Maths has always been a strange subject for DS (7, in year 3). He gets good reports on it from school because he can follow the instructions on that day for adding, subtracting, multiplying, dividing. He’s a whizz at times tables.
However… he doesn’t seem to understand the very basic concepts. He REALLY struggles with adding one on to anything. So if you were to ask him what is 6+1, he’s stumped, even though he can tell you one more/less than 6 and can do other additions such as 6+5 by working out with his fingers. He has no accuracy when it comes to counting and often double counts or misses out. He will get it right on maybe the third or fourth try.
Whilst he can do addition and subtraction using columns, tens and ones, number lines etc. he has no idea of this concept in real life, so when he gets to the questions like “Sally has 3 apples and picks 4 more, how many does she have now”, he will in full seriousness pluck a number like 16 out of thin air, or he puts the numbers together and says she now has 34. He has to be reminded every single time that in maths you have to work it out, you can’t just guess. If I said to him, what is 3+4, he could do it, but only after he’s been reminded to actually work it out, or else out come the random answers again. These random answers are not even mathematically possible sometimes, so a question on addition might result in him saying an answer that is lower than the starting number, so would not even make sense for addition.
School haven’t picked up on this at all. Is it something I should be worried about or is it normal at this age and I just need to give him more time? Honest answers accepted!
