The document consists of two main parts: a worksheet containing 30 problems for students to solve, and a corresponding answer key to facilitate self-assessment. Each problem requires adding a multiple of ten to a base number, encouraging students to recognize the underlying pattern that when adding tens to a two-digit number, the ones digit remains unchanged. By reinforcing this mathematical concept, the sheet aims to build proficiency in mental calculation speed and numerical fluency for learners, typically at the third-grade level. The clear layout and sequential numbering make it an effective tool for classroom assignments, home practice, or as supplementary math review material to strengthen fundamental addition skills.",{"@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/adding-tens-sheet-1-mental-addition-practice/637817/",{"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/adding-tens-sheet-1-mental-addition-practice/637817.png","ImageObject",300,407,{"name":92,"@type":93},"RuangKosong","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-22",true,{"@type":102,"interactionType":103,"userInteractionCount":81},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the core mathematical concept taught in this worksheet?","Question",{"text":112,"@type":113},"The worksheet focuses on mental addition of tens to two-digit numbers, specifically highlighting that the ones digit remains constant during this process.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How many practice problems are included in this document?",{"text":117,"@type":113},"There are 30 individual mental addition problems provided in the worksheet section.",{"name":119,"@type":110,"acceptedAnswer":120},"Is there a guide to check the accuracy of the problems?",{"text":121,"@type":113},"Yes, the document includes a dedicated 'Adding Tens Sheet 1 Answers' section that provides the correct solutions for all 30 problems.","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},637817,1792879188,{"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":81,"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":143,"read_time":24},962090883219,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","ADDING TENS SHEET 1  \n10 20 30 40 50 60 70 80 90 100  \n1) 35 + 10 =   16) 27 + 30 =   2) 52 + 10 =   17) 56 + 30 =   3) 67 + 10 =   18) 75 + 20 =   4) 58 + 10 =   19) 19 + 40 =   5) 75 + 20 =   20) 55 + 30 =   6) 66 + 20 =   21) 14 + 40 =   7) 51 + 20 =   22) 28 + 50 =   8) 38 + 20 =   23) 16 + 60 =   9) 25 + 30 =   24) 39 + 50 =   10) 42 + 30 =   25) 72 + 20 =   11) 37 + 20 =   26) 56 + 40 =   12) 68 + 10 =   27) 38 + 30 =   13) 39 + 30 =   28) 65 + 40 =   14) 45 + 20 =   29) 29 + 70 =    \n15) 56 + 30 =   30) 43 + 60 =    \nWhat happens to the ones digit when you add on tens with these numbers?  \nADDING TENS SHEET 1 ANSWERS  \n1) 35 + 10 = 45 16) 27 + 30 = 57  \n2) 52 + 10 = 62 17) 56 + 30 = 86  \n3) 67 + 10 = 77 18) 75 + 20 = 95  \n4) 58 + 10 = 68 19) 19 + 40 = 59  \n5) 75 + 20 = 95 20) 55 + 30 = 85  \n6) 66 + 20 = 86 21) 14 + 40 = 54  \n7) 51 + 20 = 71 22) 28 + 50 = 78  \n8) 38 + 20 = 58 23) 16 + 60 = 76  \n9) 25 + 30 = 55 24) 39 + 50 = 89  \n10) 42 + 30 = 72 25) 72 + 20 = 92  \n11) 37 + 20 = 57 26) 56 + 40 = 96  \n12) 68 + 10 = 78 27) 38 + 30 = 68  \n13) 39 + 30 = 69 28) 65 + 40 = 105  \n14) 45 + 20 = 65 29) 29 + 70 = 99  \n15) 56 + 30 = 86 30) 43 + 60 = 103  \nWhat happens to the ones digit when you add on tens with these numbers?
