Ten Frame (Double)
Composing teen numbers as ten and some more. Subitizing and place value foundation.
Place value · Grade K–1 · 10 = 10, 14 = 10 + 4
For curriculum teams who need a production workflow. For developers who need an API.
Every diagram reviewed by a curriculum expert. Every receipt standards-documented.
Part-whole · Missing addend · Grade 1–2 · CGI: Join (Result Unknown)
Generating a diagram is easy. Generating the right one is the hard part.

Place value · Grade K–1 · 10 = 10, 14 = 10 + 4
Three groups of six modeled as equal partitions of an eighteen-unit whole.
Equal groups · Grade 3 · Multiplication structure
Locating three-fourths on a partitioned unit interval — fractions as numbers.
Fractions on a number line · Grade 3 · 3.NF.A.2
Twenty-three times fourteen decomposed by place value into four partial products.
Multi-digit multiplication · Grade 4–5 · Distributive property
Comparing forty-five with an unknown quantity, with a difference of seventeen.
Comparison · Grade 2–3 · Subtraction structure
Seven shown as five and two — anchoring early number sense to the ten frame.
Counting and composition · Grade K · Subitizing
Negative one positioned on a signed number line spanning negative three to positive three.
Integers · Grade 6 · 6.NS.C.6
Three-fifths shown as three of five equal parts of a single whole unit.
Fraction of a whole · Grade 3–5 · 5.NF.B.4
Every output is grounded in Illustrative Mathematics scope and sequence and the CZI Learning Commons knowledge graph.
The system knows which CGI problem types map to which representations, and which grade bands they’re appropriate for.
You describe the math; the engine decides the optimal visual. The API returns a ready-to-embed SVG.

}Returns a pedagogically correct, standards-aligned SVG. Every time.
Whether you’re building inside a curriculum platform, an authoring tool like Canva for education, or an LMS integration — the representation engine handles the hard part. Pedagogical accuracy, standards alignment, and grade-band appropriateness are decided for you, so your team can focus on the experience around the math.
Every diagram is deterministic, consistent across surfaces, and grounded in the same scope and sequence your editorial team already trusts.
