how about to a P5 boy who fail math? any place he can go to make him improve. He failed badly in P2…

hi everyone, I am new here. My boy is in P5 this year, failed his CA1 and SA1 math. I am currently looking for some help. I sent him to one enrichment centre, only 6 students, and he came home telling me half of the time is spent waiting for the teacher because she will go round coaching the students individually. I like the centre as they group the problem sums according to the different strategy used, but my son is not absorbing as he came home forgetting how to do.What kind of help should I get? appreciate your contributions. thanks.
