Standard(s):
[MA2019] (3) 15 : 15. Explain equivalence and compare fractions by reasoning about their size using visual fraction models and number lines.
a. Express whole numbers as fractions and recognize fractions that are equivalent to whole numbers.
b. Compare two fractions with the same numerator or with the same denominator by reasoning about their size (recognizing that fractions must refer to the same whole for the comparison to be valid). Record comparisons using < , >, or = and justify conclusions.
[MA2019] (4) 14 : 14. Compare two fractions with different numerators and different denominators using concrete models, benchmarks (0, ½, 1), common denominators, and/or common numerators, recording the comparisons with symbols >, =, or <, and justifying the conclusions.
a. Explain that comparison of two fractions is valid only when the two fractions refer to the same whole.
