Ohio outline map with every county
Ross County is the largest by land; Ashtabula looks bigger on the map because its part of Lake Erie is drawn with it. Lake County is the smallest. Its neighbors, Pennsylvania, West Virginia, Kentucky, Indiana and Michigan, are drawn around it without numbers.
The four groups of the quiz, north-west, north-east, central and south-west, and south-east, make four worksheets from one map.
