Help the dock show a number in tens and ones. Every green bundle has 10 countable parcels. Every amber parcel is one.

Take your time. This is practice, not a test.

Count from 1 to 10. One bundle and ten loose parcels show the same quantity.

About Place Value Harbour

Complete eight fixed tens-and-ones manifests, then build 64 in a separate bounded transfer dock with visible bundles and individual ones.

Suggested age
Ages 6–7

Read, build and partition two-digit numbers as tens and ones
Pace
Untimed
Controls
Keyboard, Touch
Reading
Short prompts, number words and labelled choices; an adult may read the prompts aloud.
Instruction help
A voluntary ten-parcel practice dock, a three-step visual hint ladder, labelled bays, visible unit marks, finite mini retry docks and separate Target/Current equations are available. Spoken instructions are not included.

How to play

Complete eight fixed manifests using the requested Exchange or Split and short explanations. Then use Add/Remove controls in Transfer Dock to build 64 as 6 tens and 4 ones.

Adult help

Read a prompt aloud if useful. Point to each of the ten marks in one bundle, then count loose parcels. In the separate Transfer Dock, let the child choose add/remove actions rather than building 64 for them. Completion includes an optional off-screen 37-object discussion prompt.

Accessibility

The optional number word route is visible text, not recorded speech. Some children may benefit from an adult reading the short prompts. Accessibility-user review remains open.

Detailed access information
Keyboard
Use Tab with Enter or Space for every control. After a correct check, focus moves to Next; after Next, it moves to the new prompt. The native pause dialog restores focus to Pause.
Touch
All actions are labelled touch controls of at least 44 CSS pixels; no dragging is required.
Screen reader
The current bays, equations, prompts, feedback and quantity changes are text-labelled and announced. Manual screen-reader review remains open.
Timing
Untimed. There are no scores, lives, streaks or automatic exchanges. Correct feedback remains until Next is chosen.
Motion
No motion is needed for play. Reduced-motion preferences remove the small harbour transitions.
Sound
No sound or audio prompt is supplied or required.
