1-1 est. strategies
I couldn't fit estimation, that's what the est. is for.
|How do you use front- end estimation? (decimals)||You add the front- end digit first, then you estimate the back digits to ether a full number, or nothing then you add the full numbers to the front- end digits.|
|How do you use compatible numbers?||First you set up the quotient, then chose compatible numbers, then simplify.|
|How do you estimate a sum or difference?||First you round to the nearest whole number, then you solve it. (example: 3.27- 0.88 3.27 = 3 0.88=1 so 3-1=2)|
