Diagram order

The following is the first page of a lab exercise. At the bottom are numbered figures that are used to help with grouping. (Though the directions say this is to be cut out, the students' teacher has let me know the student I am transcribing this for will probably not be cutting them apart to group them and perhaps will just be listing his answers.) My question is, if you can see the numbered order of these 20 figures, they more or less are going vertically up and down. Would you retain the same approximate layout as shown in print, or would you change the presentation to an itemized horizontal layout, with a TN stating the changes? (I was thinking of horizontal, perhaps having them placed across two facing pages). Thank you in advance for any guidance.
