This is a row of six discs on a spindle, held between two moulded end pieces that stand on their own feet. Each disc turns independently, and each carries digits or maths symbols around its faces. Spin them one at a time and a sum lines up along the top: a number, an operator, another number, an equals, an answer. Spin one disc again and the whole thing becomes a different question.

The symbols are the useful part. Along with the digits 0 to 9 the discs carry plus, minus, multiply, divide, equals, greater-than and less-than. That last pair is what makes this more than a counting toy — a child who can already add is suddenly being asked whether 4 is greater or less than 7, which is a different skill and the one most primary syllabuses rush past.

It is quiet, self-contained and small enough to live on a bedside table, so it tends to get picked up in odd minutes: while homework is being supervised, in a car, in a waiting room. Nothing falls off it, nothing gets lost under the sofa, and there are no loose pieces to count back in at the end.

The pastel discs are in blue, yellow, green, pink, lilac and orange, with the numerals printed large in white and dark red. A small arrow is moulded into one end cap. The frame stands unaided at whatever angle it is put down, which matters because a young child needs both hands free to turn a disc.

Be clear on what it is not. The carton reads ARITHMETIC CYLINDRICAL RUBIK'S CUBES, but this is not a Rubik's-brand puzzle and it is not a 3x3 twisty cube — there is no scramble to solve and no colour faces to match. It is a number cylinder that spins. It is also marked Ages 3+ with a choking-hazard warning for small parts, which we would rather print here than leave for the box to say alone.
