Add whole numbers in your head quickly
Multiply small numbers without using a calculator
Divide numbers exactly using known facts
Check answers by thinking about number patterns

Common mistakes to avoid

Rushing through sums and leaving out a step. Pause and check each number before answering.
Confusing multiplication facts with addition facts. Learn your times tables clearly first.
Forgetting to use exact division when the numbers divide evenly. Match the dividend and divisor carefully.
Mixing up signs or place values in larger numbers. Read the question slowly before you calculate.
