Re: P3 Maths

u = (120-48-40) / 2 = 16

u should post in AskQ. Why use algebra? Model is easier for kids.

Let x be no of sweets given to S by J

120 - x - 40 = 48 + x
2x = 32
x = 16

OR

(120 - x) - (48 + 4) = 40
2x = 72 - 40
x = 16

Hi, Thanks thanks.
Modelling is hard to understand so hard to explain.

Re: P3 Maths

I think the more important question is whether your child prefers model or algebra.
