Fractions with unlike denominators – a lesson plan

Vicki graciously allowed me to teach our 5th graders again today.  Kerry and Marsha gave their time to observe and offer me feedback.

Learning Progression 

Level 4:
I can show what I know in numbers and pictures.

Level 3:  
I can use equivalent fractions to add and subtract fractions.

Level 2:
I can use visual models to add and subtract fractions.

Level 1:
I can decompose fractions into the sum or difference of two fractions.

We used the Navigator to collect responses from all learners prior to going over each task.

Think of the questions and the peer-to-peer discussions.  There are as many students answering 4/8 as 14/15.  Can you describe the thinking that might yield an answer of 4/8?
