Describe how the size of the fractional part is related to the number of equal sized pieces in the whole.
Remarks
For instance, "As the number of equal parts increases, the size of each fractional part decreases."
Fractions can also be compared by looking at numerators, such as when comparing 1/5 and 1/6. Since both fractions represent one part of a whole, the size of the parts can be compared. Fifths are larger than sixths so 1/5 is greater than 1/6.

Description |
| "What's the part? What's the whole?" | This lesson provides a conceptual approach to multiplying a fraction times a whole number and a whole number times a fraction. Students are to use an understanding of the meaning of the denominator and numerator to figure out a strategy for finding the solution. |
| Fractions Meet Pattern Blocks | Students will identify the fractional parts of a whole using pattern blocks. There is a focus on unit fractions. |
| Fraction Counting Book | Students will make a book of fractions by counting by a specified denominator. They will represent the fractions as pictures, in number form, word form, and on a number line. |
