Online math practice, at your pace.

A K–8 math app. Fresh questions. Helpful hints.

Mistakes are OK
Just your level
How it works

Every question is sharpened for one child.

Fresh practice for the skill your child is exploring, with help when they need it and room to try again.

01

Written for one child

Each exercise focuses on the skill your child is on right now.

02

Help that steps back

A picture appears while an idea is new and fades as it isn't needed. Neither hint gives the answer away.

03

Progress you can trust

Secure means unaided correct answers across separate days. A streak is not evidence.

A session

Whetta sits beside them, not above them.

It says hello, nudges when asked, and smiles when an idea lands. It never reacts to speed — nothing is timed.

A ribbon is 3/4 of a metre long. You cut it into pieces that are 1/8 of a metre each. How many pieces do you get?

A nudge
Whetta only speaks when it's asked
Mistakes welcome

The eraser is part of the pencil.

Getting it wrong is how the next question gets written. Nothing is timed and nothing is ranked — a wrong answer only tells Whetta what to show next.

When it's hard, Whetta says “tricky one” — curious, never disappointed.
Two hints when they want them. Neither gives the answer away.
Stop whenever you like. There's no streak to lose.
For parents

See how sharp each skill really is.

Every skill moves through four stages. Secure means unaided correct answers across separate days — a streak is not evidence.

Whetta has one job: your child's next step, in whatever they're learning. Nothing is timed, nothing is ranked, there's no advertising, and your family's data is never sold.
