About this worksheet
Making 10 Matching drills number partners for 10 across three formats, serving the Common Core standards K.OA.1 through K.OA.4. Students first draw lines between number cards, matching 9 to 1, 4 to 6, 7 to 3, 2 to 8, and 5 to 5, with printed dot rows beside each numeral for counting support. Four fill-in sentences follow, such as 6 + __ = 10 and 8 + __ = 10. The sheet closes with two circle-the-partner questions, offering 2, 3, and 5 as candidates for 7, then 8, 7, and 6 as candidates for 2. An answer key covers all eleven items.
