About Hundred Chart Builder
Hundred Chart Builder turns the classic hundred chart into a hands-on construction task at a friendly robot factory. A band of the chart appears with some numbers missing, and the child places the correct numbers from a small palette to complete the grid. Selecting a blank cell and then a number — or a number and then a cell — snaps it into place when correct and gently rejects it when not, so the child reasons about what comes next, what came before, and how the tens and ones line up. The number of blanks grows with each level, and the chart band moves around so children meet numbers across the whole hundred. Working with the hundred chart builds the place-value foundations that underpin addition, subtraction, and skip counting, and it makes patterns in our number system visible and tactile. The game runs in any modern browser, needs no sign-up, and shows no advertising to children. Progress is saved only on the device and appears in the Parent Dashboard. It pairs well with our hundred chart and place-value worksheets for offline reinforcement.

A hand for grown-ups
- Before you start
- Find a calm few minutes with no rush. Let your child know it is fine to find some of it tricky — that is what practice is for.
- While they work
- Sit nearby but let them lead. If they get stuck, ask "what could you try?" rather than giving the answer — the thinking is the point.
- Afterwards
- Ask them to show you one they found easy and one they found hard. Praise the effort on the hard one, not just the right answers.
- Watch out for
- Rushing. If answers come too fast and wrong, slow the pace down together rather than pushing for more.
- Away from the screen
- Look for the same maths in everyday life — counting stairs, sharing snacks, spotting shapes on a walk.
