comparing fractions

Part of our curriculum is to teach our students how to compare fractions.  We focus a great deal on equipping students with strategies for doing this mentally.  They take part in an investigation where they 'discover' these mental strategies.  Though many students dislike the initially struggle, they realize that developing these mental strategies saves them time in the end.  If they just stop and THINK they can often discover which fraction is larger without ever even thinking about 'common denominators.' 

One reality is that sometimes the use of equivalent fractions is necessary and we ask the kids to use common denominators as a last resort. 

This foldable was created with the students AFTER the investigation and BEFORE the weekly quiz.  It was intended to be a summary reference piece.  I created it with the intention of it being used as a FLOWCHART.  If you look closely, students are asked to try one of the mental strategies at the top and then it is suggested that they move to the bottom of the foldable flowchart if one of the mental strategies did not apply.
