Cover teacher: you need no subject knowledge

What this practises: judging a piece of digital content against success criteria and suggesting improvements, then writing feedback as you would in a comment box online. Pupils read the first draft of a maths help page made by 3 invented Year 6 pupils for Year 5. They check the maths (multiplying a 2-digit number by a 2-digit number), score the page, proofread a paragraph, redraft the method and write a kind, useful comment.

Print: this sheet, one per pupil, and the stimulus sheet “Maths help page: first draft”, one between two. No computers are needed. The web page is printed on paper. Pupils need a pen and a highlighter. No calculators.

Run: 5 min read the stimulus sheet aloud · 5 min Step 1 · 8 min Step 2 · 10 min Step 3 · 8 min Step 4 · 12 min Step 5 · 7 min Step 6. Total 55 minutes.

Collect: this sheet. Steps 4 and 5 give the literacy evidence (proofreading, editing and redrafting). Quick checks: 47 × 36 = 1692. The page says 423 because the second line should be 1410 (47 × 30), not 141: the group forgot the placeholder zero. The 8 errors in part 6 are: here (capital H), befor, dont, freind, the missing question mark in sentence 6, We was, it help, easyer.

What you are doing

Cerys, Osian and Tomos made a help page for their school website. It should teach Year 5 how to do long multiplication. Their teacher wants you to check it before it goes online.

You will check the maths, score the page, fix the writing and help them make it better.

Step 1: purpose and audience

Read the whole page on the stimulus sheet. Answer in short sentences.

QuestionYour answer
(a) What is the page for? (its purpose)
(b) Who is it for? (its audience)
(c) Who made it?
(d) After reading it, what should a reader be able to do?
(e) Where will people read it? Why does that matter for the layout?

Step 2: check the maths

Do 47 × 36 yourself before you look at the group’s answer again.

(a) Estimate. 47 is about ______ and 36 is about ______, so the answer is about ______.

(b) Column method. Show your working in the box.

(c) Check with the grid method. Fill in each box, then add them all up.

×407
30
6

Total: ______ + ______ + ______ + ______ = ______

(d) The group wrote 47 × 36 = 423. Which line in part 5 is wrong? What should it say, and why?

(e) How could the estimate in part 7 have helped the group spot their mistake?

Step 3: score the page

Score each success criterion: 3 = does this well, 2 = partly, 1 = not yet. Give a reason and use part numbers.

CriterionA good help page…ScoreReason (say which parts)
Contenthas everything a reader needs: a method, an example, tips and a way to check.
Accuracyhas correct maths and correct spelling, punctuation and grammar.
Layoutis easy to follow, with the most useful parts easy to find and read.
Suitable for Year 5uses short, clear sentences and nothing that could confuse or trick a reader.

Why do you think the group put the big rocket picture (part 2) so near the top? Was it a good choice?

Step 4: proofread the top tips

Part 6 has 8 errors. Highlight each one on the stimulus sheet. Then fill in the table. The kind of error is spelling, punctuation or grammar.

SentenceErrorCorrectionKind of error

Which strategy helped you find the errors? (For example: reading aloud in a whisper, reading one sentence at a time, checking each capital letter.)

Step 5: redraft the method

Part 4 is one very long sentence. Rewrite the method as numbered steps that a Year 5 pupil can follow. Each step should do one thing. Include the placeholder zero, and finish with a correct example (47 × 36, or 23 × 14).
