Think the answer is 570. Each unit is 190

Thanks for your help ☺

120*2 = 240 240+50= 290 => 1u 3u= 870 opps, read the question wrongly, from A to B, follow Hong's answer

Start -> A: 310 / B: 260 End -> A: 190 / B: 380 310+260 = 570

Hi,I m curious. It's only week 1 of school year. Has school started teaching problem sums?

Yes😊

Omg!

Thanks again for helping me

My girl started her p4 with concepts last year. Simple stuff. This year p5 same thing. I m shocked!

Thanks

190X3

I think they haven't really started yet. But models seems to start in P3. To be fair that looks more like a P5 problem than a P4 one.

Elegant

Unless the entire class has same level of math appreciation. Else not very helpful for pitching at such difficulty level at week 1. Those who cannot match up will not feel good.

I think it depends on the year. The kids have seen some models from P2. I think this problem is ok for early in P5. (NB - I'm neither teacher nor expert)

P5 ok. But at P4..all parents Jia you ! All the best to our kids.

Good luck to us all!

1→1=1² 2→4=2² 3→9=3² 10→?

Pattern 10= 10*10= 100 Pattern 21

Thanks

Welcome!

Hi, the shown working is correct and almost there. 12-10=2 4×12-10=38

54÷3=18 is what Janice have now. Difference in both cases are the same. 54-18=36 is the difference of 3u at first. 1u=12 which is Janice at first.
