7 Year old who who gets distracted/ Wanders very easily.

Firstly thanks so much for all the help and I love the TSG program, it has been a real blessing in our family. I have a 7 year girl old who who is very easily distracted. When we give her chores or ask her to go/do something she normally either gets distracted before she gets there or starts and then ends up somewhere else. She is a Yellow Personality type, and is quite spontaneous/dramatic in her nature. We have 5 children with 9 being the oldest and she is normally the worst at leaving messes behind her. She tends to go from one thing to the next and not clean up, she is very creative and imaginative in her play. We give her an instruction to clean up what she is doing, but before she has finished, she has gotten distracted and moved on to the next thing. With 5 small children it can be quite a big job with her following through checking what she has been up to and giving her a correction and extra chores, because it ends up being an extra chore for not doing an extra chore because she didn't clean up, and then there is the extra chore for not accepting the no answer of leaving a mess and not cleaning it up. And because she gets distracted so easily this process goes on and on. I think she is a bit muddily in her thinking and can only focus on one thing at a time. And because she is quite creative she tends to be in her head a lot. Sometimes she can be looking at me with a calm face and body and say OK when I give her an instruction. But when I ask her what the instruction was 1 minute later she cant remember, and I don't think she is being dishonest. Any thoughts.
