Lessons that answer back.
Write a lesson once. Teach it on the board, play it as a live quiz or set it as homework. Pupils shade, plot, type, draw and speak their answers, and Montessa marks them as they go.

Lessons
Every page is a lesson pupils can answer.
Notes, lessons and worksheets reflow to any screen, from the classroom board to a parent's phone. Any block can be a question, marked the moment it is answered, and the answers never reach the pupil's browser.
- Maths you can touchFraction models, number lines, area grids, clocks and coordinate grids, drawn from numbers. Pupils shade, place, set and plot, and are marked at once.
- Questions of every shapeMultiple choice, typed answers, gaps, matching, ordering, sorting and labelled diagrams, with partial credit and up to three tries.
- Chapters with gatesA chapter opens when a pupil continues, answers everything or reaches a pass mark. Timed tests are handed in with no going back.
Maths task · Year 4 fractions and time
Shade three quarters of the circle.
Tap the slices to shade them. The circle is cut into eighths.
This is a real Maths task block, drawn and marked by the same code your pupils use.
Live lessons
Turn any lesson into a live game.
Put a section on the board and the class joins from their phones with a code. Split the room into teams, watch the answers arrive and reveal the results together.
- Teams, balanced as they joinTwo to four teams, on the leaderboard, the end screen and the report you keep afterwards.
- Teach modeA timer, a name picker, a group maker, a pen and a blank screen, ready on the board.
- Fair revealsPhones learn whether an answer was right only when the teacher reveals it.

Spreadsheets and worksheets
Real spreadsheets. The worksheets you already have.
A spreadsheet with SUM, IF, VLOOKUP, INDEX and MATCH and pivot tables, marked from the pupil's own sheet. Or upload a PDF worksheet, draw the answer boxes on it, and pupils fill it in on any device.
- Marked by formulaAsk for an answer worked out with a formula, so a number typed in by hand does not count.
- Excel and CSVBring sheets in from Excel or CSV and take them back out again.
- PDF worksheetsPupils fill in your existing worksheets online and download them with their answers written on.
Spreadsheet · Plan the class trip
Work out the total in B5, then the cost per pupil in B6.
Use formulas: try =SUM(B2:B4). Change a cost and watch everything follow.
| A | B | |
|---|---|---|
| 1 | Class trip | Cost |
| 2 | Coach hire | |
| 3 | Museum entry | |
| 4 | Packed lunches | |
| 5 | Total | |
| 6 | Per pupil (30) |
