Mathematics and Science Institute for Students with Special Needs (The Meadows Center)


The following MSTAR Equivalent Fraction Intervention lessons target struggling Tier 2 students. The intervention lessons provide a concrete structure to help students learn the foundational skills necessary for success in increasingly complex mathematics curricula. 

The intervention lessons do not have a recommended time limit, as students may move at varying paces, depending on prior experience with the content. We estimate that each intervention lesson will take at least 30 minutes and that some lessons will need to be divided up over several days.

Each intervention lesson contains several aspects of research-based intervention strategies and lesson design. Additional activities are included for students who need further practice.
