## Unit 6 - Fraction Models and Order

## Essential Question

How can I find equivalent fractions and how are equivalent fractions helpful when comparing fractions?

Vocabulary

Benchmark Fraction - Common fractions you can use to compare or make sense of other fractions; 1/4, 1/3, 1/2, 2/3, 1/4 (among others) are all common benchmark fractions..

Common Denominator - Two or more fractions have common denominators if the denominators (number of equal parts an item is divided into) are the same..

Common Numerator - Two or more fractions have common numerators if the numerators (number of parts you have/number of parts selected) are the same..

Equivalent Fraction - Two or more fractions are equivalent if they are equal; fractions can be equivalent even if the numerators and denominators are not the same; equivalent fractions can be found by multiplying or dividing the numerator and denominator by the same number.

## Learning Goals

- I can create equivalent fractions by dividing shaded regions into greater or fewer parts.
- I can explain why two fractions are equivalent using visual fraction models.
- I can record the results or comparisons with symbols >, =, or < and justify my answer with fraction models.
