A sand timer is a great time management tool to help your child focus for a quick spurt of time. It provides a fun and easy way to measure time. It teaches the concept that time passes as sand falls between one chamber and the next. 

Use them for everything from homework and studying, to exercising, tooth brushing, and everything in between!
