PRINTING INSTRUCTIONS: 
The pages of the activity booklets have been rearranged so that when the A4 pages are printed they should be able to be folded in half to create an A5 booklet with the pages in the right order.
For this to work they must be printed double-sided/duplex, with page flip on the short edge. 
Also ensure page setup is set to borderless (printed edge to edge right to the borders of the page). You may have to go into advanced printer preferences / print using system dialog to amend these settings.
