Big Idea: Our teachers gave us this sheet to do. For the first question I used the rounding and compensating strategy. For the second question I used the equal addition stategey. For the third question I used R&C and place value stategey's and for the final question I used place value.
Feedback/Feedforward:I like the strategys you used but next time you could make your writing a bit clearer. Ana
Evaluation: I think I did well at the equal addition strategy. But I should try to use the reversibility strategy more often because I stick with the stategey's I know and I'm comfortable with.
