How to differentiate one lesson for mixed ability class on Mac: a teacher's routine
You can differentiate one lesson for a mixed ability class without writing three lessons. Keep one learning goal and one closing check. Change the support, the reading load or the challenge for each group instead. This page covers the time you have, why the work piles up, fixes you can use for free, and where Lazur helps on your Mac.
The short answer
- Keep one learning goal for the whole class and change only the route to it.
- Public school teachers get about 53 minutes of planning time a day, so keep the extra work small and fixed.
- Build the tiers in one shared document, then use a closing check to move students next time.
- Lazur can explain a passage, draft a simpler version and guide you through making copies. You check every line.
What planning one lesson for mixed ability levels costs you
Planning minutes you do not have
The average daily planning time is about 53 minutes, and that time also covers grading, email and other tasks. If you spend part of it on three versions of one lesson, something else slips. Often the thing that slips is the feedback students were waiting for.
Grading that multiplies
Every version produces its own work. If you grade the same question three ways, your evening grows fast. Use one rubric and one closing check across all tiers, so the core skill gets graded the same way for everyone.
Students who notice the labels
Students notice group labels quickly. A visible easy group can make some students stop trying, and a visible hard group can make others feel stuck. Use neutral names, and let students move between tiers without a public announcement.
Groups that stop matching students
Without regular review, a group can stop matching the student in it. Students grow at different speeds, so a tier that fit in September may not fit in November. Check the closing ticket each week, so moves feel routine.
Planning that stays in your head
Plans kept in your head disappear when you change grade levels or schools. Keep the master file in one shared folder, and next year's version takes less time to build.
A number you still have to measure
The sources behind this page do not give a figure for how many hours a week differentiation takes. Track your own time for a few weeks. That gives you a real number for your room, which is more useful than a national average.
Why it happens
Planning time is short and uneven
NCTQ found that its large district sample averages 51 minutes of planning a day. About 45 districts, roughly one third of the sample, allocate about four hours a week. Eleven percent of the sampled districts do not mention planning time at all. Less time means less room for new tiers.
Ready made materials assume one level
Many handouts and worksheets are written for one reading level. The gap shows up on the first page, and you end up rewriting the same text by hand. That work is slow, and it is hard to do well at the end of a long day.
Tools assign to a class, not a group
Teams Assignments can target individual students, but only within one class at a time. Google Classroom's help page does not document group steps. When a tool cannot target a group in one step, you repeat the same steps for each class and each student.
A wide spread in one room
Students arrive at different points for many reasons, including earlier schooling, language, reading practice and missed lessons. You see the spread in the first week. A single lesson still has to reach all of it.
Fairness gets mistaken for sameness
Some teachers feel the fair move is to give everyone the same task. That feels equal, but it can leave some students far from the goal and others bored. The Aftab study found that stakeholders wanted differentiation, while teachers lacked the time to do it.
The evidence is mixed on how much it helps
Research summaries on differentiated instruction disagree on how much it helps. The sources checked for this page do not settle the question. Treat every fix below as a small test in your own room, and keep what works.
How to fix it
These work with or without any app.
Keep one goal for the whole class
Write the learning goal in one sentence that every student can reach. Do not mention ability levels in it. Tiers change the route to the goal, so the exit check can stay the same for everyone. This one habit keeps the extra planning small.
Change one thing per tier
Pick one element and change only that. Reading length is a good first choice. Sentence starters, a short glossary, pictures or a shorter passage are other options. A challenge tier can add a second source or a harder question. Keep the rest of the lesson identical so the copies stay easy to compare.
Build tiers in one document
Put the base lesson in one file, then make a copy for each tier. In Google Docs, go to File > Make a copy. In Pages, start from a custom template so the layout matches every time. In Finder, select a file and press ⌘D to duplicate it. Name each file with its tier, not a student name.
Sort by work, not by label
Use the last exit ticket to set the tier. Move students when their work shows they are ready for a different route. Tell the class that moves happen, so a change feels normal and does not single anyone out.
Use a closing check that sorts
End the lesson with one question that shows the skill you want. Each answer falls into a tier: missing evidence, partial evidence, or evidence plus a reason. Skim these in a few minutes, then plan the next day from them.
Draft simpler text with Lazur, then check it
Hold ⌥ ⌘ over a passage and ask Lazur to explain it in plain words. Then ask for a shorter version with the same facts. Lazur drafts and types the text where your cursor sits. Check every fact, name and date yourself before a student sees it. A Walton Family Foundation and Gallup article reports that teachers who regularly use AI tools estimate they save 5.9 hours a week. That is a teacher estimate, not a measured result.
Swap tiers with a colleague
Ask a colleague who teaches the same unit to read your tier copies. A second reader finds the sentence that is still too hard. You keep the final say on what goes out to students.
Put planning in a fixed slot
Choose one planning block each week and keep it on your calendar. A small, same-day slot tends to get used. A vague plan to do it later often does not. Use the first block to build one set of tiers, not the whole unit.
Keep a master file and log changes
Keep one master file for each unit in a shared folder. Add a short note under each lesson about what you changed and why. Next year, you start from your notes, not from memory.
Use school templates and rules first
If your school has a lesson template or a document standard, use it for the layout and place the tiers inside it. Check your school's policy before you put any student work into an AI tool.
What a mixed ability class really means
A mixed ability class is one room with a wide spread of reading, writing or math skills. Some students read the passage easily. Others need the words read aloud, or the steps broken into smaller pieces. You do not need labels to plan for this. Start with the work students handed in last week, and look at where it breaks down.
How much planning time you actually have
Public school teachers get about 53 minutes of planning time a day, according to NCES data reported by the National Council on Teacher Quality. That is just under 4.5 hours a week. The figure covers all planning, not only differentiation. Planning time also varies by district. NCTQ reports that Fresno Unified gives secondary teachers eight hours a week and elementary teachers four.

Six Weeks a Year: How AI Gives Teachers Time Back (Walton Family Foundation)Differentiation competes with everything else in that time. A 2015 study by Aftab surveyed 120 middle school teachers in Pakistan. The teachers were short of planning and instructional time for differentiated lessons. All stakeholders in the study still wanted teachers to use differentiated strategies. The study is small and comes from one country, so use it as a clue, not a verdict. It fits the problem in one sentence: the wish is there, and the minutes are not.
A worked example: one lesson, three levels of support
Say you teach a science lesson on the water cycle. The goal stays the same for every student. Students explain evaporation, condensation and precipitation, and they point to one sentence from the text that backs up each stage. Only the route changes from group to group.
Group one gets the passage with pictures, bolded key terms and sentence starters such as Water evaporates when. Group two gets the standard passage and answers three questions in full sentences. Group three gets the same passage plus a short comparison with a second source. All three groups finish with the same exit ticket: one sentence that names a stage and gives evidence.
- Write the goal in one sentence that does not mention ability levels.
- Name the one thing that changes, such as reading length or support.
- Keep the closing check identical for every group.
- Write the support into the task itself, not on a separate sheet.
- Check that every group still has to think, not only copy.
The exit ticket does the sorting. You can skim those tickets in a few minutes, then move students between tiers the next day. Without that check, you are guessing which tier fits.
Mistakes that make this harder
- Writing three full lessons. You triple the grading, and the versions drift apart by Thursday.
- Lowering the content for the lower group. Change the route, not the destination.
- Labeling groups where students can see them. Use neutral names like Group A.
- Fixing groups all year. Mixed ability work changes as students learn.
- Planning for the class you wish you had. Use last week's real work as the baseline.
- Skipping the closing check. Without it, you guess which tier fits each student.
Most of these mistakes come from trying to be fair by doing more. Changing the route is less work than writing three lessons, because the core plan lives in one place.
Student data and AI tools
Lazur listens and looks at the screen only while you hold the shortcut. Audio and the screenshot go to AI providers to answer, and they are not stored. Content is never used to train AI models. Those facts help, but they do not replace your school's rules. A safer habit is to write the passage without names, then add names yourself in your gradebook.
Tools that help or get in the way
Microsoft Teams Assignments can send work to specific students. Open the student dropdown under Assign to, pick names or search for them, then select Assign. Microsoft's support page says you can only assign to individual students in one class at a time. If you teach the same lesson to two sections, you repeat the steps in each class.
Pages 15.4 starts every document from a template, and you can create and manage custom templates. Build your tiered handout once as a custom template, then reuse it for each unit. Pages can duplicate pages or sections inside one document. In Finder, select a whole file and press ⌘D to duplicate it.
Google Docs runs in the browser on any Mac. Use File > Make a copy to make one file per group, and name each copy with its tier. Google Classroom's help center describes classes, assignments and grades, but its help page does not document steps for groups. Check the current help before you plan around a group feature. For the Docs side of this routine, read Google Docs for teachers on Mac.
| Tool | What helps | Limit to plan for |
|---|---|---|
| Microsoft Teams Assignments | Assign to specific students with the Assign to dropdown | Individual students in one class at a time |
| Pages 15.4 on Mac | Templates, custom templates, duplicate pages or sections | Duplication of sections only inside one document |
| Google Docs in the browser | File > Make a copy for each tier | Each copy is a separate file you must track |
| Google Classroom | Classes, assignments and grades online | No group steps on the help page checked |
What to do next
Pick one lesson for next week. Choose a unit you already teach, so the content is familiar. Write the goal, the one changing element and the closing check. Build the tiers in one document. Leave the other lessons alone until that one works.
If some students have IEPs, the tiers can help, but the goals and accommodations come from the plan itself. Read the routine for drafting IEP goals faster before you write tiers for those students.
One well built lesson gives you a template for the next one. That is the whole point of this routine.

Handles the small stuff
A plan you can start this week
- Day 1
Pick one goal and one change
Write the goal in one sentence without ability words. Name the one element that changes between tiers, such as reading length or sentence starters. Pick a unit you already teach, so the content is familiar.
- Day 2
Build the base and the tiers
Write the base lesson in one Google Docs file or Pages template. Use File > Make a copy in Google Docs to make each tier. Keep the closing check word for word the same across all tiers.
- Day 3
Check the text
Read each tier aloud, or ask Lazur to explain the passage out loud. Check facts, names and dates by hand. Remove any student details you pasted in for drafting.
- Day 4
Teach and collect exit tickets
Run the lesson with the right tier in each group. Collect the closing checks. Skim them and mark who needs a move, and who is ready for a challenge.
- Day 5
Move students and save the master
Move students where the tickets show a need. Update the master file and add one note on what to change next week. Keep the note short, so you actually read it at the next planning block.
Questions people ask
Do I need three separate lessons for a mixed ability class?
No. Keep one lesson and change the route, the support or the length of the task for each group. Three full lessons multiply your planning and your grading.
How long does it take to plan one differentiated lesson?
The sources checked for this page do not give a figure for that. Planning time overall averages about 53 minutes a day for every task. Time one differentiated lesson for a few weeks to get your own number.
Is it fair to give some students easier work?
Fairness is about the goal. Keep the goal the same for everyone and change the support so each student can reach it. A lower goal for a specific student is a different decision, and it belongs in a plan that follows your school's process.
How many tiers should I make?
Start with two. Add a third only after the first two work for a while. Each extra tier means another copy to build and another set of answers to grade.
Can Lazur help me write the tiers?
In part. Lazur drafts and types text, and it explains a passage out loud. It does not know your students, and it does not click buttons in your apps. You check every line before a student sees it.
Does Lazur work on Windows?
Lazur runs on macOS, on both Apple silicon and Intel Macs. Windows is planned, not available.
Is student data safe if I use AI tools for this?
Lazur sends audio and the screenshot to AI providers to answer them, and they are not stored. Content is never used to train AI models. Your school's rules still come first, so do not share student records unless your school allows it.
Should I buy a ready made differentiated curriculum instead?
You can. This page covers the free route. Ready made curricula cost money, so check the price and the terms before you buy one.
