Mathsfactor has been a huge help for my 8 year old. This time last year (when in Year 2) we began to realise that our child couldn't even take 1 away from 10. There simply was no understanding at all about the concept of subtraction. Worse yet she had somehow absorbed that if you guessed basically near to the right answer it was correct. So in fact if she answered 5-3 = 3 her teachers would say 'well done, that's right'.
When we had a meeting with the school to discuss our confusion about our child's subtraction, we explained that we thought our child needed more practice and asked if they could recommend anything or if we could purchase the text book(s). The school's response was to say they don't recommend additional work or practice books as a general rule. We were basically told that 'children develop at their own rates' and left to our own devices. Worse yet, our daughter was convinced she was 'no good at maths' because one of her teacher's had helpfully told her so. Perhaps we're overly ambitious, but we wanted our children to be able to leave primary school able to add, subtract, multiply and divide and possibly have some geometry/ early algebra to boot (which clearly is asking for the moon at our school). We just felt that if things continued as they were we'd be lucky if she could multiply 4 x 4 when she went up to secondary school.
Mathsfactor happened to be starting up just as we hit these troubles and we tried the free 1 month trial. We were in total despair and felt it couldn't hurt to try it out. My daughter took to it like a fish to water. She adores video games and loves timed challenges. Yes, the homeworks run 20 - 30 minutes. And yes, if they're under 8 you probably will have to sit there and type in their answers. Sure, the homeworks can seem a bit repetative and occasionally (like the x1 and x10 times tables) she 'already knows this' and has to weather the repetition. But I wouldn't have passed up the joy of seeing her pride at genuinely beating her father to subtract 9 from 63 for all the tea in China. She was over the moon and Dad was proud as punch.
The school our daughters go to isn't awful, but it isn't great either. Maths homeworks are few and far between and for whatever reasons the way they teach math (which primarily seems to be giving them the same test week after week until they pass it) just doesn't suit our child.
One year on and our daughter can add and subtract 1 - 10 from numbers up to 100 (and frankly beyond now) with ease. She's working through her times tables now and loving it. To see her full of pride and hear her say 'I love math now' is just bliss. Mathsfactor may not suit everyone and may well be geared for us oldies - but boy oh boy has it made a difference for our child.
One final thing - there seemed to be a lot of complaining about mathsfactor, which is why I felt I should write in, because our experience has been brilliant. One of the main issues in the discussions seems to be that the practices started at much too easy a level. You can adjust where your starting point is now.
