Handouts Session 240 Hillen, Olanoff, & Welder, Moving beyond common denominators handout.pdf


The common denominator approach can be used to compare any two fractions, but it is not always the most efficient strategy. Participants will develop alternative strategies for comparing fractions that draw upon number sense and reasoning, consider instances in which each strategy would be useful, and discuss how these strategies align to CCSSM.
