Aids in RE course? Wrong — they are used in maths classes (10,4)

Ross

I believe the answer is:

cuisenaire rods

'they are used in maths classes' is the definition.
(cuisenaire rods are learning aids for maths)

'aids in re course? wrong' is the wordplay.
'wrong' is an anagram indicator.
'aids'+'in'+'re'+'course'='aidsinrecourse'
'aidsinrecourse' is an anagram of 'CUISENAIRE RODS'.
