Who builds PrintNum?
PrintNum is built by a small independent team of parents, former K-6 teachers, and software engineers. We work with classroom educators to validate every worksheet layout against real curriculum use cases.
About PrintNum
PrintNum is a free, ad-free math worksheet generator built by a small team of parents, classroom teachers, and software engineers. We make it fast for educators to create printable math block characters, ten-frame cards, 100 charts, and array models — all exportable as PDF and PNG.
Our mission
Visual math manipulatives help young children turn abstract numbers into something they can see, touch, and arrange. We believe every teacher and parent — regardless of budget — should be able to generate high-quality, curriculum-aligned math worksheets in seconds. PrintNum removes the cost and prep time barrier so more children get the visual foundation they need for arithmetic fluency.
