Common Mistakes to Avoid

Place value errors in multi-digit multiplication – always align digits correctly
Forgetting to bring down zeros in long division
Not checking answers using inverse operations (multiplication ↔ division)
Missing units in word problem answers (kg, boxes, trees, $)
Misreading "perimeter" vs "area" – perimeter is distance around, area is space inside
Decimal point errors when multiplying/dividing decimals
