Teacher planner · See what’s ahead

Plan your teaching.
Not your paperwork.

Classroom Radar keeps your curriculum, units, lessons, classes, assessments, tasks and notes in one planner that knows your real rotating timetable. Plan the next lesson — or the whole week — in conversation with Radar, and turn any lesson into a printed activity sheet.

One connected system

Your planning already connects. Your tools should too.

A lesson belongs to a unit. A unit answers to curriculum. The marking, the photocopying and the note you wrote after fourth period all belong to the same day of teaching. Classroom Radar keeps those relationships instead of asking you to remember them.

CurriculumThe objectives this class covers this year
UnitGuiding questions, topics, and its lessons in order
LessonOn the date the class meets, with its outline and materials
Activity sheetBuilt from the lesson’s objectives, edited by you, printed as Student and Teacher versions

And around the plan

Tasks, projects and notes attach to the lesson, unit or class they are about — and stay reachable from the planner rather than a separate app.

From a planned lesson to a worksheet in your hand

The Activity Builder is part of the planner, not a separate tool: it starts from the lesson you already planned and ends at the printer.

  1. 1 · Plan lessons and unitsObjectives, source material and the class come from the plan you already made.
  2. 2 · Create activitiesChoose from eleven activity types or a practice test; Radar generates and checks every item against your objectives.
  3. 3 · Edit and printChange any question, regenerate one, set the style and paper size, and print the pages you see.
  4. 4 · Student and Teacher versionsStudents get the sheet without answers; you get the answer key, from the same document.

Plan a lesson, a week or a unit by talking it through

Say “Help me plan the next Science 8 lesson” — out loud or typed. Radar looks at what the class did last, which unit it is in, the outcomes nothing covers yet and when the class really meets on your rotation. It asks what it needs, shows you a complete draft, and redrafts it when you say “shorter warm-up” or “move it to Monday”. Nothing is saved until you say yes, and every change can be undone.

  1. 1 · Radar looks firstLast lessons, the unit, uncovered outcomes and the class’s real next meetings — on a rotating schedule, not Monday to Friday.
  2. 2 · It asks one thing at a timeUsually just the focus, with a suggestion: “Last time was ordering in a café — shall this one be paying the bill?”
  3. 3 · You see the whole draftObjectives, timed activities, materials, homework and linked outcomes, on screen before anything is saved.
  4. 4 · Change it by saying so“Add homework”, “make it forty minutes”. A week of lessons goes in with one “Yes to all”, and any saved change has its own Undo.

Start with your curriculum

The curriculum you actually teach, in the planner

Choose the objectives each class covers this year from a curriculum library, then watch them fill in as you plan and teach. Coverage is a by-product of planning rather than a spreadsheet rebuilt in June.

  • Pick the objectives each class covers, per class
  • Every objective carries its guiding questions and skills
  • See at a glance what is taught, planned, and not yet planned

Turn curriculum into units

A unit is a place to work, not a label on a calendar

Open a unit and find its overview, guiding questions, objectives, key topics and assessment beside the lessons that teach them — in the order you will teach them.

  • Guiding questions, objectives and key topics on the unit itself
  • Reorder lessons, add existing ones, or plan a new one in place
  • Duplicate a unit to teach it again; the planning comes, the dates do not

Every day a class meets, and what you planned for it

Pick a class and every date it meets is listed by month with the lesson planned for it. Select a day and the plan appears as a finished page — click any section to edit it in place.

  • Lesson type, preparation status and unit on every lesson
  • A timed outline that adds up to the length of your period
  • Related tasks and notes sit with the lesson they belong to

Activity sheets and practice tests, from the objectives you already planned

Open a lesson, choose Create Activity, and the objectives and material are already there. Pick the activity types, generate, edit any question, and print a Student version and a Teacher version with the answer key — as real Letter or A4 pages.

  • Eleven activity types and a practice-test mode with a blueprint per objective
  • Every question editable; regenerate one item or rewrite at another level
  • Student and Teacher versions, page numbers, and a preview that matches the printout

Stay ready for what is next

Today, this week, and the shape of the year

Today opens on the classes you teach and the prep still outstanding. Week lays out the timetable. Year shows units as bands across the dates each class actually meets.

  • Today: your teaching day, tasks, notes and notifications together
  • Week: the real timetable, period by period
  • Year: units across the year, adjustable a meeting at a time

Keep the work around teaching organized

Tasks and projects, in one system

The photocopying, the field-trip forms, the marking. Standalone tasks and project tasks are the same records, so a project visibly contains its tasks and nothing is duplicated.

  • Statuses, priorities, categories and deadlines
  • Projects hold their own tasks and show real progress
  • Today and This week views for what is actually due

Remember what matters

The note you meant to keep, where you will find it

One notes system. A note can belong to a lesson, to a unit, or to nothing at all — and it shows up wherever it belongs without becoming a second copy.

  • Capture a note in a keystroke from anywhere in the planner
  • Notes on a lesson also appear on its unit
  • Pin what matters; filter by lesson, unit or general

AI that supports the teacher

A drafting assistant, not a replacement for your judgement

Radar sits inside the lesson editor. Describe the lesson you want and it drafts the sections you have left empty — never overwriting what you wrote. Then refine what is there, in your words.

  • Draft a lesson from a sentence, at the length of your period
  • Only empty sections are filled — your own text is kept, and undo is one click
  • Refine what is there: more inquiry-based, an extension, a student handout
  • Every draft stays fully editable, because you are the one teaching it

Spend less time managing your planning.

Classroom Radar keeps your curriculum, lessons and planning work connected so you can focus on teaching.

Questions

Before you start

What is Classroom Radar?
Classroom Radar is teacher planning software that keeps curriculum, units, lessons, activity sheets, classes, assessments, tasks, projects and teaching notes in one connected planner, instead of spreading them across separate tools.
Is Classroom Radar the same as PlanLark?
Yes. PlanLark is now Classroom Radar, at classroomradar.com. Accounts, classes and plans carried over unchanged, and the assistant formerly called Lark is now Radar.
Who is Classroom Radar built for?
Classroom teachers who plan several classes at once, teach to a curriculum, and change their plans often — the ones for whom planning is a weekly job rather than a one-time setup.
Does Classroom Radar handle rotating schedules?
Yes. Set your timetable, cycle days, holidays and non-teaching days once, and lessons are planned on the dates each class actually meets.
How does Classroom Radar connect lessons to curriculum?
Choose the objectives each class covers this year, then attach a guiding question, a learning outcome, or individual statements to a lesson. Coverage for that class updates as lessons are planned and taught.
What does the AI actually do?
Radar, the Classroom Radar assistant, plans with you. Ask it to plan the next lesson, a week or a unit and it looks at what the class did last, its unit, uncovered outcomes and its real next meetings, asks what it needs and shows a full draft you can change by saying so. In the lesson editor it drafts the sections you have left empty; in the Activity Builder it generates worksheet items from your objectives. Nothing is saved without your yes, and saved changes can be undone.
Can Classroom Radar make worksheets from my lesson?
Yes. The Activity Builder starts from a class, lesson or unit, takes its objectives and material, and generates activity sheets or practice tests in eleven activity types. You edit or regenerate any question, then print a Student version and a Teacher version with the answer key as real Letter or A4 pages.
Does the Activity Builder add pictures to worksheets?
Not on its own. On a reading, Radar suggests what kind of picture to look for; you add an image you have the right to use, with its caption and source, and it prints with the passage. Classroom Radar does not search for or generate images.
Is Classroom Radar free for teachers?
There is a free plan with the planner, lesson editing, curriculum outcomes and 30 AI interactions a month. Pro and School lift the AI limit and add the unit planner and marking progress tracking.
