If you are looking for an evidence-based intervention targeted upper elementary, this course will give you just that - Fraction Face-Off! (FFO). FFO is a small-group Tier 2 intervention designed to promote fraction understanding for students with math difficulty. This intervention was previously identified by the What Works Clearinghouse (WWC, 2020) as an intervention that may increase student achievement in geometry and measurement, number and operations, and general mathematics achievement as outlined in this Fraction Face-Off! Intervention Brief.
