Measure Mountain

Measure Mountain practises describing amounts and reading visual clues about size or time. Size Safari asks your child to compare pictures, order sizes, inspect balances or count blocks along an object. Its questions also include visible fill amounts. Clock Steps, for older players, asks for matching clock faces or taps to set the hands. Whole-hour times come before half-past rounds.

Where to start

For ages 2–4, start with Size Safari's bigger and smaller pictures; later levels offer length, fill amounts and balances. For ages 4–6, begin with Size Safari, then try Clock Steps. Its first level asks for one, three, six or nine o'clock; later levels include setting hands and half past.

Every game climbs from Seed, level 1, to Shine, and for older Kindergarten children the maths and reading games start higher. Good play climbs a level; a hard day holds it, and a level earned is never taken away.
