MODULE 2 Arithmec Operaons Including Division of Fracons
Topic A: Dividing Fracons by Fracons Lesson 4: Interpreng and Compung Division of
a Fracon by a Fracon—More Models Student Outcomes § Students use visual models such as fracon bars and area models to divide fracons by fracons with different denominators.
§ Students make connecons between visual models and mulplicaon of fracons.
