Ten Partners
About This Worksheet
Ten Partners is a kindergarten number-bond activity that helps children find the missing part needed to make a whole of 10. Each problem shows 10 at the top of a number bond and gives one part below, such as 1, 7, 4, 5, 8, or 2. Children think about what number must go in the empty box so the two parts make 10. For example, if one part is 7, the missing partner is 3 because 7 and 3 make 10. This helps children understand 10 as a whole that can be broken into different pairs.
Curriculum and Grade Alignment
This worksheet is made for kindergarten learners who are beginning to work with number bonds and combinations of 10. The main goal is to help children find a missing part when the whole is always 10. Before using this page, your child should be able to count to 10 and combine small groups with some support. The next step is writing addition equations that match the number bonds and recalling common partners of 10 more quickly. This activity supports early addition and part-part-whole thinking by showing how two smaller numbers join to make one larger amount.
Student Tasks
On this worksheet, students will complete six number bonds. They will look at the given part, think about how many more are needed to reach 10, and write that number in the empty box. The starting values include several different numbers so children see that 10 can be split in many ways. Each problem uses the same whole, which keeps the focus on learning the partner relationships. This builds missing-number reasoning, addition readiness, and number sense.
Common Challenges and Misconceptions
Some children may add the given number to 10 instead of finding the missing part. Others may count past 10 because they are not yet comfortable stopping at the whole. A child may also think the two parts must be the same size. Encourage your child to say, “I have this many. How many more do I need to get to 10?” Using fingers or counters can make the missing partner easier to see.
Implementation Guidance
Teachers can use this worksheet after introducing number bonds with counters or connecting cubes. It works well in a small group because students can build 10 physically before recording the missing part. Parents can place 10 small objects on a table, cover some of them, and ask how many are hidden. Then connect that idea to the number bond on the page. This makes the missing-part relationship much more concrete.
Details and Features
This worksheet includes six number bonds with 10 shown as the whole in every problem. One part is provided and one part is left blank. The large boxes and simple branch lines keep the number-bond structure easy to understand. The repeated whole of 10 gives children focused practice with several different partners. The printable supports number bonds, missing parts, addition readiness, and early fact fluency.
