Yes, DD2 did from 6-9 she was far more likely to get in a rage than when she was little.
DF said her TDDs threw better tantrums at 7 than 2.
Since DD2 was impossible to reason with when in a rage, we just used to say 'room until you want to be nice'.
'Nice' being short hand for co-operative, not whiny and not trying to wind your elder sister, mother and or Father up. The world does not revolve around you and you cannot always have your own way, sorry.
When she was small, she would reappear in 10-15 minutes, generally being reasonable or I'd go and find her.
When she was older she'd play on her lap top and DD1 and me have been known to forget her, the peace was do nice 
I think at 6-7 it's still little child frustrations, by 9 it's wanting a bit of control over their lives, and not being able to have it.
Once DD2 got to being old enough to leave in her own or walk to the shop herself she got way better.
With six year-olds really all you can do is ignore as much as possible and lots of hugs when they are being nice. You cannot reason with them when they are in a rage, you sometimes can when they have calmed down.
However, you have to accept that doesn't stop them having the same strop about the same unpalatable fact of life tomorrow.
