Maths - Statistical Investigation

WALTs:

  • ask a question to investigate, then gather information
  • sort objects into categories
  • display findings using a pictograph
  • talk about the information on the graph
  • compare the information on the graph
  • ask questions about the data shown

 Our Question:

Who has the biggest feet in Room 3?

We traced our feet onto paper, then measured from the big toe to the heel - thank you Loretta for helping us to do this accurately.  We used point 5 to record 'half'.
We cut out our feet then worked together to sort them.  We solved the problem of "what can we do when some are the same size?" and made this pictograph by labelling each line of feet. A small group of children solved this problem after lots of talking, as they had thought that the feet could be put in a single line.

To finish our maths today we talked about what we could see that would help us answer our question,  "Who has the biggest feet?"  "Three people have the biggest feet.  We thought there would be just one person."

Other statements were:
The smallest sized feet are 18 centimetres long.
Three people have 19 centimetre feet.
Lots of people's feet are 19.5 centimetres.
More people had 19 centimetre feet than 18 centimetre feet.

We asked each other questions about what our display showed, and answered these from what we could see.
