Just bumping this to ask for more help re math facts to 20... I've given up on timez attack as DD is too unfocused to even notice and read the sums reliably before the time is up, let alone answer them. We've been trying this one today:
http://www.harcourtschool.com/activity/thats_a_fact/english_K_3.htmlI have no memory of mastering these facts myself. Or even of my first child working through this to be honest (we had MUCH bigger problems with literacy than addition/subtraction facts, I guess, so this just happened in the background and was never poor enough to be anyone's primary concern). So for something so basic I feel rather out in the dark. I can tell that addition/subtraction facts (not concepts) within 20 is a problem for my DD but I am not clear what the ideal way to fix it is.
Doing the sums on the link above she is slow but accurate within 12, very slow and less accurate within 20 (but struggling to attend at all). Note that she is in general slow with most things. Slow to talk, slow to respond... Presumably this is ADHD related. My husband is a bit like that, his sister is actively difficult to talk to she is so slow to reply... So slow might not mean too much.
She's using her fingers a lot or just staring into space and I feel like maybe I should be teaching her better methods, but I am not sure what they would be. When I am faced with sums within 20 I either "just know" the relationship, or if I can't remember (my memory is impaired by a health problem), then I will very rapidly break it down using the gaps either side of 10... But I am not sure if this is what I should be teaching her? Or how?
Does that make any sense at all?
