No, they need not.
a plane is any plane surface it usually have 3 or 4 points * * * * * You need only three points provided they are not collinear. And most planes have infinitely many points although there are geometries with only a finite number of points.
An infinite number in a Euclidean plane - which is the "normmal" plane. Some selected numbers in the finite or affine planes (but you need to be studying projective geometry to come across these).
Coordinate plane worksheets are needed for fourth grade and up because fourth grade is when you learn basic graphing and that is when you would need a coordinate plane worksheet.
