4th grade math sub plans that survive contact with reality

Fourth grade math is heavy machinery: multi-digit multiplication, long division, fraction equivalence. It is also the year students figure out that a substitute does not know the class rules, which means a vague plan does not get gently ignored, it gets stress-tested. If the work is confusing, a 4th grade room will find every crack in it by 9:30.

So a week of 4th grade math sub plans has to be more than a stack of worksheets. It needs a script, familiar work, and a paper trail. Here is how I build that week, and what the substitute actually does with it hour by hour.

Why review is the only thing that works

The tempting move is to leave the current unit, so the class "does not lose a day." I have watched that fail too many times to count. A substitute explaining partial products for the first time is not instruction, it is improv, and the kids who were already shaky come back shakier.

A review day is not a lost day. Multi-digit computation and fraction reasoning are exactly the skills that decay without reps. A week of well-chosen review often does more for a 4th grade class than a week of wobbly new content, and it does it without you in the building.

The five days of the 4th grade week

Each day has the same four-page rhythm: a warm up anyone can start alone, two main pages, and an early finisher for the student who is done in eleven minutes and looking for entertainment.

Day 1: place value and mixed review

Rounding large numbers and comparing values: confidence work. The goal of day one is a calm room, so the sub can learn the class while the class does math it owns.

Day 2: multiplication and division

The core 4th grade muscle. Multi-digit multiplication and division practice in the same formats students have seen all year, so the only question the sub gets is "do we show our work?" (The note says yes.)

Day 3: fractions

Equivalence and comparison at review level. Fractions are where a substitute would be most tempted to teach, so this day is built to make that unnecessary: familiar models, familiar formats.

Day 4: word problems

Multi-step problems using the week's operations. The substitute note gives the one instruction that matters: stuck students skip, circle, and move on, and the teacher will handle it Monday.

Day 5: mixed review

Everything mixed together. The Friday pages double as your Monday diagnostic: flip through them when you return and you can see in five minutes which skills need a touch-up.

Behind these five sits a spare sixth day, and each day includes a morning work page so the pre-math stretch of the morning is covered too. If the copier dies or the file never reaches the sub, an If You Cannot Print page scripts twenty minutes of whiteboard math from nothing.

The 4th grade packet and its companions

Everything above ships as one 37-page file: student pages, substitute note, roster, report form, backup activity, and labeled answer keys. The three-grade bundle is there for departmentalized teams; the weekly homework packet extends the same independent-review routine across the whole year.

What to leave besides the math

The packet handles the math block, but a smooth sub day is mostly logistics. Keep these in the same folder:

• A seating chart with pronunciation notes for the tricky names.
• Your two most reliable students, named, as the sub's helpers.
• The schedule with the times that actually happen, not the official ones.
• Dismissal notes: who rides which bus, who gets picked up, who walks.
• The name of the teacher next door who can answer questions.

I keep the full list in my one-page checklist, linked below. For the whole system in one read, start with the math sub plans guide, and the 3rd grade and 5th grade weeks cover the rooms on either side of yours.
