How do I make a number bond?

Type the whole and its two parts into the prompt box (for example "10 as 6 and 4"), choose a style, and click Generate. Figviz draws a clean number bond with circles and connecting lines. You can refine the numbers, leave a part blank for practice, or switch styles and regenerate as many times as you like.

Is the number bond generator free?

Yes. Every Figviz account starts with free credits you can use right away, no credit card required. Buying a pay-as-you-go credit pack removes the watermark and unlocks 4K export resolution for crisp printing. Credits never expire.

Can I make number bonds to 10 and 20?

Yes. Just describe the whole you want, such as "number bond to 10 with parts 7 and 3" or "number bond to 20 with parts 12 and 8." Figviz draws the diagram with the correct arithmetic. You can also ask for a full set of bonds to ten or twenty across a worksheet.

Can I generate a blank number bond template?

Yes. Describe a blank layout, for example "a blank number bond with one empty whole circle and two empty part circles," and Figviz will generate an empty template you can print and fill in by hand. This is great for math centers, guided practice, and timed drills.

Can I print number bonds for my classroom?

Yes. Figviz exports number bonds at up to 4K resolution, sharp enough for worksheets, flashcards, or poster-size wall display. Download the PNG and print at home or school. For a standard handout, choose the portrait (3:4) or square (1:1) aspect ratio.

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

Enter the whole: type the total you want at the top of the bond, for example 10 or 20.

Add the parts: list the two parts that make the whole, such as 6 and 4, or leave one blank for a practice problem.

Pick a style: Classic keeps it clean black-and-white, Colorful color-codes the whole and parts, and Minimal uses thin lines for low-ink printing.

Choose an orientation: portrait (3:4) suits a worksheet, landscape (4:3) fits a projector, and square (1:1) exports cleanly for digital platforms.

Generate and refine: click Generate Number Bond, then adjust the numbers or layout and regenerate until it matches your lesson.

Download and print: export at 4K resolution for crisp handouts or wall display.

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.

Number bonds to 10 and to 20

Number bonds to 10: the classic set of pairs that make ten, such as 0 and 10, 1 and 9, 2 and 8, 3 and 7, 4 and 6, and 5 and 5. Memorizing these makes mental addition and subtraction within ten automatic.

Number bonds to 20: the next step, showing pairs that make twenty such as 11 and 9, 12 and 8, and 15 and 5. These build on bonds to ten and support bridging through ten.

Missing-part bonds: give the whole and one part, then leave the second part empty for students to solve. This turns a number bond into a quick addition or subtraction problem.

Three-part bonds: split a whole into three parts, for example 10 into 5, 3, and 2, to practice flexible decomposition and mental math.

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.

Frequently asked questions

A number bond is a math diagram that shows a whole number and the two parts that make it, drawn as a whole circle on top linked by lines to two part circles below. For example, 10 links to 6 and 4. Number bonds make the part-part-whole relationship visual and build early addition and subtraction sense.
