The Ladybird book Stone Age Man in Britain is part of Series 561 - Adventures from History. At the time my copy was published in 1961 it was the only book in the Prehistory sub-category.
The book begins with an introduction to the world as it was before the Stone Age, although with no real timescale, just "thousands of years ago". It's specifically about Britain, after the glaciers receded and Britain became warm enough for the very earliest ever people to live here to move across from France (which was actually joined to Britain then).
The book describes a very basic early civilisation of cave men, with no metal, or pottery, although they did have the knowledge to make fire. They hunted wild animals like the mammoth and sabre-toothed tiger, animals which have now disappeared. Then about six or seven thousand years ago a new group of people called the Neolithic people arrived in England, a more intelligent civilisation with greater knowledge of weapons for hunting and a more developed brain. These were the Stone Age men, able to hunt with flint knives, fish, build houses and sew clothes.
The book describes the way that they lived and the skills that they developed in some detail. For example, the process of making a boat from a hollowed out tree trunk, the beginnings of farming, and finally the building of Stonehenge.
It's a really fascinating book, and as always the illustrations really bring the information to life. I know that the Stone Age is a subject that Harry will be covering at school at some point, and this will be a handy reference!
