Description: In Troy A, we have been focusing on the appropriate/efficient strategy. This term, we are doing it around multiplication. In every workshop I attened, I want to find the most efficient strategy to work from. 

To solve this question I doubled 35...

Twice: 70

Four Times: 140

Five Times: 175

Since that's 5 away from 180 the answer would be 5 remainder 5 which is 6. This strategy is KF

To solve this question you split the 180 into 70, 70 and 40. Now you see how many 35's there are in70,70 and 40, which gives you the answers below that. 2,2 and 1 plus them together and that equals 5. But, since there's 5 left in the 40 it will be 5 remainder 5= 6 I used the strategy 

To solve this question you double the 15 to make it a 30 and half the 12 to make 6

3x6= 18

Add a 0

30x6= 180

I used the stratergy doubling and halving stratergy which is technically PLAT

To solve this you take away 2 from the 12 to make 10 and I know that 15x10= 150

15x2= 30

150+30= 180

I used the stratergy PVP

Big Idea: So in the workshops Troy provides, we focus on multiplying and dividing in different strategy's. These are some of the strategy's...... 

PVP= Place Value Partishoning

KF= Known Facts

RV= Reversibility  

PLAT= Proportional Adjustment 

These photos are my working.......... :D  

Evaluation: I think I improved in my division and multiplication during the workshops because the  way that he tort me really motivated me to do better. I think I need to work on my multiplication and thinking quick.

Feedback/feedforward: I like the way that you worked it out. You only have abit to work on and that is the zero on the PVP looks like a 6
