Number Bonds 11 15 Practice Activities
Printable math drills that help children build addition fact fluency by finding number bond pairs for totals 11 through 15.
Practice that builds confidence
What children learn
These number bonds 11–15 worksheets help children practise breaking totals into two parts and putting the parts back together as addition facts. Learners work with totals just beyond 10, building confidence with pairs such as 6 + 5 = 11, 8 + 4 = 12, and 9 + 6 = 15.
The printable activities include part-part-whole bond diagrams, missing-part questions, and related addition facts for the totals 11, 12, 13, 14, and 15. They fit naturally within Math > Math Drills > Addition Facts practice for children who are strengthening quick recall and flexible thinking.
Number bonds show that one whole number can be made from two smaller parts. In this collection, the whole is always 11, 12, 13, 14, or 15, so children practise facts such as 7 and 4 make 11, 10 and 3 make 13, and 8 and 7 make 15. The focus is not only getting an answer, but seeing how addition facts are connected.
How the practice progresses
Children may begin by completing a visible bond diagram, then move to finding a missing part when one part and the whole are given. The same relationship can also appear as an equation, for example 9 + __ = 14. This progression helps children connect pictures, numbers, and addition sentences instead of treating each format as a separate task.
A simple parent routine
At home, choose one target whole, such as 12. Say, “I have 5. What part do I need to make 12?” Let your child answer, then ask them to say the full fact aloud: “5 and 7 make 12.” Use small objects, fingers, or quick drawings if needed, then complete a short worksheet section to record the facts. Rotate the target number over several sessions so 11–15 stay familiar.
Classroom uses
Teachers can use these pages for math centers, morning review, small-group intervention, or independent addition fact practice. A useful routine is to assign one total to a table group and have students list all possible pairs before completing the printable. The worksheets also work well after a mini-lesson on part-part-whole thinking or as a check for students who rely too heavily on counting one by one.
Common errors to watch for
Some children reverse the role of the whole and a part, especially in bond diagrams. Others find one correct pair but do not notice the related turnaround fact, such as 6 + 8 and 8 + 6. Watch for totals that are one too many or one too few, a sign that the child is counting quickly but not checking the final total.

Answers and answer key support
After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The pages give focused practice on just five totals, so children can notice patterns instead of feeling overwhelmed by all addition facts at once. A child-friendly strategy is “start with the bigger part, count on, then check the whole.” For example, for 8 + __ = 13, start at 8, count up to 13, and record the missing part as 5.
Helpful answers
Frequently asked questions
What are number bonds for 11–15?
They are pairs of numbers that combine to make the totals 11, 12, 13, 14, or 15, such as 6 and 5 for 11 or 9 and 6 for 15.
How do these worksheets support addition fact fluency?
Children repeatedly see the same totals in bond diagrams, missing-part problems, and equations, which helps them remember facts and understand how the parts relate to the whole.
Should children use objects with these printables?
Yes, if they are still developing the facts. Counters, buttons, or quick drawings can help children check that two parts really make the whole before they write the answer.
What mistake is common with number bonds above 10?
Children often count one too far or stop one short when finding the missing part. Encourage them to count on carefully and then reread the full fact.
Can these worksheets be used in math centers?
Yes. They are well suited for independent centers, partner checks, or small-group review focused on addition facts with totals from 11 through 15.
