Slide the decimal point along the digits — every place it moves ticks the power of ten — to zoom standard numbers into c × 10ⁿ and back, then span the zoom ruler from an atom to the Sun to read how many powers of ten apart they are.
The number sits on a digit strip inside the scope and the player drags the decimal point: each place it moves is one factor of ten, so the exponent dial ticks with it and the scientific-notation readout rewrites itself live. Zoom-in rounds stop where exactly one nonzero digit sits before the point (later levels cover the dial so the player counts the shifts and sets the exponent), zoom-out rounds slide the point n places to rebuild the standard number, and compare rounds stretch an arrow across a log zoom ruler between two real lengths — a red blood cell, Everest, the Sun — to read the power of ten between them. It targets the classic errors of 34.5 × 10⁷, the wrong exponent sign for small numbers, and confusing 10⁶ with six zeros. Best for Grades 7–8.
