1 - Put the Arrow piece, the one with the Magnet Axis Directions, on the bottom.
2 - Put the first Square piece, the other pieces, with the square holes, aligned and on top of that. Glue the two, on the outside.
3 - Using 4 Magnets as place holders, stack the other 3 Pieces, and glue the lot on the outside.
4 - After finding the North of each Magnet (a Compass South poit points to it) mark it with a Permantent Ink Felt Marker.
5 - Put the Magnets carefully, the arrows point to the North, put them, first 4 spaced 3 places apart, glue the top, then 4 to the right of those, glue again, then the remaining 4 glue again.
That's it! :)
