Maths Portfolio Sample

Description:  In maths we have been learning about multiplication and division. We have been practising the folowing strategies with Troy to help us: S (Spliting), R/C (Rounding Compensating), PLAT (Proportional Adjustment), KF (Known Facts) and PVP (Place Value Partitioning).


Big Idea: My goal in maths is PLAT. (Proportional Adjustment) PLAT is basically working out multiplication facts using doubling and halving AND tripling and thirding. For example: 12 x 5. If  we were using doubling and halving we would halve 12 and double 5. That would be 6 x 10. That makes it easier and we get the answer 60. For the first question we had to use 2 strategies. One of the strategies I used was PLAT. The other strategie was KNOWN FACTS. Known facts is basically working your way up to the answer using facts that you know. For example 32 + 32. 30+ 30 = 60. 2 + 2 = 4. 60 + 2 = 62. Next is R/C (Rounding and Compensating) For example: 5x19. First we round 19 to 20. 5x 20 = 100. 100 -5 =95

Evaluation: I think I have done well in using my strategy effectively. I believe I have proven my understanding in using PLAT. I think I might need to work on using R/C because I rarely use this strategy  in my learning but instead use algorithm or PVP or even PLAT. 

Feedback/ FeedForward: You have done a good job at explaining your strategy. I like the way that you have presented your learning I learnt lots from it.
Next time you could try to add more stratigies to your brain and remember how they are all used!

  1. Aye, as always this is an exceptional portfolio sample. Your explanation is perfect, I even think an Alien could understand how to do maths based on reading this. Your Maths ability is excellent and I love how receptive you are to new teaching. Thanks for being awesome!
