The document explains the concept through an illustrative example: 5 + 4 is calculated as (5 + 5) - 1 = 9. Following this methodology, the worksheet includes a series of addition exercises designed to reinforce mental math skills and arithmetic fluency. By breaking down the addition process, students develop a deeper understanding of number relationships and basic operations. The document includes a comprehensive set of answer keys, facilitating self-assessment and teacher evaluation. It is an essential resource for primary school educators and parents seeking to support first-grade learners in mastering foundational addition concepts through targeted practice. The clear layout ensures that students can focus on the logic behind each calculation, gradually improving their confidence and speed in solving increasingly complex sums.",{"@graph":14,"@context":73},[15,34,56],{"@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/adding-doubles-minus-1-grade-1-addition-worksheet/550695/",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/adding-doubles-minus-1-grade-1-addition-worksheet/550695.png","ImageObject",300,407,{"name":42,"@type":43},"Aditya","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-13","2026-10-12",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",6,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is the 'doubles minus 1' strategy?","Question",{"text":63,"@type":64},"The 'doubles minus 1' strategy involves using a known double to solve an addition problem, then subtracting one from the result.
