Use of Technology in this Lesson

http://nlvm.usu.edu/en/nav/frames_asid_323_g_2_t_1.html?from=category_g_2_t_1.htmlThe website above was throughout the entire

lesson so children could build their own bar graph for the first time. It keeps things nice and neat which is important because the class would lack experience in making a bar graph. Also, its very user friendly and would keep children from being frustrated.
