Can I work out the mode and range of a set of data and use this to answer questions?

Example review questions

  • Mr Rahman’s class did a survey of prices of packs of dried fruit at local shops and the market. The prices they found were:
    49p, 48p, 99p, £1.19, 56p, 99p, 49p, 76p, 49p, £1.29
    What is the mode of the prices? What is the range of the prices? How do you know?
  • During the 12 days of Christmas, the mid-day temperatures, in °C, were:
    3, –1, 5, –1, 1, 0, 2, 5, 5, 1, –2, –2
    What is the mode of these temperatures? What is the range? What does this tell you about the weather over Christmas?
 

Teaching guidance

This teaching guidance document suggests some of the key vocabulary, models, images and practical equipment that children should experience and be able to use. It also includes some teaching tips to provide a few starting points for ways of supporting children with this area of mathematics.

Number spinners

itp_number_spinners.png

This interactive teaching program (ITP) is an ICT-based tool to support the exploration of number, reasoning and problem solving. Number spinners ITP allows the child or teacher to generate 3, 4, 5 or 6 random numbers on up to 3 spinners. Numbers from 0 to 99 can be displayed.

Opportunities to use and apply

Possible contexts include:

  • finding out the range of heights of children in the Early Years Foundation Stage;
  • working out the most commonly needed sizes of jumper in different year groups and helping to plan the school order;
  • working out the dimensions needed when planning play equipment for the Early Years Foundation Stage area;
  • working out whether the overall class ability in the long jump is improving.

Confirming learning

Ask probing questions such as:

  • Write a different number in each of these boxes so that the range of the three numbers is 8.

  • Write a number in each of these boxes so that the mode of the five numbers is 9.
