Two durable tools essential to success in the classroom. These two tools are must-haves for every student eight years old and up, and their durable designs mean they’ll withstand rough use by kids. The plastic compass creates perfect circles and arcs with a single motion. A locking mechanism helps prevent mistakes. A dial marked with both-inch and centimeters makes measuring easy, and the innovative plastic safety tip holds the compass in place without tearing or puncturing the paper. The plastic protractor features bold inch and centimeter marks that simplify measuring, and a clear, shatter-resistant design allows kids to see their project for improved accuracy.
