Common Mistakes to Note:

Forgetting to regroup when subtracting across zeros (e.g., 8000 – 3456)
Adding instead of subtracting when keywords like "left" or "difference" appear
Not aligning numbers by place value when adding/subtracting
Making errors in carrying/borrowing

Marking Notes:

Award partial marks for correct method even if final answer is wrong due to minor calculation error
Require working for full marks in Sections B and C
For word problems, the correct operation must be identified for any marks to be awarded
