Common questions

Is this aligned with what they learn at school?
+
Yes — every face is built around the core skills covered in U.S. Grades 1–3, including the Common Core math standards for addition, subtraction, multiplication, division, geometry, and measurement.
What age is it actually best for?
+
The sweet spot is 6–9, but advanced 5-year-olds and review-loving 10-year-olds love it too. The grammar and times-tables faces grow with them.
Will my kid get bored after a week?
+
It has more content than it looks like — full times tables 1–12, eight parts of speech with examples, a working clock, and shape geometry. Most kids return to it over months as different subjects come up in school.
Is it durable?
+
It's built from premium thick paperboard with reinforced edges. Survives drops, snack hands, and being shoved into backpacks. Not waterproof though — keep it away from juice boxes.
Do you ship internationally?
+
U.S. shipping is free over $35. We ship to Canada, the UK, and EU at checkout — rates and timing shown before you pay.

One cube.
A whole grade of wonder.

Give your child a learning tool that earns its place on the desk — and stays there long after the novelty wears off.
