Go to great "lengths" to teach your students the distance formula with this set of 2 worksheets in the same format. There are 15 questions on each sheet. About half of the problems reference a grid diagram that emulates locations on a city map. An answer bank is included at the bottom of each sheet, and a detailed key is provided for both as well. They can be used as an individual or group assignment or as a quiz. The problems could also be cut apart and handed individually to students. If you have any questions or requests, feel free to email me at teacherminestore@gmail.com. Enjoy discovering something valuable!
