Part I: The Elements of OTTER Maths Question Templates

The majority of question templates have five elements, as in Example 1 below.

  • an instruction sentence
  • a task sentence
  • a panel of multiple-choice options (two – six options)
  • the letter of the correct option
  • an explanation or reminder of why the answer is correct

 

Example 1


Which option(s) correctly complete the sentence? INSTRUCTION SENTENCE


The spokesperson did not say so directly, but she _________ that the company director had been blackmailing clients.  TASK SENTENCE


  1. intimated            MULTIPLE-CHOICE OPTIONS
  2. implied
  3. insinuated
  4. inferred

Answer: a, b, c               CORRECT OPTION


Explanation: Although ‘insinuated’ has a more negative connotation than ‘intimated’ or ‘implied’, all three verbs mean ‘to say something indirectly’.      EXPLANATION

 

But some OTTER questions have fewer elements, which may or may not appear in a different order as per the example below. 

 

Example 2

Solve the equation below.  INSTRUCTION SENTENCE   



4x – 1 = 11             TASK SENTENCE (I.E. THE PROBLEM)



  1. 1
  2. 2
  3. 3
  4. 4


Answer: c     CORRECT OPTION



------------------------------------------------

4x – 1 = 11                                                WORKED EXAMPLE WITH SHORT NOTES  


4x = 12      Add 1 to both sides


4x/4 = 12/4     Divide both sides by 4


x = 3
