So many things that we look at in Maths have a regular steady
pattern that we can find and explain. For a change, let's look at
things that happen more randomly.
We sometimes throw dice, toss a coin or use a rhyme to choose
something at random. In this problem, we'll have a look at
something a bit different - birds in the garden.
So, let's do some bird watching in our garden - at home or at
school. People who do a lot of bird watching keep a chart to record
which birds visit their gardens. The chart might look like
You might want to use a similar chart over a period of, for
example, a week. Or you could just do it for one day and note the
Once you have a few items recorded, it would be good to have a
discussion about the information you have recorded and to ask
yourself some questions about it.
How many birds of a particular type did you record on each day (or
Did you see the same type of birds at specific times of the
How may different types of birds did you see each day (or each
You will be able to think of many other questions too.
Are you able to see any patterns in the information you collected
or do the sightings of birds appear to be quite random?
If you do find any patterns, can you try to explain why, or at
least have an idea of the reason?
