Hands-On Equations 3 对比 Graphing Projects 的使用情况和统计数据

"Great intro to Algebra!" This Hands-On Equations Level 3 app is intended for students who have already completed Level 1 and 2 of Hands-On Equations and who would like the challenge of more sophisticated equations involving negative numbers. In Level 3, the student solves equations such as 4x – (-4) = -8 and 3(-x) + 2 = -10 + x, which contain negative constants. The green numbered cube, which represents the opposite of the red numbered cube, is introduced at this level. Since the red and green number cubes are opposite of each other, when they are together on the same side of the balance, their value is zero and may therefore be removed without affecting the balance. A video introduction is provided for each lesson. (See the sample YouTube video at http://youtu.be/VFYQ47EAqZw.) Each video introduction is followed by two examples and ten exercises. It is essential for the student to view the lesson video prior to attempting the examples and exercises for that lesson. Hands-On Equations is the ideal introduction to algebra for elementary and middle school students. Not only will students have fun and be fascinated with the program, their sense of self-esteem will be dramatically enhanced as they experience success with sophisticated algebraic equations. High school students struggling with algebra will likely experience success and understanding for the first time as they work with this app. More information on Hands-On Equations can be found at www.borenson.com and on YouTube.
