Vocabulary:

• equivalent fraction – two or more fractions that name the same amount

• simplest form – a fraction is in its simplest form if the numerator and denominator only have 1 as a common factor

• common denominator – a common multiple of two or more denominators 

• benchmark – a known size or amount that helps you understand a different size or amount  (ex. 1/2 is a good benchmark to compare 3/8 vs 7/12 -- 3/8 is less that 1/2; 7/12 is more than 1/2)

Extend understanding of fraction equivalence and ordering 

CC.4.NF.1  Explain why a fraction a/b is equivalent to a fraction (nxa)(nxb) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

Extend understanding of fraction equivalence and ordering

CC.4.NF.2  Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, <, and justify the conclusions, e.g., by using a visual fraction model.
