Number Bond to 10
A classic number bond with 10 as the whole on top linked to two part circles holding 6 and 4, building part-part-whole sense.
Number Bond to 20
A number bond with 20 as the whole linked to two part circles holding 12 and 8, extending bonds beyond ten.
Blank Number Bond Template
A blank number bond with one empty whole circle on top and two empty part circles below, ready to fill in by hand for practice.
Part-Part-Whole Number Bond
A number bond labeled with whole and part so students connect the diagram to the part-part-whole relationship.
Number Bond Worksheet
A practice worksheet with a row of number bonds where the whole is given and one part is missing for students to solve.
Three-Part Number Bond
An extended number bond where the whole is broken into three parts, useful for flexible decomposition practice.
What is a number bond?
A number bond is a simple math diagram that shows how a whole number breaks into two parts. It is drawn as a whole circle on top linked by two short lines to two part circles below, so 10 might link to 6 and 4. Number bonds make the part-part-whole relationship visual, helping students see that the same whole can be split many ways. A number bond generator turns a whole and its parts, or a target sum, into a clean printable diagram in seconds, with no drawing or design software needed.
How to make a number bond with Figviz
The part-part-whole concept
Part-part-whole is the big idea behind every number bond. Two smaller numbers (the parts) join to make a larger number (the whole), and the whole can be split back into those parts. Understanding this relationship is the foundation of addition and subtraction: if students know that 6 and 4 make 10, they also know that 10 minus 4 leaves 6. Number bonds train this flexible thinking early, so students stop counting on their fingers and start reasoning about how numbers compose and decompose. Labeling the top circle Whole and the bottom circles Part helps younger learners connect the picture to the language.

Can I get a blank number bond template?
Yes. To generate a blank number bond template, describe the structure you want: for example "a blank number bond with one empty whole circle and two empty part circles." Figviz will draw the circles and connecting lines with no numbers inside, ready to print and fill in by hand. Blank templates are perfect for guided practice, math centers, and timed drills, and you can print several copies so each student works through different number combinations during a lesson.
