Course: Elementary Education Assessment 5006
Subject: Mathematics And Science 5008
Chapter: Fractions Operations With Fractions And Ratios 1
Fractions and proportional reasoning mark a major shift from additive thinking to multiplicative thinking. Praxis 5008 expects you to understand how students construct fraction meaning, why equal partitioning is required, how equivalence is justified, how comparisons are reasoned (not guessed), and why fraction algorithms work. It also expects you to connect fractions to ratios, unit rates, proportions, and percents as one coherent system of reasoning about relationships.
