This is a 3 lesson unit intended as an introduction to fractions. The activities use a linear model to help students understand the fraction concepts. There is a continuous story about the teacher wrapping birthday presents and having ribbon left over. Students will use cut out paper strips to represent the ribbon to discover the understandings noted in the standards. This unit was developed by Becky Pittard and the Volusia County Lesson Study Group using a Lesson Plan template (included) chosen by the AFT Common Core cadre for lesson sharing. Aligned to CCSS: 3.NF.1 , 3.NF.2

Thank you so much for this resource. I appreciate that is so carefully written. It takes the students from a physical situation to finally plotting the fractions on a number line.
