Never encountered this before (and what a lovely problem to have!).
A little boy in my reception class is streets ahead in reading and numeracy. In days gone by I would have had him working with a TA while I was doing teaching inputs with the rest but I have three autistic children and frankly not enough adults.
He is thoroughly enjoying himself in the sand pit atm, so I'm very reluctant to pull him out of continuous provision to teach him.
Any advice?
