Students are provided with a series of addition problems where one addend is exactly one less than the other, encouraging the use of mental math by relating these problems to known double sums. The document includes clear instructional examples showing how to transform expressions like 5+4 into 5+5-1 to arrive at the solution. By practicing these repetitive patterns, learners build foundational confidence in number sense, addition fluency, and algebraic thinking. The worksheet concludes with an answer key section to facilitate self-assessment or parent-led grading, making it an effective tool for classroom supplement or home practice. The material is designed specifically for early elementary education to strengthen basic numeracy skills through structured, consistent, and logical mathematical exercises.",{"@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-1-addition-worksheet-adding-doubles-minus-1-practice-exercises/550696/",{"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-1-addition-worksheet-adding-doubles-minus-1-practice-exercises/550696.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 'doubles minus 1' strategy for addition?","Question",{"text":112,"@type":113},"The strategy involves identifying a problem where one addend is one less than the other (e.g., 5 + 4), recognizing that it is equivalent to the double of the larger number minus one (5 + 5 - 1), which simplifies to 10 - 1 = 9.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"Who is this worksheet intended for?",{"text":117,"@type":113},"This worksheet is specifically designed for Grade 1 students who are learning foundational addition skills and mental math strategies.",{"name":119,"@type":110,"acceptedAnswer":120},"Does the document provide solutions to the problems?",{"text":121,"@type":113},"Yes, the document includes a dedicated answer key section that provides the results for all the addition problems listed on the worksheet.","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},550696,1791786151,{"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  \n5 + 4 =  \n6 + 5 =  \n4 + 3 =  \n8 + 7 =  \n4 + 3 =  \n1 + 0 =  \n10 + 9 =  \n9 + 8 =  \n2 + 1 =  \n8 + 7 =  \n3 + 2 =  \n7 + 6 =  \n2 + 1 =  \n7 + 6 =  \n3 + 2 =  \nAdding doubles minus 1  \nGrade 1 Addition Worksheet  \nAnswers  \n5 + 4 =  \n6 + 5 =  \n4 + 3 =  \n8 + 7 =  \n4 + 3 =  \n9  \n11  \n7  \n1 + 0 =  \n10 + 9 =  \n9 + 8 =  \n2 + 1 =  \n8 + 7 =  \n1  \n19  \n17  \n3 + 2 =  \n7 + 6 =  \n2 + 1 =  \n7 + 6 =  \n3 + 2 =  \n5  \n13  \n3","cbCaiqXpVxp8Esz6","https://ap.wps.com/l/cbCaiqXpVxp8Esz6","pdf",12519,"English","# Adding Doubles Minus 1 Worksheet\n## Addition Practice Exercises\n## Answer Key","[{\"question\":\"What is the 'doubles minus 1' strategy for addition?\",\"answer\":\"The strategy involves identifying a problem where one addend is one less than the other (e.g., 5 + 4), recognizing that it is equivalent to the double of the larger number minus one (5 + 5 - 1), which simplifies to 10 - 1 = 9.\"},{\"question\":\"Who is this worksheet intended for?\",\"answer\":\"This worksheet is specifically designed for Grade 1 students who are learning foundational addition skills and mental math strategies.\"},{\"question\":\"Does the document provide solutions to the problems?\",\"answer\":\"Yes, the document includes a dedicated answer key section that provides the results for all the addition problems listed on the worksheet.\"}]","Grade 1 Addition Worksheet - Adding Doubles Minus 1 - Practice Exercises | PDF"]
