3A Early Formal |
'No, it needs to be Right 5 because you have to think you're at A' 'So Back 3, Left 2 should get us back to C' |
||
'Forward 4, Left 5 would be a good move from A' 'Forward 2, Right 3 should get us there from C' | Choice among the 7 situations requires comparison, one at a time, with methods just modelled | ||
2B* Concrete Generalisation |
North 8, East 6 and North 4 should get the robot back to A' 'South 6, West 6, then South 6 should get the robot from A to Z' |
'A would be Left 45 degrees then Forward 5 by Logo' 'Backward 5 would get it back to A' |
