I always use a lot of games and activities in the class. Sets of Matching Cards are very versatile because there are so many ways of using the different types of cards.
They can be used for a whole class activity or a group/partner activity and a quick assessment for an individual student. Using cards as an assessment is a quick way to tell me if I need to reteach or review certain concepts or the class is good to go. I am always finding new ways to use them and the kids enjoy the variety.
