These Math Conversions Manila Envelope Matching Games make for great math center activities! Students can work alone or in groups to match the letters on the envelopes (one unit, i.e. one week) with the number cards (it's equivalent unit, i.e. 7 days). After students match up all of the cards they can turn them over to reveal a pattern. If their pattern matches that of the answer key, they know they got them all correct!
