Sometimes (often) elementary math books present difficulties in formatting. I would probably braille the counting numbers first, followed by the spatial addition problem, then the poem and linear problem, in the order shown in print. However, there is no absolutely right way to do this kind of stuff. Keep in mind that there is probably some purpose to the order in which the information is presented to the reader and the transcriber should try to maintain that order. Consistency in the formatting of the braille version is important.
