K-6 Math in the News: Censuses, Counting People and Math

The Australian Federal Government recently conducted a survey; have you completed your form yet? Or are you waiting to see whether the Australian Bureau of Statistics website gets attacked again?

The recent national census really caught the attention of the Australian populace, mostly for all the wrong reasons. The official website couldn’t cope with the traffic to the site on “census night”, which was entirely predictable, and at the same time it was subjected to several “Denial of Service” (DOS) attacks.

But apart from that, what can we teach children about censuses? Here are a few ideas:

  • Governments use censuses to find out how and where to spend money on schools, hospitals, rail lines and highways
  • School math includes taking surveys, collecting data and analysing the results, just like in a census
  • Jesus was born in Bethlehem partly as a result of a census conducted by the Romans
  • People expect survey-takers and governments conducting censuses to protect their privacy

Teach Measurement Using a Rain Gauge

Standing in the Rain, Teaching: Video

Rain gauges measure rainfall by collecting a small sample and measuring how deep the water is. The trouble is, we are interested in very small units – in the metric system, rainfall is measured in millimetres/millimeters. How can you accurately measure such small amounts?

How can we use everyday examples to teach measurement?

Watch the video: I explain how a rain gauge amplifies the depth of water collected to make it easier to measure.
