I can't do ds home work year 4

[Dustybrain]

DS is in year 4. And I can't do his home work. Not literally. But unless I use a calculator I don't know the answer. But obviously I can't just give him the answer. But I have no idea how to explain how he could work out the answer.

I have learning difficulties so I don't know how to help him

Give us an example, we might be able to help

Get an app called Symbolab

it will show you some of the steps for free. More detailed steps with a subscription.

you just take a picture of the problem with your phone, confirm it got the correct problem, and you are good to go.

I have a PhD in a scientific field and I was literally in tears trying to do dd’s maths homework with her from about Y4. We aren’t taught to do arithmetic without a calculator past a certain age and the way they teach it now is completely different to how we learned it in school. Honestly, I had to watch YouTube videos and re-teach myself how to do it.

Whiterose maths and ncetm (national centre for excellence in maths) have free exemplification videos with current ways of teaching things.
At this point in the year they will be focusing kn place value, so go and look up year 4 place value kn those and get help.

Primary teacher here. Some of the methods used in maths from Year 2 up are horrendous (and often make no bloody sense IMO!) Feel free to post the question here and we might be able to help.

@Dustybrain don't beat yourself up. My dss is doing a maths degree at a Russell uni and he couldn't do dd's math homework (his sister).

The way it is explained these days is so much better than when I was at school but they do use terminology that didn't exist in the 80's & 90's when I was at school...I have an English degree and I struggles with her English homework in Y1 cos I had no idea what the terms were.

Depending on how much your LD affect your ability to do maths and to learn new maths methods so you can explain it to him I think your best way forward might be to post here and then try to explain. Or to talk to his teacher.

Dd is in year 6 and my ability to help stopped in year 3. I'm a quantity surveyor! Don't beat yourself up over it.

What's times tables got to do with dividing . And never heard of a perpendicular

I also have a PhD and can't do primary school level maths

Times is the inverse of divide. So if 5x4 is 20, then 20/5=4 and 20/4=5. So , if you know your 4 times tables, you know 4x12=48 so 48/4 must =12.

Perpendicular means at right angles to, so in + the two lines are perpendicular

Dividing is the opposite of multiplying, so it is another way of testing memorisation of the times tables. For example, if you have memorised that 9x3=27 then you also know "for free" that 27 divided by 9 = 3 and that 27 divided by 3 = 9.

A perpendicular line meets at right angles to another line - so hopefully your walls are perpendicular to your floor at home, for example, and the two lines that make up a capital T are perpendicular to each other.

Sorry I have no idea what you mean 😭 I don't know times table at all. Only 2s 5s 10, that's it .

Times tables and dividing are part of the same thing! 5 x 4 = 20. So if you had to work out 'something x 4 = 20' - you'd divide the 20 by 4 to find the answer. Kids who are secure in their times tables might even be able to say to themselves 'what times 4 is 48' - go through their 4 times tables and when they get to 12 they've found the answer.

Words like perpendicular you can just google. It just means at a right angle - as if you lie a pencil flat on a table and another one standing on its end - the two are perpendicular. So squares, rectangles have perpendicular sides.

Year 4s should know their 3 and 4 times tables and the associated division facts so the first question should be ok for them. If not, counting in 3s and 4s will help
For Q2, they need to recognise the pattern, so 5,55,105,155,205 etc.
For Q3, it's another inverse. So, if 393-127=266, then 266+127=393.

Perpendicular are 2 lines that meet at a right angle, so the rectangle has perpendicular lines. Parallel lines never meet so the rectangle also has 2 pairs of parallel lines opposite each other (like a train track). Division is the inverse or opposite of multiplication. If you know that 3x9= 27 you also know that 27/9=3 you also know that 9x3=27 and 27/3=9.

Parallel lines are one that run like train tracks and never meet, perpendicular meet at right angles.

Can you use something in your house to do times tables like pasta or something you have a lot of so 6x8 would be 6 groups of 8 pasta shells if that makes sense seeing things visually helps me

I wish i hadn't asked 🤣

Op I had the same problem with my eldest son. I ended up going to adult education classes to brush up on my maths skills

Yeah that won't help me though. Great you did it though .

Definitely do things practically. Smarties are useful as you can eat them too!
So, for 6x8, make six groups of eight and count how many altogether ( or, if your son can count in 8s, even better.
For 48 divided by 4, count out 48 smarties and share them into groups of 4, how many in each group?

OP the best thing you can do is teach your child independence . Do they have a times table book? If not look up “times table square” on google and print that off. Your child can look up the answers using the times table square. That will help them learn the times tables and learn that divide is the opposite of times.

For 27 divided by 3, 27 smarties shared into 3 equal groups, should have 9 in each!
9x8 is 9 groups of 8( or 8 groups of 9) which means you need 72 smarties😊

Question 1 6x8=
So if you don't know it do 8+8+8+8+8+8 which is the same answer.

Question 2 is- 5, 10 etc up to 50

Question 3 so u just reverse it - 127+266=393

Question 4 parallel sides are ones that are opposite each other. Like the rectangle. The hexagon (the one with 6 sides) also has lines opposite each other.
