Multiage Math Block: Four Structural Routes

A concept map for planning how to structure the ALN Balanced Math Block (Launch → Main Lesson → Closure → Menu) in a multiage or blended classroom. Routes range from fully integrated to fully separate.

← More Integrated More Separate →
Route 1 Route 2 Route 3 Route 4
Route 1 · Most Integrated

Together Always — Differentiate in Menu

"One lesson, one community, differentiation lives in Menu."
Block Structure
Launch
5–10 min
All grades together — shared number sense routine, multiple access points
Main Lesson
20–30 min
All grades together — one shared task; upper grade extends within the same problem
Closure
5–10 min
All grades together — student-led synthesis of shared task
Menu
30–35 min
Differentiated by grade/readiness; upper grade pull-outs clustered strategically (e.g., later in unit when routines are solid)
Strengths
  • Strongest community of learners
  • Lowest planning load
  • All students hear each other's thinking
  • Easiest to manage solo
Considerations
  • Requires tasks with wide entry points
  • Upper grade extensions must be genuinely rigorous
  • Pull-out timing needs intentional planning
Best For

Units where grade-level content overlaps significantly (e.g., volume, fractions, place value) and when you're building classroom culture early in the year.

Route 2 · Mostly Integrated

Together Always — Occasional Split Main Lesson

"Mostly one community; split when the math genuinely diverges."
Block Structure
Launch
5–10 min
All grades together — always
Main Lesson
20–30 min
Most days: shared task together
Some days (~2–3×/unit): Grade A and Grade B work on different tasks simultaneously
Closure
5–10 min
Reconvene — each group shares what they worked on; cross-grade connections named
Menu
30–35 min
Differentiated; small-group pull-outs as needed; upper grade extensions available
Strengths
  • Flexibility when content diverges
  • Community stays mostly intact
  • Closure reconnects grades meaningfully
  • Manageable planning increase
Considerations
  • Split days require two tasks ready
  • Logistics of simultaneous groups
  • Risk of split becoming the default
Best For

Units with mostly shared content but a few concepts that are grade-specific (e.g., a unit where Grade A and Grade B share fraction reasoning but diverge on operations).

Route 3 · Mostly Separate

Together for Launch — Almost Always Split Main Lesson

"Shared community at the start; grade-specific work most days."
Block Structure
Launch
5–10 min
All grades together — always; shared number sense routine anchors the community
Main Lesson
20–30 min
Almost always split: Grade A works on Grade A task  |  Grade B works on Grade B task  |  Rare shared days when content genuinely overlaps
Closure
5–10 min
Reconvene — brief whole-group reflection; teacher names connections across grade-level work
Menu
30–35 min
Grade-differentiated menus; teacher pulls small groups from either grade as needed
Strengths
  • Grade-level content fidelity
  • Launch preserves community daily
  • Clear HLC alignment per grade
  • Works well with a co-teacher or aide
Considerations
  • Higher planning load (two lessons/day)
  • Students miss cross-grade discourse
  • Requires strong independent work habits
  • Community-building needs intentional attention
Best For

Units where grade-level standards diverge significantly, or when accountability pressures require clear grade-level task documentation. Also works well mid-year when students have strong menu independence.

Route 4 · Fully Separate

Parallel Blocks — Grades Taught Independently

"Two classrooms in one room — maximum grade-level fidelity."
Block Structure
Launch
5–10 min
Grade A and Grade B have separate launches — different number sense routines aligned to each grade's HLC focus
Main Lesson
20–30 min
Fully separate — teacher works with one grade while the other works independently or with a co-teacher; then switches
Closure
5–10 min
Separate closures — each grade reflects on their own task; no cross-grade synthesis
Menu
30–35 min
Fully separate menus; teacher pulls small groups from one grade at a time; co-teacher supports the other
Strengths
  • Maximum grade-level content fidelity
  • Easiest to align to pacing guides
  • Clear for accountability/reporting
Considerations
  • Loses the power of multiage community
  • Highest planning and management load
  • Requires co-teacher or strong independence
  • Misses cross-grade mathematical connections
  • Students don't benefit from hearing varied strategies
Best For

High-stakes testing periods, units with zero content overlap, or as a temporary structure when a new teacher is building confidence. Not recommended as a default — the multiage setting's greatest asset is the community it creates.

💡

The ALN Principle Across All Routes: Launch is always an invitation to engage with substantive mathematics — multiple access points, student discourse, public recording of thinking. No matter which route you choose, Launch is the daily anchor that builds and sustains your multiage community. The further right you move on the spectrum, the more intentional you need to be about preserving that community.

How Do I Choose a Route?

Ask these questions when planning a unit or a week of instruction.

Does the content overlap significantly across grades?
R1R2 Yes → lean toward Routes 1 or 2 and use shared tasks with grade-level extensions built in.
Are grade-level standards mostly divergent this unit?
R3R4 Yes → Routes 3 or 4 give you grade-level fidelity while Launch keeps community alive (R3) or fully separate (R4).
How strong is student independence during Menu?
R1 Early in year → Route 1 while building routines. R3R4 Mid/late year → Routes 3–4 become more viable.
Do I have a co-teacher or instructional aide?
R3R4 Yes → Routes 3 and 4 become much more manageable. Solo teacher → Routes 1 and 2 are more sustainable.
Is community-building a priority right now?
R1R2 Yes → Routes 1 and 2. The more students work together, the more they learn from each other's strategies and models.
Do I need maximum grade-level documentation?
R4 Yes → Route 4 gives you the clearest grade-level record, but consider the trade-offs for student learning and teacher workload.
