Videos, examples, solutions, and lessons to help Grade 3 students learn to understand a fraction 1/*b* as the quantity formed by 1 part when a whole is partitioned into *b* equal parts; understand a fraction *a*/*b* as the quantity formed by *a* parts of size 1/*b*.

Common Core: 3.NF.1

### Suggested Learning Target

**Understanding fraction 1/b as part of a whole partitioned into b equal parts**

In this lesson you will learn that fractions are equal size parts of a whole by looking at fair and unfair situations.
**Understand any fraction (a/b) as "a" (numerator) being the numbers of parts and "b" (denominator) as the total number of equal parts in the whole**

**Understanding Fractions**

As the number of equal pieces in the whole increases the size of the fractional pieces decreases.

The denominator represents the number of equal parts.

The numerator of a fraction is the count of the number of equal parts.**Fair sharing**

Fair sharing means equal sharing. In word problems it means fractions.

Examples:

1. Six children share four brownies equally so that each child receives a fair share. What portion of each brownie will each child receive? 2. What fraction of the rectangle is shaded? How might you draw the rectangle in another way but with the same fraction shaded?**3.NF.A.1**

This lesson will help teachers and parents to understand and explain fractions.**Partitioning Shapes Using Models: 3.NF.1**

How to express a shaded amount as a fraction?

Also learn about partitioned shapes using models with more than one whole.
