Alexander Arrangement of Elements Forever Periodic Table
Randomized to Organized Lesson
for student determination of the most logical arrangement
Student interaction is a vital part of this lesson.
Engineering an arrangement of elements with a hands-on activity has proven to enhance learning and subsequent understanding at the beginning of chemistry - not to mention the creative fun of successfully getting a grip (so to speak) on the periodic table.

Students in different grades and/or at different intellectual levels should vary in speed of discovery of the helix, but the capabilities of the non-academic oriented (especially boys) may be surprisingly stimulated by the hands-on aspect to what has traditionally been typically abstract.
The teacher may decide to insert this activity following the first of the three PowerPoints, leading up to a similar creative step by duh shank coor twah (phonetics for de Chancourtois).
The 3D Alexander Arrangement Forever periodic table may be introduced as the most recent product derived from the same kind of work the students have performed - logic intact, and with Mendeleev's line and vertical groups of elements intact as well.
Tiered Learning, as well as the general level of a class, will help you select the best jumbled element cards from the four below.
