One of the particular difficulties facing teachers in Primary schools today is that of challenging able pupils in mixed ability and sometimes mixed age classes. In many mixed ability classes the problem can be resolved by well-planned and effective differentiation. However, the difficulties of challenging very able pupils in mixed ability classes are more pronounced in the upper end of Key Stage 2. The book provides a bank of activities for able pupils and offers some help towards overcoming these difficulties. Some tasks and activities are of a longer, more extended nature, sometimes involving research, which may require pupils to use the Internet. There is scope in many activities for pupils to explore a line of enquiry which they determine themselves. It is intended that able pupils will be given a copy of the pupil page and expected to work independently of the teacher. Includes comprehensive teachers' notes.
