Questioning

We will be understanding the importance of phrasing questions and learning about how certain data-handling resources are limited in the answers they can provide. We will:

• understand that the information on pictograms cannot be used to answer more complicated questions.
• use a range of yes/no questions to separate different items.
• understand what is meant by a binary tree.
• design a binary tree to sort pictures of children.
• understand that questions are limited to ‘yes’ and ‘no’ in a binary tree.
• understand that the user cannot use 2Question to find out answers to more complicated questions.
• match 2Simple item pictures to names using a binary tree.
• understand what is meant by a database.
• use a database to answer simple and more complex search questions.
