Advice from Teachers needed - year one homework, hundreds, tens, units

[paulinec]

Hi there
ds1 maths homework this week is hundreds,tens, units place values e.g.

645 = 600 40 5

It sometimes infuriates me that the teacher cannot do a little background note for parents to indicate how she has been teaching the subject. I do not want to start rabbiting on, and totally confuse him and go against what she has said.

Therefore, could any of you delightful teachers give me a little inside info so I am not going against the grain. He has two huge sheets to do over the weekend.

Thank you all so much

btw paulinec, do you have any clever ideas about teaching times tables? I remember learning them by rote so even now I go through the chant in my head if say, 6 x 9 doesn't immediately pop into my head. Does something recorded exist these days, like a CD with times table songs?

There's a useful resource when working with H, T & U which you can make yourself at home. Basically, if you were working with the number 146, you would make 3 arrow shapes.

The first would say 100 with the 100 sitting in a rectangle, and the pointed end of the arrow pointing to the right (towards the units end).

Then, you make another arrow shape saying 40 which has the same arrow shaped end but a smaller rectangle for the 40 to sit in, so that it cannot overlap the Hundreds bit.

Then, you make a final smaller arrow shape for the units saying 6. Again, you have the arrow bit, but the 6 is in an even smaller rectangle so that it cannot overlap the hundreds or tens.

When you pile them up with the arrow parts together, you see 1 4 6, but when you take them apart, you see 100 40 6

Does that make any sense at all? It's really hard to explain!

I think so. I'll follow your instructions and make it up, arrows & all, tomorrow. Thanks!

god, im really looking forward to all this when DS starts school

hi sauce, i think early learning centre do times table songs cd. Also go on ebay and get a leap frog twist and shout, they are great, you can get them for addition, subtraction, multiplication and division they are fantastic.

Littlefish, will def try the arrows.

I think I've seen it... it's a cylindrical shaped thing, isn't it? LeapFrog does great stuff.

This is called partitioning. You should be able to find links to it on the parents part of the dfes website. Important skill to lay down in year 1 and 2 to underpin understaniding of the number system.

Years 1 and 2 correspond to...? My dd is in the Swiss school system & is 6.5 yrs old. She's in what's roughly translated as "first year primary".

Year 1 - children are 5 at the start of y1 and 6 during y1

Year 2 - children are 6 at the start...
