This is a blank Periodic Table that is used to make the blank Periodic Table posters for the 3 games in My Store CHEM by Gloria. The boxes are more square than a traditional periodic table and the element cards fit the boxes on this table. I took a flash drive, with this pdf file of the blank periodic table, to a office/printing store and had it printed on thick paper approximately 24"x 40". I then had the posters laminated and they are in very good condition after several years of heavy use. I highly recommend using this poster because its bigger than a 8.5" x 11" periodic table and the students actively learn how to navigate the Periodic Table. The students place the element cards in the correct period and family. It is worth the money spent on printing and laminating. I do many hands on activities and this is one of the most effective lessons the students do in the beginning of the school year.
