# Fractions / Fractions and Unit Squares

Activity 3 of 15
This lesson uses a dynamic geoboard to extend the concept of fraction to unit squares, where the unit fraction (1/b) is a portion of the area of a unit square.

## Planning and Resources

Objectives
Students understand that a fraction (1/b) is one part of a unit square that has been partitioned into b equal regions.  The fraction (a/b)  is a copies of (1/b)  on both a number line and in a unit square.

Vocabulary
tiling

## Lesson Snapshot

#### Understanding

This lesson helps to illustrate the need to clearly specify the unit of a fraction in order for it to be interpreted or used with any meaning.

### What to look for

Some of the wording in the problems might need to be adjusted slightly depending on the background of the students. The language of tiling is one possible instance—a region is tiled by a shape if it is completely covered by the shape with no gaps or overlaps.

### Sample Assessment

Identify three fractions equivalent to (4/12).
