Suggestions for teachers to help them teach this lesson
This lesson is intended to address the cluster level expectations for 4.NF.A, including, “ordering…fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100."
Unlock features to optimize your prep time, plan engaging lessons, and monitor student progress.
Tasks designed to teach criteria for success of the lesson, and guidance to help draw out student understanding
Would you rather have $${{4\over9}}$$, $${{2\over3}}$$, $${{5\over7}}$$, or $${{3\over4}}$$ of your favorite pie? Show or explain your reasoning.
Play the following game with a partner using a set of Fraction Cards. The goal is to compare the two fractions appearing on each card, determining if they are equivalent and, if not, which is larger. The rules for the game are as follows:
