Big Idea:
The Common Core defines understanding of fractions as a 3rd grade Critical Area, beginning with unit fractions. It's time to grow our understanding.

Big Idea:
Students need to connect fractions to their world, and use them to help be more accurate in measurements. This lesson begins to make that connection.

Big Idea:
Whole objects and sets of objects are not the only things that can be divided into fractional parts. Knowing how number lines can be partitioned is important to the application of fractions to everyday tasks.

Big Idea:
Students must acquire an ability to explain their thinking using accurate vocabulary words. Journal entries are a perfect venue for this learning.

Big Idea:
Naming unit fractions is a start, but helping students visualize how they can be grouped together to make a larger part of a whole is the focus of today's lesson.

Big Idea:
Using large number lines provides an opportunity to use a large strip of paper to represent the whole amount and conceptualize how fractional amounts changed based on the size of the whole amount.

Big Idea:
After a large unit like fractions, it is important to assess the students ability to apply and communicate their knowledge. These two very different activities will help you assess and record your student's learning according to the Common Core Standards.
