I've read this and just don't understand what ds is being asked to do. This is exactly what the sheet says:
"Doubles over 10
To work out these doubles:
1. double the first number 2. double the second number 3. add the two answers together!
+ = _
+ = _
+ = _ "
Do they mean the first line is 12 + 12 = 24, then 24 + 24 = 48, then add 24 + 48 to make 72? There are six questions like this in total, and the largest number is 63 - seems a bit hard for a 6 year old?
I have to say, as a teacher, I am dismayed at the lack of explanation that goes out with some maths homework, the instructions are hardly clear ( and this is at least the second example this weekend!) Although children SHOULD remember what method they used in class, they don't always ( especially the littlies-I teach yr 5/6 and if mine don't understand they are expected to find out-but then I'm mean ) so perhaps teachers should ensure parents are given the support they need so they can help if their children need it, rather than spend the weekend baffled or on Mumsnet!
As well as teach yr 5/6 I also run family learning sessions for our parents, especially in maths. This is not because our parents can't understand maths ( although some do struggle!) but that they don't understand the methods and ways of teaching we have today. I do think some teachers asuume parents are mind readers and know what we mean and how we teach different concepts. We just need to be more explicit
We have been through this as well. It's not easy when the school then says we teach them lots of ways so they can all find their own preferred way. So even if you do it the 'right' way one week, a month later your kid we tell you no not that way.
The example given confuses many cos we were always taught add the units, then the tens, then the hundreds & so it seems back the front. Who knows if it's an improvement? Our 6 yr old when he does these in his head almost always forgets what we would call the '1 carried across' when the two units total 11 or more!
