Lesson Plan

Compare two fractions with different numerators and different denominators by creating common denominators, then comparing the numerators

Compare two fractions by creating common numerators, recognizing that when numerators are equal, the fraction with the smaller denominator is larger (because the pieces are bigger)

Compare two fractions by reasoning about benchmark fractions -- especially 1/2, but also 0 and 1 -- to determine which fraction is greater without finding a common denominator

Explain why fraction comparisons are valid only when both fractions refer to the same whole, and identify situations where different-sized wholes make a comparison invalid

Record the result of a fraction comparison using the symbols >, =, or <, and justify the conclusion using a visual fraction model (area model or number line)

4.NF.A.2

4.NF.A.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 >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
