Y2 maths

[saragrey]

What are your Y2 children doing in maths at the moment? Have looked up info on internet about what they are meant to do, bu thte more I read about it, the more confused I get!

[thinkingkindly]

Division is the new thing DD is studying; she has done basic multiplication.

Partitioning - ie 394 = 300 + 90 + 4. Adding units of ten, and units of one, then multiples of ten, multiples of one.

3, 4 times table

Still learning to tell the time.

[Oakmaiden]

Not a lot as far as I can gather. Dd doesn't seem to have done multiplication at all yet (not even 2,5,10) let alone division. And I am fairly sure they SHOULD have....

[saragrey]

thinking - is she working above, on or below average?

[IndigoBell]

Easiest way is to just buy a Y2 book from WH Smiths...

All kids will be doing different things in Maths at the moment, depending on what topic they are studying, and what ability they are.....

See ICTgames - an excellent website with games to support most of the Y2 objectives.

DS2's maths homework this weekend was telling the time, each question gave the time in words and they had to draw the hands on a clock and then write the time in numbers eg 10.15.

They have also been doing times tables: 2, 5 and 10 I think.

[ragged]

Lots of quite clever division (like 72/12 or 64/8), hot on the heels of times tables (seems like all the timestables).
I think he might be in the top maths group, though. I imagine the bottom sets are still going thru 2s and 5s timetables and doing rather simpler division (like 30 / 10).

[Oakmaiden]

You see this is where I get really worried about dd's school - where she is in the top maths set but doesn't seem to do very much at all {wanders off muttering to self}

[saragrey]

I have noticed that my ds is doing adding and taking away tens and units at school and gets them all right. Should the teacher be giving him harder adding and taking away sums, with hundreds? Or is that left until Y3?

[southernbelle77]

DD varies but is definitely doing muliplication (2,3,4,5 & 10). they have Ben doing a lot of each (+,-,x,/) with different amounts of money. The top groups have been doing fractions too. Lower groups still doing number bond work I think.

[SofaQueen]

They are doing angles (right, obtuse, acute), grids and positions, bar charts, sequences (identify, define and continue), and division. They have already done all the tables to 12x12.

[mrz]

456 + 278 =
312 - 149 =
45 x 5 =
73 / 5 =
30 x 80 =
partitioning hundreds tens and units and units and decimals
number factor families for two digit numbers

[saragrey]

Are they supposed to be doing decimals and acute angles in Y2? I didn't see that in anything I read. (Am starting to get worried.)

[ragged]

Just barely started mentioning decimals here, nothing on angles.
DD (top set in yr4) is doing a lot on angles.
Sorts of problems that mrz listed is what y2 DS might be doing, although some of that looks a bit too tough for DS to get right answer reliably.

[SofaQueen]

Just picked up DS1's homework pack for the break and the sorts of problems mrz listed are similar (but more focused on division now, rather than the addition and subtraction). They are doing basic decimals (tenths, but not hundredths or thousandths).

What are number factor families?

[mrz]

Those are actual questions my class did today

they had to partition 3.8 & 565

write the factor family for 13 + 68 = 81

54 x 10 =

36 + = 40

[thinkingkindly]

saragrey, dd is in the top set and these are the things she has just started (had parents evening yesterday, so am clued-up).

She hasn't 'got' division yet - it is something that I am going to work on with her, though she has done halving and quartering. Multiplication is also fairly new (I don't think she could do mrz's sums at the moment). Partitioning is fine, and she can add tens and ones. She has only done 2s, 5s, 10s, 3s for times tables. Am just going to do 4s and one of the others (can't remember which) with her at home.

We have done adding up money, including decimals (but at a fairly simple level).

[thinkingkindly]

I don't know what the factor family is either! Had to ask DD's teacher to explain all terms (such as partitioning).

[PoppetUK]

DD is doing partitioning at the moment which she finds easy (thank goodness because English homework was tougher). I know she's doing 3/4 times tables having covered 2,5,10's. I'm not sure what the top tables are doing.

She hadn't a clue what number bonds were and needed to use fingers the whole time. We are just trying to show her things like 3+7 = 10 13+7=20. Her maths is a bit gappy from her education else where.

[drzeus]

There is an excellent book called Maths for Mums and Dads which explains the methods used in school to teach maths. I work as a TA in Year 3 and would thoroughly recommend it. DS2 is in year 2.

[SofaQueen]

Can you tell me what it is? Can't believe I've taken up to multi-variable calculus and I can't figure out what number factors are - are they groups of number which multiply to form the same answer?

Forgot that money = decimals. Duh!

[mrz]

the factor family is

13 + 68 = 81
68 + 13 = 81
81 - 13 = 68
81 - 68 = 13

it also applies to multiplication & division for example

13 x 24 = 312
24 x 13 = 312
312 / 13 = 24
312 /24 = 13

[mrz]

We use Big Maths so my class do a weekly 40 addition and multiplication questions in 90 seconds plus 10 questions of the type I posted above.

[SofaQueen]

Thanks, mrz - in other words, the commutative property as I learned it in primary school.

[thinkingkindly]

I have just ordered that book!
