The Time Timer is an essential tool for any classroom or artroom, which teaches children the concept of elapsed time and empowers them to manage their own time, making them more productive. Helping to manage the stress of transitions by showing “how much longer”, this great tool keeps students on task and allows teachers to keep moving forward. With small feet, a slimline handle and lightweight body, the Time Timer is easy to transport and to use at different heights in the classroom. Silent operation means that it is not distracting during testing. Can be set to any time frame that is one hour or less. Volume control dial allows you to control the tone volume to suit your working environment. One AA battery is required for operation (not included).
