \n1 + 0 =  \n5  \n11  \n19  \n4 + 3 =  \n1 + 0 =  \n5 + 4 =  \n3 + 2 =  \n9 + 8 =  \n7  \n1  \n9","cbCaiu79iWxd2xOQ","https://ap.wps.com/l/cbCaiu79iWxd2xOQ","pdf",12468,"English","# Adding Doubles Minus 1 Exercises\n## Answer Key","[{\"question\":\"What is the 'adding doubles minus 1' strategy?\",\"answer\":\"It is a mental math strategy where you add the larger number to itself and then subtract 1, as shown in the example 5 + 4 = 5 + 5 - 1 = 9.\"},{\"question\":\"Who is this worksheet designed for?\",\"answer\":\"This worksheet is designed for Grade 1 students to practice basic addition skills.\"},{\"question\":\"Does the document provide answers?\",\"answer\":\"Yes, the document includes a section specifically providing the answers for all the addition problems listed.\"}]","Adding Doubles Minus 1 - Grade 1 Addition Worksheet | PDF"]
