As students reach higher levels of math, incoming skill gaps can be particularly challenging since they have compounded over so many years. It can often be difficult to figure out where to begin when the dual tasks of closing skill gaps and teaching new material are on the to-do list.

Our goal is to help you determine where to begin the often immense task of review and gap filling. This article includes common skill gaps that we recommend reviewing with Algebra 1, Geometry and Algebra 2 students. The recommended skills shared come out of data collected from Knowre Math’s Ready? Check. Go! diagnostic. This diagnostic is designed to identify skills gaps by giving students a chance to engage with key topics from their prior math course (ie. Algebra 1 students complete a Ready! Check. Go! focused on 8th grade/Pre-Algebra skills).

Below you’ll find a list of recommended skills to review with students. Please note that the percentage indicated at the end of each skill reflects the percentage of students who demonstrated an understanding of that skill of focus.
