Y5 t2u11 numbersequences

  1. 1. WALT:To recognise andextend numbersequences
  2. 2. 58, 67, 76, 85, ?,103, 112, ?What are the missing numbersin this sequence?How do you know?
  3. 3. The missing numbers are 94 and121. It is an ascending sequence.Rule is NN = LN + 9
  4. 4. NN means ‘Next Number’LN means ‘Last Number’REMEMBER:
  5. 5. 227, 219, 211, ?,195, 187, ?What are the missing numbersin this sequence?How do you know?
  6. 6. Rule is NN = LN - 8The missing numbers are 203and 179. It is a descendingsequence.
  7. 7. 722, 632, 542, ?,362, 272, 182, ?1. What are the missing numbersin this sequence?2. Is it descending or ascending?3. What is the rule for this sequence?
  8. 8. It is an descending sequence.The missing numbers are 452and 92.Rule is NN = LN - 90
  9. 9. Can you checkthe rule for thissequence usinga calculator?
  10. 10. TASK: You are now going to use calculators togenerate sequences. They must includeascending and descending sequences. Record your rule and generate 8 terms inthe sequence. Then omit 2 numbers andgive the sequence to your partner tosolve. Also try and use sequences that includenegative numbers.
  11. 11. Can you work out the missing terms inthis sequence?23, ?, ?, ?, 47How could we find the middle term?
  12. 12. Use the same strategy for thissequence?37, ?, ?, ?, 25
  13. 13. What if there are four missing terms?19, ?, ?, ?, ?, 39What is the rule for this sequence?
  14. 14. And this one?57, ?, ?, ?, ?, 12What is the rule for this sequence?
  15. 15. By the end of this lesson, you shouldbe able to: Recognise and extend numbersequences formed by counting on orback from any number. Explain a rule orally and in writing.
