Free interactive the solar system simulation. Explore the solar system hands-on online — great for whole-class or independent practice.

Type any function and see its shape straight away. Plot up to three at once in three colours to compare them, drag the trace point to read a value off a curve, and see where each one crosses zero.

Free interactive simple machines simulation. Explore simple machines hands-on online — great for whole-class or independent practice.

Free interactive the rock cycle simulation. Explore the rock cycle hands-on online — great for whole-class or independent practice.

Spin a spinner, flip a coin or roll a die and watch two sets of bars: the chances the shapes predict, and the results you actually got. Ten spins prove nothing; a few hundred and the two are hard to tell apart.

Move m and watch the line tilt; move b and watch it slide. Or drag the two points on the line and read the equation it writes back. A rise-over-run staircase climbs the line so slope becomes something you can count.
