Sorry I don't know how to rotate the photo

can anybody explain this?.thanks in advance.

Can you accept this?

yes,but cannot guess the change in units,.thank u for immediate rep

What about this?

ok,6 parts so times 2

oh.yes,now i know.thanks a lot

2u +1769 = 4743

Thank you!

Hussain Sadiq that question is for year 3, they haven't been taught algebra yet...lol

he he he but Hussain Sadiq good job!!!

...by the way Hussain was my student in secondary!! Lol

Woops. Will leave the letters out and use shapes instead next time.

student teacher conference here.... he he he

...I should also mention in England before I taught bar modelling.

that how I teach my son who is in primary 3 using Algebra and my wife complaints.. Primary 3 still haven't learn algebra.. Opps

Linda Tay, pls post more of p3 questions for my p3 boy to solve.. :)

Don't know if this is correct method

Alex R. S. Chia, your method is correct but students learn to solve simultaneous equations only in the secondary school. Hence the Model Method makes such questions accessible for students even at the primary level.

Alternatively

😱 I'm totally rusty from these. I need to start revising before I teach my son. 😓

P3 uses model to solve. They r not taught algebra yet.

Not jus P3 learnt model method,my P2 ger is using tis to solve maths.I'm always glueless,starting to search online to upgrade myself.

The A and B. Method is more for sec 2. The unitary method is more for primary school

Algebra method only suitable for kids who have some knowledge of algebra.

add all the numbers together and you get 2 x of the total height of A, B and R. Divide by 2, you get the total height of 3 boys. To find A, use total minus B and R.

Thank you

A=1.475 B=1.585 R =1.375

This question has more than one solution as it does not have enough information about the breadth of the rectangle. That the perimeter is 56 means that values of x and y that satisfy 6x+2y=56 or 3x+y=28 (where x is length of square and y is breadth of rectangle) such as x=8 and y=4 will give possible areas of the figure. Area in this case would be (24x4)+3(4x4)=144 sq.cm. Another possible solution is when x=7 and y=7. Area of figure in this case would be 6(7x7)=284 sq.cm

Yes. This is a bad question because they didn't state that the breadth of the rectangle is equal to that of the square. For instance, if the squares'sides were 6 cm in length instead of 7 cm, then the rectangle will have a breath of 10cm.

Thank you
