This Fraction Progression checklist follows the common Core Fraction Standard progression from 1st through 5th grade standards. It can be used for a guide for lesson implementation or as an individualized checklist to monitor and differentiate instruction for students. You can use this checklist as a guide for your fraction instruction. This checklist is based on the progression laid out by ReThink Mathematics. Using this checklist you can see gaps in understanding, a data driven guide for baseline data on where to start instruction, or to track individual progress in fraction understanding.
