Presentation: Collaborative Maths Quiz

Collaborative maths quiz

In a team of 3 you will write 1 round of 5 algebra questions with a mark scheme that awards marks for method as well as the final answer. Another team will sit your round and mark it with your scheme, and you will sit and mark theirs.

While the register is called: write your name, class and date on your worksheet, sit in your 3, and read the Team roles table.

Starter question: Calibration question 2: solve 5x − 7 = 38. Write the answer and the 2 steps a marker would look for.

DCF: Interacting and collaborating → Collaboration You are assessed on how you share 1 document, not on who is quickest at algebra

Supply teacher script (no subject knowledge needed)

Hand out: one worksheet per pupil. Put pupils in threes. If computers are available each 3 works in one shared document in the class folder named quiz-round-TEAMNAME, all 3 editing at the same time. If there are no computers, teams write their round on the sheet and physically swap sheets at Step 4; tick “paper” instead of checking version history. You do not need to check the algebra: the worked example settles any marking argument.

Say aloud: “Name, class and date at the top. Sit in your 3. While I take the register, answer the starter question in rough: solve 5x minus 7 equals 38, and write the 2 steps a marker would want to see.”

Starter answer: x = 9. Method: add 7 to both sides to get 5x = 45, then divide both sides by 5.

Your brief: 1 round, 15 marks, 3 roles, 1 shared document

Step 1: agree the 3 roles and write names against them in the table. Everyone edits the same document; the roles say who is responsible for what. Write your team name and document name: quiz-round-TEAMNAME.

Question setter

Drafts all 5 questions into the shared document, 1 per numbered heading.

Answer checker

Solves each question independently and flags any disagreement with a comment, never by overwriting.

Mark-scheme writer

Splits each question into method marks and answer marks so the round totals 15, in wording a stranger can follow.

Step 1 on your worksheet · 5 minutes with the starter Comment, do not delete each other’s work

Slide 3 of 7 · Step 2: calibration · Maths · Year 9

5 minutes

Step 2: work through the 4 calibration questions together

This is the level to aim for. The answers are printed on your sheet so you can see exactly how much working a 2-mark question needs. Then tick 5 different topics from the topic table, 1 question each.

#	Question	Answer, with the method a marker would look for
1	Expand and simplify 3(2x + 5)	6x + 15. Method: multiply both terms inside the bracket by 3.
3	Factorise x² + 5x + 6	(x + 2)(x + 3). Method: 2 numbers that multiply to 6 and add to 5 are 2 and 3.

Step 2 on your worksheet · 5 minutes No 2 questions on the same topic

Slide 4 of 7 · Step 3: write your round · Maths · Year 9

15 minutes

Step 3: write your 5 questions and the mark scheme

Fill in all 3 columns for every question before you swap: the question as the other team will read it, the answer and method marks, and the marks. The total must come to 15 marks. Every question must have a worked answer, or your round cannot be marked.

#	Question as the other team will read it	Answer and method marks	Marks
1	Expand and simplify 4(x − 3) − 2(x + 1)	2x − 14. M1 for 4x − 12, M1 for −2x − 2 (both signs correct), A1 for 2x − 14.	3

Step 3 on your worksheet · 15 minutes Disagree? Leave a comment and confirm, never overwrite

Supply teacher script (no subject knowledge needed)

Say aloud: “15 minutes. Setter drafts the questions, checker solves every one independently, scheme writer splits the marks into method and answer so the total is 15. Look at the model row on the board: M1 is a method mark, A1 is an answer mark, and the scheme says what a wrong sign loses. If the checker gets a different answer, leave a comment and let the setter confirm; do not delete their text.”

Quick check: the worked example round is Team Cadair’s: Q2 (2x − 3)(x + 5) = 2x² + 7x − 15; Q3 2x + 9 = 5x − 12 gives x = 7; Q4 6x² + 15x factorises fully to 3x(2x + 5); Q5 nth term 4n − 1 gives 10th term 39 and n = 20 for the value 79. In the example, the checker caught a sign slip in Q2 by comment at 10:21 and the setter fixed it at 10:23.

Walk the room: check each team’s marks column adds to 15 and that no 2 questions share a topic. A question with no worked answer in the middle column is not ready to swap.

Step 4 & Step 5: sit another team’s round, then mark it with their scheme

Step 4 (10 min): swap with another team. Sit their round under exam conditions, showing your working.

Step 5 (10 min): mark the round you were given using its team’s mark scheme. Write a comment on each question, not just a tick. Record the author team and the total out of 15.

#	Marks out of	Marks given	Your comment to the author team
1	3	1	M1 for 4x − 12. The second bracket was multiplied by −2, so it must give −2x − 2, not −2x + 1; the −2 has to hit both terms.

Steps 4 and 5 on your worksheet · 20 minutes A comment names the error and the correction

3 minutes

Step 6: read your feedback and record the 1 change you would make

Read the comments on your own round and write the 1 change you would make under “What we would change”. Then tick each success criterion your team has met.

All 3 of us contributed to the same shared document, and the edit history shows it.
We agreed who was responsible for what before we started writing, and we stuck to it.
When we disagreed about an answer we left a comment and resolved it, instead of deleting each other’s work.
Our mark scheme is clear enough that a team who has never met us could mark our round without asking us a question.
We gave another team specific written feedback, and acted on the feedback we were given.

Quick-check answers before handing in

Check these against your sheet before your worksheets are collected.

Question	Correct answer
How many marks must a round total, and how many questions?	15 marks, 5 questions, 5 different topics.
What should the answer checker do when they disagree with the setter?	Leave a comment and resolve it; never overwrite the setter’s text.
Expand and simplify (2x − 3)(x + 5).	2x² + 7x − 15; the last term is −3 × +5.
