Support management acquiring large classroom item (10)

I believe the answer is:

blackboard

I'm a little stuck... Click here to teach me more about this clue!

'classroom item' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'support management acquiring large' is the wordplay.
'support' becomes 'back' (to back is to support or endorse).
'management' becomes 'board' (eg the board managing a business).
'acquiring' means one lot of letters goes inside another.
'large' becomes 'L' (eg in clothes sizes).
'back'+'board'='backboard'
'backboard' placed around 'l' is 'BLACKBOARD'.

Can you help me to learn more?

(Other definitions for blackboard that I've seen before include "Surface for chalk" , "Traditional teacher's aid" , "where he might chalk up a win" , "Teaching aid" , "What's written on in the classroom" .)
