How to Structure Math Intervention When Your Roster is Constantly Changing

It is so common for Math Intervention rosters to feel like a revolving door. Whether you’re on a six-week cycle or a quarterly rotation, that constant shift can make it feel impossible to find your groove. When students are coming and going, the biggest hurdle isn't just the gaps in their math skills - it’s the gap in their sense of belonging.

If a student walks into your room in November and everyone else has been there since August, they already feel like an outsider in a subject that has likely made them feel like an outsider for years. To make Math Intervention work, you have to build a structure where community isn't a one-time "icebreaker" in August, but a sustainable system that welcomes every student on day one, whenever day one happens to be. To help you navigate this transition, here are two simple recommendations for building a community in an ever changing math intervention classroom.

#1: The "Welcome Home" Packet

When a new student joins your roster mid-year, their anxiety is at an all time high. They aren't just worried about the math, they’re worried about how their peers act in this class, how people respond to wrong answers, if they look confident, and so much more. To combat this, I recommend having a Welcome Packet ready to slide onto their desk the moment they walk in.

This shouldn't be a syllabus or a list of rules. Instead, start with a letter that says exactly what they need to hear: "I know you’ve struggled with math in the past, but I want this class to be different. This is a place where we take risks, where mistakes are part of the learning, and where you are going to see yourself grow."

The most important paper to have in this packet is a Mathography. This can be one paper with a simple prompt asking them what they find hardest about math and what a teacher has done in the past that actually helped. You must make your new intervention students feel seen the day they arrive in your class, and allowing them a way to share their “math baggage” is a great way to do that. 

#2: The "Non Negotiable" Five Minute Start

When you’re working with a short 30 minute block and a roster that feels like a revolving door, it’s tempting to skip the "fluff" and dive straight into the content. Don’t do it. When you have a classroom full of students who struggle, addressing the community and making sure everyone feels they belong is a biological prerequisite to learning math. I recommend setting a timer the second the bell rings and starting every class with one of my 6 Core Engagement Structures (like "Which One Doesn't Belong?" or "Same and Different").

Why this works for a changing roster:

• Low Floor Entry: These structures are designed so that a student who joined five minutes ago can participate just as easily as the student who has been there all year.

• The Safety of the Timer: When the timer goes off, you move on. This creates a predictable rhythm. The students who stay in your room will become experts at the routine and will naturally onboard the new students just by modeling how it's done.

• Shared Voice: It ensures that every student - no matter how new - hears their own voice in the room before the “hard” math begins.

  
  

If you only have 30 minutes, you might feel the urge to rush. But dedicating those 5 minutes to a shared, low stakes math conversation is the best investment you can make in your classroom culture. It tells your students that their thoughts and contributions matter more than just finishing a worksheet.

If you want to have all of these routines ready to go for every new student who walks through your door, grab a copy of my book, Teaching 6-12 Math Intervention, where I detail my favorite community building activities, all six core engagement structures, and so much more!
