The primary objective is to find missing addends in equations involving 2-digit numbers and whole tens. The document presents eighteen distinct problems, designed to challenge students' mental math capabilities and their understanding of numerical relationships. Each problem requires the student to determine the unknown value that completes the mathematical equality, providing a comprehensive practice set for developing addition proficiency. Additionally, the document includes a complete answer key at the bottom to facilitate self-assessment and educational feedback, making it an ideal resource for teachers and parents looking to support elementary-level students in mastering foundational addition operations and algebraic thinking in a structured format.",{"@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-whole-tens-to-2-digit-numbers-missing-addend-worksheet/548411/",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-whole-tens-to-2-digit-numbers-missing-addend-worksheet/548411.png","ImageObject",300,407,{"name":42,"@type":43},"\tCallum
