I used to do this with year five and six groups; the children could talk about anything that interested them, visual aids encouraged,which is why we had a visit from a doberman puppy, a pet snake, a horse and a baby sister, plus ballet costumes, piano playing, collections of china pigs, Japanese cartoons, football trophies et al. Some children did find it nerve-racking but no-one backed out, and I saw a really nice side of my pupils.Their response was excellent; they listened intently, asked sensible questions and were extremely complimentary and supportive, particularly to the nervous ones. The really terrified did it with a partner. They all received a merit mark having done their talk, which was an incentive.
