I am on these forums as I am a TA, however, at the moment I am asking for help with my own daughter. She will going into year 4 in September and her ability fluctuates a lot each day. For example, one day she will be able to instantly add and subtract in her head numbers with three decimal places and read paper backs with fluency and expression. The next day she will quite literally struggle to add one to a number and struggle to read even CVC words. She really suffers with fatigue due to a medical condition and I'm guessing this is the cause, but I'm going round in circles as no one can help me. Can anyone tell me, are there any other causes for children to suffer with this extreme fluctuation in ability? Also, can anyone think of anything to help? Her teacher has no ideas at all, but keeps her at the lower level in the class as half the time she can't achieve it, but I don't feel like she is making any progress.
