Fraction Harbor

Getting the harbor ready…

How to play

Choose from five open harbor chapters, 30 authored tasks, repeat orders and a separate free workshop. Every cloth piece uses the same whole sail.

  1. Choose a suggested path or any level on the harbor map.
  2. Select a cloth piece, then a sail. You can also drag, return pieces or Undo.
  3. Where cutting is available, preview two or three equal pieces before confirming. Read each level’s cloth and cut conditions.
  4. Fill all sails and meet the visible conditions, then choose Set sail. The boat shows your actual patchwork.

What you can practice

Parts of a whole, equivalent fractions, composing missing amounts and planning shared materials. These are game activities, not an ability assessment.

Choosing a starting point

Little Makers suggests visual exploration for ages 5–6; Sail Builders suggests ages 7–8; Harbor Planners starts with advanced tasks for ages 9–12. Every chapter stays open.
