Each new school year students enter into the classroom with gaps in their prior knowledge. The challenge of how to address those gaps, while simultaneously introducing students to new grade-level standards, is a difficult balancing act.

Many Knowre Math students start the new year off by taking Knowre’s Ready? Check. Go! (RCG) diagnostic. The RCG was created to identify incoming skills gaps by giving students a chance to show what they know on key topics from the previous year (ie. 7th graders take a Ready! Check. Go! focused on 6th grade math skills).

For the second year in a row the data from the Ready? Check. Go! found that students in second, third, and fourth grade demonstrated a much higher level of math readiness for the new school year and many fewer gaps than their counterparts in grades 5 through Algebra 2.

Now that we are well into October, the need to stay on pace and cover grade level content is front and center. When opportunities for review do arise, however, we’ve put together a list of recommended skills to focus on. The specific skills are included on the list below because they were the ones that the largest number of students struggled with.

Click on your curriculum of interest to jump directly to that section. The percentage you'll see indicated at the end of each skill reflects the percentage of students who demonstrated an understanding of that skill of focus.

Algebra 1

Geometry/Algebra 2

*Please note, we are not including any skills from grades 2 and 3 because there were no skills in those grade levels that less than 80% of students struggled with.
