HIGH LEVERAGE CONCEPTS EXPLAINER VIDEOS

High Leverage Concepts (HLCs) are one of ALN's trademark resources. These are key understandings identified at each grade level across Pre-K through Grade 8. They help focus math instruction and intervention by identifying the big ideas at each grade level that will support success in the next grade. We have also identified how these concepts typically unfold across a school year in our HLC Learning Progressions.

We have created explainer videos for each grade level band to help educators visualize the mathematics, models, and strategies in each HLC progression. Check out the PreK - Kindergarten video below! You can access the videos for Grades 1-5 by completing the form below.
