2.1 Tally charts and frequency tables

Think like a mathematician

Work with a partner.
A cereal company is offering six free gifts.

One gift appears in every cereal packet.

How many packets do you think you would need to buy

so that you have all of the gifts?

If you did this investigation again, would you do it in the

same way or do something different?
If you did this investigation again, would the results be

the same? How will you know which is the true result?

Look what I can do!

I can conduct investigations to answer non-statistical
and statistical questions.

I can record, organise and represent data using a tally chart

and a frequency table.

I can describe data and discuss conclusions.
