A demonstration on how to collect data about favourite flavours of ice cream and organise the data into a block graph. How can we find out which is the most popular ice cream flavour? We could try asking the question 'Do you like ice cream?' but is this a suitable question? If not, why not? We must ask the right questions to get the right data. Once collected, it is important to sort the data. You can display data visually in a block graph for easy interpretation.
Children could create a question for a class survey. They could then collect their own data and arrange it into a large block graph. Children could then analyse the results and answer a series of related questions.
