In this unit pupils develop their awareness of different types of questions, how they can be asked and how ICT can be used to answer them using different types of software. They learn that some of the programs they have used so far to present data cannot provide the answers to some specific questions. They begin to realise that programs have limitations and that it is knowledge of the facilities and tools offered that helps us to select the most appropriate tool for a task. Pupils learn how to ask questions that can be answered with yes or no responses. They have opportunities to work with a prepared file on a binary tree program to practise their questioning skills. Pupils will have opportunities to enter and store information using some of the different types of ICT information resources that are available. Pupils will use what they have learned in this unit to help them to ask more focused questions to find specific information when studying Units 2C 'Finding information' and 3C 'Introduction to databases'.

Listed below are sections of the taught activities suggested in the unit, with support materials to assist teachers. Almost any topic could be used, e.g. pets. Ask the children to think about their pets, ask one or two to describe their pets. Make a list of questions to ask about pets. Make a class pictogram using a prepared set of pictures. Ask the children to use the pictogram to answer some simple questions.
Games such as 'Guess Who' provide an excellent way of practising the asking of questions with yes or no answers. These are the types of questions that will be practised over the next few activities.
Construct a paper-based binary tree for a set of objects, e.g. shapes. Children should be encouraged to ask simple questions.
Use a commercially-prepared file on a binary tree database to replicate this activity, or create your own on an appropriate topic. Ideally there will be relevant artefacts or visual aids available for children to handle, ensuring that this is a concrete activity. Children's Sheet (Decision Tree) Show the children a simple completed database and demonstrate how the search tool enables specific questions to be answered. Encourage the children to ask their own questions and see if they can use the search tool to find out the answers.

2Count is a program that allows children to easily create pictograms. It has the added bonus of being very effective using it diaplayed on an Interactive Whiteboard because children can come up and click on the one they have chosen, and see it being added to the graph. 2Count is part of the Infant Video Toolkit 2 from 2Simple.
