About these number bonds worksheets
Number bonds show how a whole splits into two parts, for example 10 is 6 and 4. Knowing bonds to 10 and 20 by heart makes mental addition and subtraction much faster. Each diagram has one empty circle: the whole or one of the parts.
The bonds-to-100 option uses multiples of ten (30 and 70).
Settings you can change
Each sheet has 12 questions by default (from 4 to 24), a name, date and score line, and an answer key on a separate page. Best for kindergarten to grade 2 (ages 5–8).
- Bonds to: 5, 10, 20, 100 (multiples of 10).
Teaching tips
- Learn bonds to 10 first; they unlock bonds to 100.
- Use fingers or counters to check.
- Write the matching addition and subtraction facts for each bond.
New questions every time
The questions are written by rules on your device, not picked from a fixed sheet, so every tap of “New worksheet” gives a different set. Nothing is uploaded. Explore all math worksheets.
Frequently asked questions
What are number bonds?
Pairs of numbers that make a given total. Bonds to 10 are 0+10, 1+9, 2+8 and so on.
What is the worksheet code?
Every sheet prints a short code. Typing the same code with the same settings rebuilds exactly the same questions, so you can reprint a sheet later or share the code with another teacher.
Does every worksheet come with an answer key?
Yes. The answers print on a separate page at the end of the PDF. Switch “Answer key” off if you only want the questions.
Which grades are these worksheets for?
Kindergarten to grade 2 (ages 5–8), depending on the settings you choose. Switch on “Big print” for younger children.
Can I make a different number bonds worksheet for each student?
