Timing

Lesson plan and supporting resources

Introduction 10 minutes
  • Introduce the lesson by explaining that they will be focusing on percentages and word problems, explaining that percentage is the number of parts per 100.
  • Begin by asking what 50% of 100 is and discuss and then 25% of 100. Discuss which number operation percentage is very close to (division).
  • Carry out some questions for multiplying by ten and by one hundred and discuss the place value and shift of the digits one and two place value columns to the left. Then do the same for division and explain it as the inverse of multiplication and the shift of the place value columns in the opposite direction.
  • Explain that to work out the percentage you divide the number by 100 and then multiply the answer by the percentage number needed to be found, eg 12% of 80 = 80 ÷ 100 = 0.80 x 12 = 9.6%. Practice further questions.
