Maths Portfolio Sample

In Maths we have been learning about different strategy and how to do the differnt strategy and which stratiges are quicker and faster to use for us. I am on Stage 6. I am working on what strategies I do use that are quicker. At the end of this year I want to be able to show different stratages to what I knew before.

Big Idea:
The strategys that I used were Trial and Error, Reversibility, Borrowing and Equal Additions.

Questions and My Answers:

1) Trial and Error


345+289=

300+200=500
40+80=120
9+5=14

=634



2) Borrowing

      215
    - 155
____________

    =060


3) Equal Additions

289+137=

290+138=

200+100=300
90+30=120
+8=128

=128



4) Reversibility

    289
  - 155=

155+_____=289


+5=160 +40=200 +80=280 +9=289
______________________________
155                                                289

80+40=120
+9=129
+5=134

=134


Feedback/Feedforward: Wow Amy! You have a really good rage of strategies. I can really tell that you were practising a lot and thinking a lot when you were writing down the answers. One question: "What other strategies do you think might be the best choice for an equation?"  Oh, and what I think you need to work on is to add more detail while recording what work you have done. -Aye


Evaluation: I think I have done a great job with my Maths but I really think I could work on showing differnt stratages next time and I could add more detail about what I am showing you.
