Acid and Bases naming card game.
Naming acids (especially) can be quite tricky! Play as many rounds of this game as you want with your students and make each round more challenging by adding a time limit or timing your students and having them beat their previous time.
Print and cut out the cards, give 1-2 cards to each student (depending on student number) and have them search for their partner. Half the cards have the formula, and the other half has the written name of the acid or base.
