Teaching 4.NF.A.2 – Compare Two Fractions with Different Numerators and Different Denominators

 

comparing fractionsNumber & Operations – Fractions – 4th Grade

Extend understanding of fraction equivalence and ordering.

CCSS.Math.Content.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.

Teacher Notes

I know how to use fraction models to show equivalent fractions.
I know how to create equivalent fractions.
I know the larger the denominator, the smaller the partitions of the whole.
I know comparisons of fractions are only valid if the whole is the same size.
I can use a variety of strategies to compare fractions.
I can record the result of the comparison using symbols >, =, or <, and justify my conclusions.
