Maths Strategies

In Room 7 for maths we have been working on addition and subtraction strategies. The strategies we have learnt for addition are
- rounding and compensating
- place vlaue

The strategies we have learnt for subtraction are
- place value
- equal adjustment
- revesibility

We have been learning to choose the most efficient strategy for the problem and to solve the problems mentally in our head. Here are some videos of Room 7 students solving problems. You can tell that they are thinking hard...
