But is this really the instruction you want to give to a child: Draw some dots in a suitable place? 'suitable' is quite a long/hard word and it would have to be very obvious where a 'suitable' place was on a piece of paper.
In other words, the whole instruction doesn't sound appropriate for kids to me.
It's a worksheet for 3.5 year old children where they need to use pencils to draw some dots in a specific place. They're not allowed to draw on the upper corner or lower corner, it has to be in the middle. So I am writing the heading as an instruction like "please draw some dots [in or on] a specific place." As suggested, [in] is appropriate, Packard? Thanks
