The primary objective of the worksheet is to help students practice the concept of identifying the predecessor of a given number, specifically ranging from 1 to 20. Through a sequence of twenty problems, students are challenged to determine the value that is exactly one less than a provided integer. The layout includes a numerical grid from 1 to 20 to assist with counting and visual reference, reinforcing foundational number sense and subtraction concepts. The material is suitable for classroom practice or homework assignments focused on early-stage numeracy development, encouraging students to improve their speed and accuracy in performing simple subtraction tasks. Each exercise follows a clear format, ensuring consistent pedagogical application throughout the lesson.",{"@graph":14,"@context":72},[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/one-less-math-worksheet-9-practice-exercises/637008/",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/one-less-math-worksheet-9-practice-exercises/637008.png","ImageObject",300,407,{"name":42,"@type":43},"Alexandar","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-22",true,{"@type":52,"interactionType":53,"userInteractionCount":30},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What
