“LEDS PLAY BINGO!”
Divide the class into teams and provide each team with a bingo dauber and a set of element papers.
F. Developing Mastery
Have students on each team take turns using the bingo dauber to put dots around each element to show its LEDS.
The first team to correctly create the LEDS for all the elements wins.
