My DS is in Y2. Started school quite able and above expected levels, but has slowly dropped and is still hitting expected targets but I've noticed that he will grasp a topic quite quickly when we're going through things with him, but then a day later it's completely gone. I think this is the issue with his subjects, especially maths. They are doing times tables and despite us going over it nightly and his grasping it every time, the next day it's completely gone out of his head so he'll get low marks the next day in this morning mental maths quiz. Spellings are similar but seem to stick around a bit longer than numbers. Is this something to be concerned about or normal? His teacher isn't worried because he's still hitting the expected targets but I'm concerned that he seems to be noticeably struggling compared to where he was and want to help if he needs it.
