This Fraction Set is perfect for Common Core State Standards for 4th grade fractions. It includes notes for introducing fractions, activities and games for centers which help students practice creating equivalent fractions, reducing fractions, and comparing fractions. Word problems help students develop their understanding of mixed numbers, and Puzzled Penguin pages require students to justify their explanations! There are also several hands-on activities which can be done whole group or in intervention groups with fewer students. Activities created by Jaclyn Seiders, NBCT.
