This title encourages children to explore the different ways they can move their bodies and to consider the different ways things move in the world around them - a roundabout goes round and round, a see-saw goes up and down. The concepts of pushing and pulling are explored and children are encouraged to experiment with these forces for themselves. The best selling Start-Up series of books have now been rewritten to emphasise the cross-curricular teaching potential of each title. They will provide notes and activities, spread by spread, highlighting ways in which learning can be extended in various subject areas for KS1. The other key changes on the original series will be revamped end sections featuring extension learning details together with the latest internet and web resource information.
