Fun-Size Activities - Great for lunch?? Fun-size activities are short 5-15 minute activities that enliven lessons. They range from short games and word plays through to quick demonstrations. Many of these have been kindly donated by teachers. Fun-size is particularly useful when you are working outside your specialist area at KS3. These activities are based around the 'Who am I ? ' theme. If you would like to contribute ideas for future themes, please get in touch. in Public bookmarkswith activitiesbritishgamesthemesuk
