While I’m not a fan of making students memorize anything on the periodic table, the more familiar they are with it the easier it is for them to use. Do I expect them to know the atomic number of carbon is 6? No, but it’s helpful if they know the general location of carbon so it’s easy to look up.
Playing periodic table bingo is a fun way to review the elements. I was recently at Dollar Tree and found this bingo cage with 60 balls, cards, and chips for a buck! The balls are numbered on one side, but I grabbed a sharpie and wrote the atomic symbols on the back (for general science you can usually stop at 36 on the periodic table). Break off the balls, place them in the cage, and get ready to have some fun!
Students are given a bingo card
that has the names of 24 elements. As you give the cage a spin and remove a ball, you call out the chemical symbol. Students then cover the matching name on their bingo card. (For example, you call out “Na” and students cover sodium). I allow them to have their periodic table out for reference- remember I don’t expect them to memorize, just become more familiar with the table.
Can’t find the bingo cage at your local dollar store? They are also available to purchase on Amazon (affiliate link), or you can buy ping pong balls instead (which are a little easier to pick up) and pull them out of a plastic tub.
