teacherwith2kids:
All I will say is that as a parent turning to mathsfactor gave my child 3 things the school wasn't:
clear explanation of how to technically 'do it' which conformed to current methods/ terminology
opportunity at review, repetition and practice
encouragement (the beauty of video is the teacher is always cheery)
I suspect you are a great teacher and probably do make sure every child in your class understands 10 - 1 is just counting back one (by doing it on paper, showing them to count back on a number line, showing them to count back on fingers, showing them 10 objects and taking one away and counting them all up, etc....).
I wasn't there so I've no idea how it was taught - but I just had a child staring at me blankly when presented with a sheet with simple subtractions of numbers under 10: 10 - 1, 4 - 3, 8 - 6. She clearly didn't get it whatsoever. This was Easter Y2 - not YR, not Y1 - but EASTER Y2. We'd been asking for 2 years + why x or y wasn't happening at our school when it was at other schools in the area regarding maths and had been repeatedly told not to compare with other schools.
For us mathsfactor ensured that those number bonds (more than just what makes 10 or 20, but what makes 4, 5, 6, 7, 8, 9 and then applying that to additions/ subtractions with bigger numbers) were thoroughly learned and understood. It ensured that place value and technique were clearly explained and absorbed.
In a school which clearly wasn't putting in the 5 numeracy hours. (or should I rephrase - was wasting their 5 numeracy hours with poorly organised, structured tuition)....
In a school which coped with lack of understanding by simply moving children down a group and giving them easier work....
In a school which offers no additional support/ maths intervention in KS1....
In a school which refuses to offer suggestions for additional support at home (workbooks, on-line games, books, etc...).....
...what do you expect parents to do?
Please do us parents struggling in mediocre to appalling schools a favour by not getting on here and pronouncing 'it shouldn't be done' - I paraphrase.
I personally feel that it would be a travesty to leave primary school unable to add, subtract, multiply and divide. It is quite clear many children (>30%) do at our school - and I'm certain my DD1 would have been in that category if I hadn't intervened and trust me there isn't a day that goes by I don't thank the stars above for discovering mathsfactor which solved many of our issues for DD1.
We do the homework because it's fun and not overkill (just 20 minutes 5 x a week), but given the school's unreliability (homework regular pre-Ofsted and now right off the agenda) please don't blame a parent for wanting consistent, clear and practical maths tuition and seeking it outside if their school is totally failing their child.
