PARALLEL LINES MATCHINGMANIA is a cooperative learning activity in which students work together finding 2 angles given 2 or more parallel lines cut by a transversal.
There are numerous other activities similar to this one in my TPT store. These include:
Algebra I MatchingMania
Middle School MatchingMania
K3 MatchingMania, as well as numerous other K-12 activities!!
These activities can be used as an extension to your normal assignment or instead of your assignment.
