By remembering the "quarter minute conversions" of 0.00, 0.25, 0.50, and 0.75, I can quickly do the conversions in my head. If you can find a few are opposite.
I frequently choose to use the Degrees and Decimal Minutes format, even though the USGS maps I'm using are marked in Degrees, Minutes and Seconds. And what colour is used for different objects( like the river, railway, road bridge, culvert, tube well, open well, level crossing, temple, huts, church, tree, jungle, building, hedge, cultivated land, telegraph line, etc.) These symbols will need to be reinforced and revised through class activities where groups might be asked to find particular symbols on maps. internally in a floating point data type, and no additional work is required to print them as a floating point Line symbols: road, railway, boundary a river or canal.
