AA-AM Solving mathematical problems by using the best strategy.
1. Solve by using place value Card 6 (adding the parts).
Rick drove 359 kms on Thursday and 355 on Friday. How far did he travel altogether?
2. Solve by using rounding and compensation Card 5 (making tidy numbers.)
Hine’s team has scored 296 points this season. Last year they scored 277 points.
How many have they scored over the 2 seasons?
3. Solve by using reversibility. Card 15 (changing into an addition problem) then jump the number line.
There were 463 vehicles in the in the carpark. After lunch 168 left. How many cars were in the carpark now?
