PLEASE... Response to Intervention Math Our school is struggling with math interventions to implement before referring students for testing. Does your school have a plan or a curriculum that you are using? For reading we are using the three tiers, 1 is guided reading at individual reading levels in a small group and literacy centers. 2 is intense one on one Reading recovery in first grade or small literacy groups with Reading specialist.Tier 3 is referral for special education. We are using Everyday Mathematics as our curriculum. Anyone??
