Slide a ruler onto the map, read the cm, then use the scale (1 cm = 5 km or 1 : 50 000) to find the real distance.
Map Scale Ruler is free, interactive map scale practice. Kids slide an on-screen ruler along a road so its 0 sits on the start town, read the distance in centimetres (including half-cm ticks), then use the map scale to find the real distance: bar scales like 1 cm = 5 km, and ratio scales like 1 : 100 000 (1 cm = 1 km) or 1 : 50 000 (1 cm = 500 m), with the conversion from cm to m to km shown step by step. In Plan mode they work backward, turning a real distance into map centimetres and sliding the town to that tick, and two-leg trips add two measured legs before converting. Best for Grades 4–7.
