[color=#1551b5]Contains a sampler of several Geometry lessons where students actively use GeoGebra to DISCOVER many theorems and other principles/concepts for themselves. Many of the worksheets in this book contain PDF copies of the discovery lessons I have used, much to students' success, within my classes. For an exhaustive resource containing over 400 worksheets mapped to one (or more) of the CCSS-High School: Geometry standards, go to [url]https://www.geogebra.org/m/yCs9zxry[/url][/color]
