How do I make a tape diagram?

Describe your math scenario in the prompt box: state the whole, the parts, and any unknown value. Choose a style and click Generate. Figviz draws the rectangular bars divided into labeled segments with bracket annotations. Refine the prompt if any value or label needs adjusting.

Is the tape diagram generator free?

Yes. Every account starts with free credits you can use straight away. Buying a pay-as-you-go credit pack removes the watermark and unlocks higher resolutions. Credits never expire.

What is a tape diagram used for?

Tape diagrams are used to model addition, subtraction, multiplication, division, fractions, ratios, and word problems visually. They are especially common in elementary and middle school math because they make abstract number relationships concrete and support problem-solving strategies.

What is the difference between a tape diagram and a bar model?

They are the same thing with different names. "Tape diagram" is the term used in curricula like Eureka Math and Singapore Math. "Bar model" is used in many UK and Australian programs. Both refer to rectangular strip diagrams that show part-whole or comparison relationships between numbers.

Can I use tape diagrams for an elementary math class?

Yes. Tape diagrams are a core visual model in elementary math instruction, covering grades 1 through 6 topics such as addition, subtraction, fractions, and ratios.

What is a tape diagram generator?

A tape diagram generator is a tool that draws labeled rectangular bar models from a plain description of a math scenario. Tape diagrams, also called bar models or strip diagrams, break a problem into visible parts: each section of the rectangle represents a number or quantity, and brackets and labels show the relationships between parts and the whole. Figviz uses AI to turn a short description into a clean, print-ready tape diagram without any manual drawing or grid work.

How to make a tape diagram

Identify the whole and the parts in your problem (e.g. a total of 30 split into 18 and 12).

Decide how many bars you need: one bar for a single quantity, two bars for a comparison or ratio.

In the prompt box, describe the values, labels, and any unknown you want to highlight with a question mark.

Choose a style (classic, colorful, or minimal) and an aspect ratio that fits your worksheet or slide.

Generate and review the diagram. Adjust the prompt to change segment sizes, colors, or label wording.

What tape diagrams are used for

Addition and subtraction: show how two parts combine to form a whole, or how a whole splits into a known part and an unknown.

Ratios and proportions: place two bars side by side, divided into equal units, to make the relationship between quantities concrete.

Fractions: divide one bar into equal sections and shade a portion to show a fraction as a part of the whole.

Multiplication and division: draw equal groups as identical segments of a single bar to model repeated addition.

Word problems: translate complex written scenarios into a visual structure that reveals the missing value and the operation needed.

Comparing quantities: align two bars of different lengths to make differences and scale immediately visible.

Tips for a clear tape diagram

State every known value and mark the unknown with a question mark so the diagram communicates the problem at a glance. Keep the number of segments proportional to the values when possible, since mismatched sizes confuse readers. For ratio problems, use two separate bars with the same unit size so the scale comparison is honest. Add a bracket over the full bar whenever you want to label the total, and use a bracket below a segment to call out a part. If you are making a set of diagrams for a worksheet, keep the style consistent (classic or minimal) so the focus stays on the math.
