The document provides a structured set of twenty practice problems designed to reinforce addition fluency with multiples of ten. By requiring learners to mentally aggregate four distinct addends, the worksheet encourages efficient number sense and rapid calculation skills. It serves as an essential resource for educators and parents aiming to support primary school students in mastering fundamental arithmetic operations through consistent, targeted practice and evaluation. Each exercise is presented clearly, enabling students to track their progress while building confidence in handling multi-addend problems in a sequential, manageable format suitable for daily classroom or home study.",{"@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-4-addition-worksheet-mental-math-adding-whole-tens-practice-exercises/545956/",{"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-4-addition-worksheet-mental-math-adding-whole-tens-practice-exercises/545956.png","ImageObject",300,407,{"name":92,"@type":93},"Ezra","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-02","2026-10-12",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What
