Randomized to Organized Lesson

Equipment to cut data boxes apart and clear tape will be required.

Boxes will be cut apart by students and assembled in most obvious order (which we expect will be oxidation number) and taped together.
Then, using the secondary set of information in the databoxes, the result of the primary sequence must be assembled with the new relationship without altering the first.

Jumbled Seventeen Element Data Boxes Without Atomic Numbers
If you can't drag this image to a graphics app - like Photoshop - click on it to go to the image alone and try there, any size that you like. If nothing works, email me to send you the graphic.
Students faced with figuring the correct (and most obvious) order of these element boxes have only two references in each box - tougher than when the atomic numbers are included.
The boxes for Argon and Potassium, where the oxidation numbers are reversed from the proper order (becoming evident in the secondary connection), plus the following element, Calcium, are not included, removing the necessity for discussing pair reversals at this time.
