### PRODUCT DESCRIPTION

In the past, I used to lecture my students about the distance formula, and I was never satisfied, because they really didn't understand it in terms of the Pythagorean Theorem.

Over time, I started to shift to having them discover the formula, but the problem is that I was still very lecture-focused: most students would watch me go over every step in excruciating detail, and when it was their turn to perform, there were just a few minutes left in class.

I think this worksheet strikes a happy balance: though I start class with a 15-minute mini-lesson to give them the basics, the bulk of the block is spent with them working through the problems. The worksheet does also include the formula in a gray reference section, so those who straggle, those who were absent, or those who just need to check their work have something to refer to.

I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.

The file includes spiral review problems.

This worksheet is intended to be written on directly.

Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.

Immediately before this worksheet, I use the worksheet named 'Discovering the Midpoint Formula in Geometry Fall 2013' (http://www.teacherspayteachers.com/Product/Discovering-the-Midpoint-Formula-in-Geometry-Fall-2013-1070170), and immediately after this worksheet, I use the worksheet named 'Polygons and Vertical Angles Fall 2013' (http://www.teacherspayteachers.com/Product/Polygons-and-Vertical-Angles-Fall-2013-1082496)
