From a lesson to a printed worksheet, objectives first.

Pick a class, lesson or unit and PlanLark already knows the subject, grade and objectives. Choose activity types, set the language and level, and Lark generates the items and checks each one against the objectives. Every question is yours to edit or regenerate. The preview shows the actual pages that will print — a Student version with no answers and a Teacher version with the answer key.

What the AI can do

AI generates the items from your objectives and source material, checks them, and regenerates any single question you ask it to. It suggests an image to look for; you add the image.

The PlanLark Activity Builder showing a Student preview of an activity sheet as real pages, with the Reading comprehension activity, its What-to-do panel and key vocabulary box

Student preview — the pages on screen are the pages that print.

Context aware

Connected to the weekly planner, schedule rules, and unit structure.

Teacher controlled

You review and refine changes instead of handing the whole process away.

Built for school reality

Designed around shifting timetables, real curriculum work, and mid-week edits.

How teachers use it

Where Activity Builder fits into the planning week.

Eleven activity types: matching, fill in the blanks, sorting, reading comprehension, multiple choice, true/false, short answer, vocabulary practice, sequencing, word search and diagram labeling.

Practice test mode with a blueprint that spreads questions across your objectives.

Objectives come from the class curriculum, the lesson or the unit — or you type them — and objective coverage shows how many items practise each one.

Edit any question or answer in place; regenerate one item, add more, or rewrite an activity at a simpler or more challenging level.

Student version (no answers) and Teacher version (answer key with evidence) from the same sheet.

A paginated preview in Letter or A4 that matches the printout: activities kept whole where they fit, headings never left alone, page numbers on every page.

Reading and language controls: the language of the sheet, a reading level from primary to advanced (including CEFR A1–C1), and difficulty.

Three worksheet styles that print cleanly in black and white, a “What to do” panel with clear instructions under every activity, word banks, an optional key-vocabulary box and callouts.

A picture slot on readings: Lark suggests what to look for; you add the image with its caption and source.

Sheets save with your lesson, can be duplicated, and reopen in the editor any time.

Classroom scenarios

Real reasons teachers reach for this feature.

The lesson is planned, the worksheet is not

Open the lesson, choose Create Activity, and the objectives and material are already filled in. Pick matching and short answer, generate, print.

A practice test before the unit test

Switch to Practice test, set the share of questions per objective, and get multiple choice, true/false, matching and short answer sections with marks and a teacher key.

A2 German reading practice

Paste a short text, set German at A2, and the passage, questions and student instructions come out at that level. Simplify or raise the level of any activity afterwards.

Examples

What it looks like when a teacher actually uses it.
