I Have, Who Has: Polyatomic Ions is an excellent activity to help chemistry students practice converting between the names and formulas of common polyatomic ions!
-Set-up and game instructions
-Reference table with all the polyatomic ion names and formulas included in the game
-30 I Have, Who Has cards that can be cut out (and laminated - optional)
**To facilitate printing, all game materials are included in two versions: with background and without background.
This game includes opportunities for scaffolding, and can be used by students of various levels to reinforce their knowledge of common polyatomic ion names and formulas. For students who are just being introduced to polyatomic ions, the game can be used as a familiarization activity or anticipatory set, and can be completed with the help of the included reference table. For students who have already become familiar with polyatomic ions, the game can be used as a collaborative active practice or review game, and can be completed with limited access to reference materials.
-Distribute the game cards to the students (remember: all cards must be distributed in order for the game to work).
-Select one student to start the game.
-The starting student will read the bottom half of their card, asking who has the polyatomic ion with the given name. (For example: “Who has… Sulfate?”)
-All of the other students will check their own cards to see if they have the formula for that polyatomic ion on the top half of their card. (In this example, SO42-)
-The student who has the formula for that polyatomic ion will then read the top half of their card (In this example: “I have SO42-.”) They will then continue by reading the bottom half of their card with the name of the next polyatomic ion. (For example: “Who has… Permanganate?”)
-Steps 4 and 5 will be repeated until all of the cards have been read. The “I Have, Who Has” cards are looped in such a way that the game should end with the starting student reading the top half of their card.
