There is nothing like Periodic Table Battleship to get them practicing the periodic table🙂
Update! When I do this I split the class into pairs and give them the set up. I would start off having them call out element names or atomic numbers, then I would have them use the period/group number to call out the elements. To challenge the students at a higher level I have them call out atomic masses or electronegativity. To mark the “ships” I had them draw on the periodic table (its laminated) but next time I will use bingo chips. Hope that helps!
