Nudge the point in 0.52 one place right and it becomes 5.2 — ten times as big; nudge again and it becomes 52. Nudge left and the number shrinks to one tenth. The place-value table shows both sides of the story: either the point travels between the digits, or the digits slide across the places — two views of one rule.
0.52 → 5.2 → 52 — what actually moved? Drag the slider to shift the decimal point, and compare two views on the place-value table: the point moves while digits stay (place names follow), or the digits slide while the point stays fixed. Both tell the same rule. Get a random starting number and master ×10 and ÷10.
