Number Bonds to 10 Worksheets
Classic number bond diagrams: the whole in the top circle, two parts below it, one of the three left empty. Sometimes the whole is missing (add the parts), sometimes a part (subtract), mixed on the same page so the student has to look before writing. Wholes go up to 10 here; the medium setting goes to 20 and hard to 100.

FAQ
Which circle is blank?
It varies problem by problem: the whole about a third of the time, either part the rest. That mix is what makes number bonds teach both addition and subtraction at once.
Do the downloads include answer keys?
Yes, every PDF ends with a key page that repeats the layout with the answers in green. Turn the Answer key switch off for a problems-only file.
Can I get different versions for each student?
Turn on the 5 versions switch before downloading. You get five different sheets in one PDF, each with its own answer key, so neighbouring desks cannot copy.
How is the whole marked?
The top circle has a blue outline, so even a child who cannot read the layout knows which number is the total.
Can kids do these on a tablet?
Yes. Practice online puts a pen tool over the same sheet, so answers (or clock hands) can be drawn with a finger or stylus and wiped for another try.
