WALT: Going back and re-doing the wrong math questions.

For math in room 5, we have to go back and redo the wrong math questions. 

I have done my whole sheet cause they were all wrong.  I have been learning to round each number to the nearest 10.

e.g 1031- it would be 1030 cause you would just take the 1 off the 31 to make 30. then add the 10 to make 1030.
