Winter Progress Monitoring and Instructional Strategies for 4.NF.2
Student cannot compare fractions (=, <, >) using multiple strategies (compare to whole, compare to benchmark, compare numerators, compare denominators, etc) 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 >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
Ask students to compare fractions. They can use pictures/drawings, or strategies such as: compare to benchmark fractions, compare numerators, compare to whole number, compare denominators.
