Differentiating Math Without Writing Five Lesson Plans
Every differentiation workshop ends with the same instruction and the same arithmetic problem. Meet students where they are. You have 26 of them, four prep periods a week, and one of you.
Here's what the workshop tends to skip. Differentiation is not five lesson plans. It's one lesson with one variable deliberately changed. Pick the right variable and it's a planning decision that takes ten minutes, not a second job.
Why "five lesson plans" is the wrong target
Differentiating a math lesson means adjusting one thing while the lesson stays whole: either the task everyone works on, or who practices what. Teachers who end up building five versions of everything are usually varying both at once, which multiplies the prep without improving the match.
The labor complaint is legitimate, by the way. It isn't a sign anyone is doing it wrong. A model of differentiation that requires parallel curricula for one classroom was never going to survive contact with a Tuesday, and the answer is a narrower method, not more hours.
It also helps to name what differentiation isn't. It isn't giving some students less math. Students who stay in grade-level work while getting support for the specific thing they're missing tend to outpace students moved back to redo earlier content (TNTP), which is convenient, because supplying one prerequisite is far less work than running a second curriculum.
So which variable are you changing: the task, or the practice?
Two moves cover most of what a mixed-readiness class needs, and they have different triggers. Either you keep one task and build range into it, or you keep one objective and vary who practices what.
Branch 1: one task, multiple entry points
Use this when your class shares the concept but spreads out on fluency and confidence. The design goal is a task with "a low floor and high ceiling" and "high cognitive demand with multiple solution strategies" (Edutopia): easy enough that every student can start, rich enough that nobody finishes it in four minutes.
In practice that usually means one context and several sizes of the same question. Offer the problem at a few difficulty levels, mild, medium and spicy, and let students choose (Edutopia). A 2nd-grade class can all work the same "how many ways can you make 12" task, with some students using two addends and others using three. A 5th-grade class can all compare fractions in the same context, with the numbers doing the differentiating rather than the worksheet.
Two things make this branch work. The first is one prepared extension question instead of a second assignment, so your quick finishers go deeper on the same math rather than further ahead into next week's. The second is grouping: on open tasks there's a real case for mixed pairs, because "variation in student abilities within a group" produces "greater richness of ideas," and pairing randomly helps "disrupt any narrative that only certain kinds of learners are capable of engaging in deep mathematics" (Edutopia).
Branch 2: one objective, different practice
Use this when a handful of students are missing something specific, which is a different problem from a class that ranges. Everyone keeps the same objective. You change who spends their minutes on what.
The move is short and targeted: pull four or five students for eight minutes of explicit teaching on the missing prerequisite while the rest work the grade-level task. Systematic instruction of exactly that kind, modeling the thinking, guided practice, corrective feedback, is one of six recommendations the What Works Clearinghouse rates as Strong Evidence for elementary math, and it's the ingredient nothing else substitutes for.
The rule that keeps this branch honest is that the group is temporary. "Grouping decisions are best made in the moment" (Edutopia), which means today's group forms around what you saw yesterday and dissolves when the need is met. Same-students-every-week is a different practice with a different effect, and it's worth being strict with yourself about the difference.
How do you tell which branch you're in?
- The spread is in how far students can push the thinking. Branch 1. Raise the ceiling; don't split the class.
- A few students are missing one identifiable prerequisite. Branch 2. Pull them briefly, teach the thing, send them back into the grade-level task.
- Both, on different days of the same week. Normal. Most units need each at some point.
- You seem to need five versions. The task is probably too narrow rather than the class too varied. A single-answer procedure forces you to write a version per level; a task with room absorbs most of the range on its own.
Where a practice tool does the repetitive half
Both branches leave a residue: the volume of practice that has to land at different levels for different students, which you'd otherwise assign one student at a time. That's the half software is genuinely good at, and the half that eats prep periods. It's the slot Boddle fills. Either way you like to work, you're covered: turn on adaptive practice and each student gets problems at their own level, or assign the standard yourself and control exactly who practices what. The learning-gaps report is often what tells you which branch the week needs, because "four students are missing unit fractions" calls for a different plan than "everyone needs a higher ceiling." Wrong answers cost nothing, so a student working a gentler version isn't docked for being there, and read-aloud covers both the question and the answer choices, so a reading gap doesn't quietly get recorded as a math gap. It's free for teachers and students, with every character earnable without paying, so who gets differentiated practice never depends on which families upgraded.
The limit deserves saying plainly, because this is where the category oversells. Software differentiates practice. It does not differentiate the lesson. It won't run your open task, facilitate the discourse, or do the eight minutes of explicit teaching that carries the strongest evidence in the research, and it shouldn't be the thing that decides which students are "low." Teachers in a 2021 LEANLAB study put the boundary about right: "Boddle provides rigorous instruction that I can add to their math instruction as a supplement." Supplement is the correct word.
Frequently asked questions
How do I differentiate math without making five different assignments? Change one variable instead of all of them. Either keep a single task and build range into it, using one context with several sizes of the same question plus one prepared extension, or keep a single objective and vary who practices what, pulling a short small group for the students missing a specific prerequisite. Both are one plan with a deliberate variation rather than five plans. The five-version feeling usually signals a task too narrow to hold a range, not a class too varied to teach.
Should I group students by ability in math? Briefly and by skill, yes. Permanently, no. A group that forms because four students need help with equivalent fractions and dissolves once they have it is a needs-based teaching move; "Grouping decisions are best made in the moment" (Edutopia). A standing low group is something else, and students read it accurately. For open tasks, mixed or random pairs have a case of their own, since "variation in student abilities within a group" produces "greater richness of ideas" (Edutopia).

Differentiation gets sold as a volume problem and it's really a design problem. One task with a high ceiling, or one objective with a short pulled group, covers most of what a mixed class needs, and neither requires a second curriculum. Then let the practice around it carry the repetitive part: work students will actually do, at the level each of them is really on, free for every student in the room, with you deciding what it's for.
