Do the Math, Online
We’re frankly amazed by the scope of lessons and activities that math teachers create for their classes with Key Curriculum Press’s Geometer’s Sketchpad. The $40 program will soon be augmented with Key’s LessonLink, an online extension of the program that will contain 500 different lessons when the online service debuts in September. Aligned to popular textbooks and state math requirements, the lessons are aimed at grades 3 through 12 to help kids visually reinforce key spatial relationships and math concepts. Seeing really is believing, regardless of whether it’s showing 7-year olds that triangles have three sides or exploring trigonometry for high-schoolers. The service costs $119 per teacher for a 1-year school site license.
